There are a LOT of variables, as I'm sure you know.

But, there are quite a few 400 & 455 powered Stockers running mid to high 10's, with unported iron heads, iron intake, 750 Q-jet, & low lift flat tappet cam.

Several Super Stockers have run 9's, with iron heads, & 750 Q-jet. Quite a few have run 9's with the alum head 428 & 750 Q-jet.

These are obviously drag only cars. So, if you are trying to do it with a heavy car, and trying to keep it streetable, that will take a little more power. More cubes make it easier. Can build a stock block engine to around 500 cubes. If your budget will allow, an aftermarket block will allow well over 500 cubes. 

So, basically, your budget is the biggest ET limiter.

I'm not interested in an aftermarket block. If a factory block can't handle the task it might be time to go LS.

Tens on motor nines or better on spray. That's what it takes to keep up with the Mustangs.

I can't say exactly what it would take to get your car to the performance level you want.

My engine guy built a factory block 4.5" stroker, with KRE High Port heads, a solid roller cam, a Northwind intake, & a Dominator carb, on E85. It made 755hp @ 5900 rpm, and around 700 peak torque.

But, if you wanna go 10's with iron heads, a Q-jet, a HFT cam, & 92 octane pump gas, THAT will take a little more planning.

If you wanna talk to some guys with factory block 10 sec cars, go to the PY forum.

Most low budget guys who wanna go fast have always gone with Chevy power. Chevy parts have always been cheaper, because of mass production of aftermarket parts. When it comes to price per horsepower, it's not even close--no contest.

So, if your budget won't build a high power Pontiac engine, you'll just have to switch, I suppose. May as well go with a light Chevy body too. I've read that every 100lbs = about 1/10 of a sec in ET. There is an alum head 428 Pontiac powered Cobalt that has gone high 8's. It's the quickest Pontiac powered Super Stocker I know of. Lighter is quicker.

I've been thinking about a 4.5 crank. I've got a 4.25 in there right now. I'd need a new set of pistons but the rods would still work.

The chassis gets better all the time. It'll dead hook at the track and I can spray it into the 10s.
