Official Pontiac Street Engine Combo Thread, Post your combo here!
I would like to start this thread and make it a 'sticky' so others can see what different combinations people are having success with. This will be a very useful archive to use for future reference for all PY members, your post won't disappear from the top of this page.
'Traditional' 1955 - 1981 Pontiac engines only please. Aftermarket blocks, heads and cranks that fit the 'original' Pontiac V8 engines are also part of it, they're definitely still all 'trad' Pontiac pieces. The '66 -'69 Pontiac OHC-6 engines are welcome. No LSX, Chevy, Olds, or any other engines. Please post the component combo of your running street engines only, not the combo you're now building or might build someday. The more details, the better. If you've run your car down at your local dragstrip, we sure want to know what E.T. and MPH it ran. Let us know what kind of car the engine resides in and the car's weight if you know. We need to know what transmission, torque converter (if auto), rear end gears and rear tire size you're running if posting dragstrip results. If you've had it on an engine or chassis dyno, please share the HP/TQ numbers or your dyno sheets. Everyone has a different idea of what constitutes a 'true' street engine. Some folks drive their near-stock street engines hundreds of miles on road trips, other just rumble around town with their really wild street engine in a thinly-disguised race car. As long as you use your car on the street on a regular or semi-regular basis, we want to know all about the engine. Post a picture of your engine if you can or of the car your engine lives in (one only full-size pic please), we would all like to see what your Pontiac engine looks like. Do not post pictures that are so large that we have to scroll back and forth to read the thread. Please reduce the size of your pictures, if you don't know how please ask in the 'Test & Tune' forum. Post all the thumbnails you want, you can download up to 5 of them in the current format. The whole point is to keep this thread easy to read. I will delete pictures that are too large (no larger than 640 X 480 pixels). Please help keep this thread 'clean', nothing other than your engine combo can be posted in this thread. If you have questions, please send a Private Message to the engine's owner or start a new thread asking your question. You can link to the individual post you are referring to by clicking on the post # in the upper right hand corner of the post, then copy and paste the link that appears to put in your new thread. This is a reference thread only, not a Q & A thread. It loses usefulness with a bunch of questions and answers mixed in. I will delete any posts by members who are not presenting their engine combo. Please do your best to put up a quality post on your combo, spend a little time so others can benefit. Step up and post your street engine combo, Pontiac fans! |

Great site idea B-Man.
http://www.pontiacstreetperformance....455jh2006.html I added this link as it pops you into more details than you could ever hope to see in one place. Plus, I am a terrible typer and this way, you can see it all correctly organized. Every single "secret" is revealed in grand detail here too. http://www.pontiacstreetperformance....455jh2006.html I will also add a link to the car in action. No dyno numbers but some real strip numbers to share. http://www.youtube.com/watch?v=8GHYxPqePv8 And here is one so those interested can see how truly quiet this street car is when it runs mid 11's. If you listen, you can tell by the low rpm it is geared rather mildy (3.31) And, since both 3" tailpipes come out this side, you can really tell how quiet Goerlich's large case 3" XLERATORS are, even on an engine this powerful. http://www.youtube.com/watch?v=Ta6kP3itZx8 Tom

Dropping .01 and getting + 2.51 MPH was great, especially for free! Once I get a little more converter (Redneck "Tight" 3500) and upgrade my fuel system (-8 from cell to regulator) it should run low 12's! I need a better 60'!!! JD P.S. ??? Unknown yet how the new combo will respond! Hopefully weather permitting I'll know by the middle of Nov.!

First Gen 455 Build
Short story before I get to the drivetrain specs. Originally my wife's 69 Firebird Convertible came from the factory with the HO Six Cylinder engine but some time in it's life someone put a 350 hp, 350 CI generic GM motor in the car. We drove it and enjoyed it like that for a while but it was never very reliable. After paying good money to have the heads rebuilt to only have the bottom end start making noise shortly there after I decided to give the car back its Pontiac heart.
I am not engine builder so I contracted with Pontiac Greg at pontiacengines.net in Longmont Colorado to build a stronger than stock Pontiac 400 CI engine. Here is where the story takes an unexpected turn... Greg calls me back a couple of days later to say he found in his inventory of blocks a 1976 WX Code 455 HO Block and he would build me this for the same price as the 400. So here is the build: 455 +.040" = 464 CI 4 BBL Dual Plane Intake Holley Street Avenger 850 CFM Carb Felpro Neoprene Rear Main Seal Eagle H Beam Rods 8.5 Compression @ 5000' Ultradyne Custom Ground Cam Shaft Kauffman D-Port Heads - Mild turn on intake & exhaust Ferrea valves intake and exhaust Accel Eletronic Billet MSD Blaster Coil Hooker long length headers rest of the exhaust still to be determined. Since this is my wife's car it is matched up to a numbers matching (1969 Firebird) TH400 Trans capable of handling 800 hp and 10 bolt 4.75 posi-traction rear end. The car also has after market disk brakes all around and as you can see by the picture sports 15" Craegar SS wheels. These where the aftermarket wheels to have in my hs days... I am not quite done with the install yet a few odds and ends to tie up but the inital fire up is expected within the next month. Depending on cash flow and parts availiblity that is... ;-) Dan Last edited by dhaney; 04-21-2013 at 01:24 AM. |

I just finished up a stroker 400, going into a '68 Firebird convertible. This was a milder build, but thought it may be of interest to some.
The owner wanted the motor to look stock, so it has the iron intake, q-jet, stock 400 block, iron longbranch exhaust manifolds, along with the "16" heads. He wanted it to be mild enough to drive in traffic, but enough torque to get it moving. We were not too worried about peak hp/tq numbers, but wanted a broad & smooth powerband. Dave @ SD Performance did the heads for us, setting them up for a hydraulic roller. Dave Ray did one of his conversions on the stock distributor. Dan Finn rebuilt & modified the Q-jet. We used a forged 4.21" stroke crank, PPR's newer I-beam connecting rods (stock length), and a set of custom Race-Tec pistons. The pistons were dished, giving us a final compression ratio just over 9.0:1. The pistons also were made to use modern rings, with a 1.5/1.5/3.0mm ring package. The cam is my design. I kept the intake duration at 224 @ .050, as my calculations showed that any larger and I would lose low-end at this compression ratio. The exhaust lobe is bigger than what I once would have selected, but again the numbers suggested it would help me extend the power band, which was one of our goals. The LSA ended up at 114. As described above, but with 2.25" elbows coming off of the longbranch manifolds (the only pipes we had, which would mate to the dyno's exhaust system), this combo made 494.6lb-ft @ 3600rpm and 408.8hp @ 4900rpm. Torque was 485.8 @ 3100 (where the dyno started reading), stayed above 480 until past 4000, and was still 413.8 @ 5100 (where we ended the pull). HP hit 401.8 @ 4600, and was 401.8 @ 5100. The motor also idled nicely at 690rpm! The owner picked up the motor today, and should have it in his car soon.

350 HO 'clone'
Here's a mild 350 combo I put together for a '69 Firebird that my brother owns, a heavily optioned car (A/C, power discs/steering/windows/drivers seat, deluxe interior) that weighs over 3700# without the driver.
1968 350 (354) bored +.030 so it now dispaces 360 cubes.The lower-end was rebuilt with cast pistons and stock cast rods by a previous owner and was still fairly fresh, I added the rest of the parts listed. 1969 400/428 #46 heads, cheap valve job/used stock springs, stock press-in bottle-neck studs, not milled for added compression, ports untouched. Crane blueprint 068 cam (212/225@.050,.407"lift) advanced 4 degrees running stock 1.5 rockers and adjusting nuts torqued to the stock 20# spec, Cloyes Tru-Roller timing chain set. Stock 1969 iron intake, exhaust crossover still functional, 1972 400 750 Q-jet rebuilt with no mods, stock 1974 B-body aircleaner 'donated' by a 455 engine. Stock points distributor. Stock log exhaust manifolds, cheap 2-1/4" dual exhaust TH400 trans with shift kit added, TCI Saturday Night Special converter, approx 2500 stall. 1980 T/A 10-bolt 8.5 rear with original factory 3.42 posi, 235/60-15 street radials, no traction devices. This car ran a 15.21 ET at a 2800 ft. altitude track, launching easy so as not to spin the 235/60-15 street radials. Using the standard correction factor for this track the ET at sea-level would be in the 14.80s. With good traction tires and a harder launch low-14s are easily there. Pretty much all stock or stock-replacement type parts were used for this engine build. The 068 cam was chosen with .407" lift because of the press-in studs. I didn't want to overstress the valve train and I wanted the simplicity of using the stock 20# valve adjustment procedure (actually no adjustment, stock non-adjustable valvetrain). A no-frills 350 built on the CHEAP and a decent runner. |

my combo. 68 .030 400 with stock crank and zero decked
KB dished pistons with Eagle rods, assembly balanced 9.4 comp with E- RPM heads Comp Cams XR276HR-10 cam (lift 552 and 561 with HS 1.65 rockers 224 and 230 at .050 Ls 110 cam set at 106) RPM intake with 750 E-carb, MSD 6A box with factory dist and composite gear Summit 80 GPH mechanical pump, and 11" DF centerforce clutch Richmond 5 speed with 8.5 and 2:56.1 gears Factory long branch manifolds with Pypes 2.5 with X-pipe and race pro transverse muffler Chassis dyno showed 292 HP and 350 TQ at the wheels with out of the box 750. I tried the 800 and it woke it up pretty good so I tried a 950HP and the gain was noticable. I wish that the funds were there to dyno this thing again( this time with someone who is willing to mess with the carb to fine tune it. I took it in and the 800 E-carb was not running right and they just pulled it off and installed the 750. From 2600 to 4600 it showed an A/F of 12.5 steadily going down to 11.1 |
