The IA2 has been through several foundries and machine shops I understand. And they have things worked out closer to race spec since around 2016 from what I hear. Does anyone have any experience with these later blocks and how close they are vs the early ones which needed quite a bit of work ?

There are a ton of very fast cars out here in this area, but they don't drive them on the street nearly as much as dad drives his, and come Pontiac and Muscle car race time at the local track, they never seem to show up. |

Anyone remember in 2006 the Butler Performance 601 cu in engine featured in Hot Rod magazine. The monster engine created more than 700 hp and 750 ft. lb. torque on pump gas.

Isn't that the one that had a really docile camshaft in it? Or am I thinking of another one?

Spotts was selling IA2 505 short blocks, assembled, for $6500. You can email and see if that's still a valid price, if it's not, it's very close to that.
spotfam@verizon.net Toss on a set of E-heads, a cam, and button it up with oil pan, valley, TC, etc, and you can make some good numbers with a virtually indestructible short block. Can even build it in stages. You can step up to a 4.5 crank (535ci) for just a hair more. You start comparing those numbers to what others are paying for engines and you will see the cost is not much more. EDIT: I just picked up my 535 from Spotts yesterday for the 'bird, will do a thread on that. Went mild on the cam since I only have 315cfm heads and 3.25 rear gears, but it will still be plenty potent. .

I know what you are saying about stock blocks. My 455 putting out 550+ HP for many years was never decked or line honed and it is still doing fine. The factory marks on the deck are still there. Its a 4 bolt block and I just installed main studs without a line hone. Its been "good enough" to get its intended job done and be very durable. Way back when I originally had the block done and asked Dan about line honing the block he told me Pontiacs were generally pretty good and he had seen quite a few good blocks messed up line honing over the years. So I left it as is. The 461 I am doing right now was line bored and honed by Dan fitting the splayed billet caps. After he passed and I got the block and had it checked out by the best local shop here and was told it was dead on the nuts. He was impressed So I just had it tq plate bored and zero decked. This engine will get a bit more attention than my old 455. Really looking forward to how it turns out. Dan's last engine. |

Larry, that 600-inch Butler engine had a Comp solid roller with 280/288 at .050, 0.678" lift intake & exhaust and I think it was ground with a 112 LSA.
4.375 stroke 5.00 bore 9.72 compression Edelbrock Wide Port heads Victor intake w/ 1190-cfm King Dominator WD Creech built a 606-inch combo. .

I remember that build Steve C, I used to think wow! A 'mountain motor' Pontiac! Heheh!
I went with a 'tame' solid roller that I had mentioned to you before, the Hi-Tech lobes, thanks for that info! Ended up with a solid roller 260/267, 112LSA, .421 lobe lift, have 1.65s. Sure I will be happy with it! Port matched Northwind, Sniper XFlow, hyper-spark, should be fun with a TKO. .

Just to throw it out there, I have one of the early run IA2 iron std deck/bore blocks, and to go to 4.350 bore, it was recommended I sleeve two bores, which I did. I will see if I can get more specific info regarding, but that block was one of the 'prepped' blocks ready to assenble from Butler. It would have been fine at the bore it was delivered as, but it was one of those 'better not take the chance' things for me. (going to a larger bore)

Dad is using standard Edelbrock round port heads, the old style with bathtub chambers, his solid roller was smaller on duration at 269/279 @ .050 but with .436/.441 lobes, and an old 950cfm 4150 HP carb that I set up years ago. He made 724hp and 764tq and we never actually found the high peak tq numbers, Tony wasn't starting the pulls until 4500 where peak torque was already falling. |

There are some issues with the Hot Rod magazine reporting of that 600-inch Butler street engine using the IA2 tall deck block, one short article in 2006 stated the Victor/1190 cfm carb set up and another reported fuel injection.
The latter stated 738 hp at 5800 rpm. "We considered a 6,000 rpm power curve to be sufficient running room, enough to let the torque build to very high power outputs, while producing a combination that will be easy on the internal assembly and valvetrain. Abnormally large displacement is the key here, providing staggering output without requiring destructive rpm levels." And on the subject of monster Pontiac engines. Regarding WDCreech's 606-inch engine (actually a 605.5), one statement stated it replaced a 619 cu. in. engine. Back in those days Pontiac Dude stated 535 cu.in. seems to be the best bang for the buck with current aftermarket blocks and cranks. .

From WDcreech in 2009, not a street engine but of interest.....
606 cu in tall deck IA block, 4.39" JE pistons, 7.070" MGP rods hooked to a 5" Moldex billit crank, sheet metal tunnel w/2 1295 cfm Carb Smith dominators, a 286/308 at .050 duration w/.914"-.856" lift Erson roller cam. Incrementals: 60'------1.1981 330'-----3.4170 660'-----5.2920 mph-----132.01 1320'----8.2550 mph-----164.17 On this pass I had lifted before the stripe on a double breakout pass, but it was my quickest ever. On his 619-inch engine it had a 4.440" bore, but it was thin enough that it was filled, and he did end up having to sleeve it. .

I noticed on the install instructions that you can “borrow” a torque wrench plate, customer has to pay freight both ways...AP also sells that plate for $450.00

One thing that discouraged me on the IA block is that I was told the pan rail is lower than a stock block. Is this true? If so it could cause potential interference with the crossmember in a stock bodied application.

No problem in my 79 Camaro stock frame.
