The engine sounds amazing.

Yes, the plan was to be able to drive it on the street on pump gas.
But for the sake of being extra safe, it will have the 50/50 mix on the street and mostly VP 110 leaded when I'm running it hard on the track.

What a great build.

I hope you kick some arse!

[Skip Fix]

Nice build!

What it the height with the High Ports and Northwind/Dominator under the hood? Scoop on the hood?

I haven't installed the engine with high ports and northwind in the car yet. It's gonna be pretty close and need a custom scoop base. I want to keep the shaker functional.

I dont think other makes realize the instant torque of a Pontiac. I would think coming off a corner would be very telling. If you ever come to Beaver Road course in Pa. near Beaver Falls I'd like to be there.

[PAUL K]

Great job! Thanks for sharing.

Formerly Beaver Run? Raced motorcycles there many years ago, soon after it was built. Back then facilities were minimal but the track was excellent.

I thought about leaving it natural aluminum, but it just looked too generic. So I went with my favorite Pontiac blue.

I went to an open track day at Mid-Ohio last fall just to watch and learn. I got to talking to a few of the regulars about my project. They were amazed to hear I was building a Pontiac engine and one of them said "as long as you can make 450 hp, you should be able to keep up with the pack". Hehehe

Eric

Well, Roger Bolliger's Trans Am is putting down 700 HP and 670 lbs of torque and is killing it.
You guys ought to do pretty well with 600 HP and 590 tq.
Going to make some Chebby drivers wonder what hit them when that thing pulls around them coming out of a corner.
Pontiac's TTF.

Great Job Eric and Team!

[GoatZillaRacing]

I built a 350 Pontiac for a circle track guy and he was killing all the 350 Chevy guys. For two years in a row he was Champion and then the sanctioning body made it mandatory to run a 350 Corporate engine. They said it was to keep costs down but I know he had less money in that Pontiac than most of those Chevy guys. They spent more more and got way less torque... and trophies!
Pontiac's Rule!

I don't guess that an iron block would make more power. My main goal here was taking weight off the front of the car to get closer to 50/50 weight distribution.

As far as the cam, I told Tim Goolsby that I wanted to make at least 600 hp, didn't want to run above 6500 rpm and wanted a wide power band. Nailed it! That cam doesn't want to idle below 1000 rpm, but OMG it's happy and sounds badass idling at 1200.

The first thing I noticed about my High Ports were how heavy and solid they felt picking them up . Nice beefy head with plenty of room to port should you ever want to.
Mine have a 2.20 valve and with a little bowl work they go 352cfm @ .700 and 359cfm @ .800 lift. So they are done just past .700 lift in my case.
I will be looking forward to hearing about your guys latest Pontiac effort.
Can you put up a vid of the engine so we can hear how it sounds ?

Is that what's now Pittsburgh International in Wampum, PA?

[sdbob]

I believe so never been there. From net track looks nice. My good Pontiac friend Gary lives near there. John Labuda (56 Pontiac gasser at Norwalk) races his Fiero there. John says he helped there to get his' feet wet'. I always wanted to road race always(Herb Adam's ,Chaparrals). Drag was cheaper.
ELarson are you running leaf spring rear suspension? I still have that 74 good TA shell.

[Tom Vaught]

Good Job Eric, and team. I will have to come and watch you race at a event in Michigan or Ohio.

Just curious, what LSA is the camshaft, and did you try a spacer on the intake?

Congrats on the build! I like it!

You should be able to get some sort of air :filter in there if you build a custom base. If you were running a Victor, not a chance. When I switched mine from a Victor to the Northwind the clearance difference was pretty drastic. Highports are great but that extra 1/2" in intake height they add is a pain.

Edit: With highports, Victor, and Dominator

[hurryinhoosier62]

Eric, it ought to be fun watching the faces of all the LS guys when you out accelerate them out of the curves! With that torque curve you could stay in fourth or third most of the time.

Ultradyne lobes # F4 and F19.
Tim wanted to do 112 LSA to give a broader power curve. But there were no cores available at the time so he reground an old cam that I had and could only get 108 LSA out of it. The dyno numbers look pretty broad on this one, but I'll put it on the track and see how it feels.

Didn't consider a spacer since I'm already in a bind on shaker clearance.

so the HEI had spark scatter for reluctor driving the MSD-6: whether 1-side grounded or twin wire balanced into the MSD-6, i figure electrical interference.

..just not an HEI without the 4-pin Module. Giving a full-up HEI a chance without the MSD-6 might be nice.


Aside from the dizzy stuff, the rest of the build is super.

If he was married to the OE HEI, the next test would have been to lock out the mechanical advance in the HEI Dist. and make a pull. That would have separated electrical from a mechanical advance issue for certain. But after chasing the problem for over 4 hours, the quickest test was to install a known good distributor. We did that and it was clean as can be on the next 4 pulls at various total timing settings. Personally, never been a fan of HEI anyway. Big, clunky distributor always in the way, crammed up against the firewall. Integrated coil always overheating the cap and burning through the rotor. I understand many, many people love them and have good luck with them. Just not my favorite unless a restoration. Just like my insistence on always running a 80 LB oil pump in all my performance builds. Many people think that's just a stupid waste of a 1/2 HP.
