we got billet cranks and rods, we have a spread port design head out there, give us some cubic inch, dammit, the way it is now, you have all the bottom end, and nothing to move the AIR, we need bigger Pistons, MORE BORE!!!

these days a 4.5 bore is small, i own two chevy's a4.5/540 and a 4.6/555, but i still love my pontiac, just wish i could build a pontiac without so much stroke and a lot of bore, to move the AIR. both of those motors make over 900 plus on the motor, with smaller strokes. 4.25 stroke,4.6 bore,W/355 cfm heads, =946 hp. i want my pontiac to do the same!!!

A pontiac block with the bore spacing change like that would mean a total re-design of cylinder heads and everything else. At that point it would not be considered a pontiac and would cost millions to build. We are stuck with what we got.

With all do respect to MB125, but his reply is the very reason why the Pontiac will NEVER be able to be truely advanced to the level of Ford and Chevy. Our market is dominated by too many bracket racers, car show cruisers, and purists.

I pearsonally would love to see 6 bolt heads, bigger b.s. blocks, ect... But then again, like Lou said, they have a hard enough time selling what's already available.

Default Got Cubic Money????

Why 738 CI?
Go get a Turbo Allison V-1710 out of a WWII fighter Plane and build the car light.You already got 1500 horse , overhead cams,fully forged internals,dry sump oiling , dual magnetos and lots of other cool stuff before you hot rod it.


NHRA Pro Stock ,Top Fuel & Funny Car engines are limited to 500 cubic inches.

Many Nostalgia Top Fuel cars are running with less displacement than that.

Stock and Super Stock are limited to whatever displacement + allowable stock service over bores for the engine.
No stroke changes.


Only place those huge displacement "mountain motors" can be run (besides the street) are in "no rules " bracket cars, special heads up"Outlaw" classes , boats and IHRA Pro Stock .

Look at the cost of a full on Kasse , Leonard or Reher Morrison engine.
That's a lot of paychecks and groceries for most folks.

The IA II block already can easily achieve 500" the only limiting factor had been cylinder heads.
You make 700" of pump NA you have to have a head that can feed it or you are looking for power adders.
Mega dollars.
If that is what you want & need go for it.

I want to see someone get a Pontiac there on or under the 500 C.I. limit.

A Tall deck IA2 or IA1 If it can fit the 5.25 stroke crank could go to 638cid or 608 with 5.00 stroke and 7" plus rod length, Couple that with Max CV1's Or Tigers and a Sheet metal dual dominator intake and you could make some power NA, Heads would still be a bit small though
