BLOWN 302 VS. STROKED 396

SANDMAN771 · 09-06-2001, 10:59 PM

Thinkin about a new combo in my 91gt. So far I've come up with Pro charger on a 302 or buying a 351 Sportsman block & building a naturaly aspirated 396ci. Is anyone running a 396 on the street? If so, what is the best way to set one up for street use? Any HP or ET info would be helpful too.

If the price is somewhat even, I would definately build the bigger motor. (I'm not sure of your mechanical knowledge so excuse me if I sound too simplistic). A larger engine naturally puts out more torque without having to exert itself as much as the smaller one. A 502 c.i. big block can easily make 500 horsepower without a whole hell of a lot of trick parts. A 350 on the other hand can as well, but with more parts that lead to a shorter life, i.e: a larger, much less streetable cam, higher compression, etc. A 396 can make a hell of a lot of power and if you can do it naturally aspirated, then it will be under less strain than a smaller motor under the load of supercharger boost. I wish I was in your situation. I'm trying to come to terms with the fact that my 95GT runs like a turd. I just might have to supercharge it to get the level of performance I want. It doesn't take much to be an effective street killer; my '71 small block powered Chevelle was running high 11's. In street trims on BFG Drag Radials, I ran a 12.34 @ 111.5 mph spinning through first gear and grabbing in the middle of second. I never lost a street race. Goes to show, if you can just run 12's in street trim, you've got a great street car.

Go with the cubes. Either way, you'd have a fast car......but nothing feels like natural "ballsout" HP. Get the 396 in and add te blower to that later....that would be KILLER!

I've got a 93 LX with 12 to 1 396 stroker in my garage. Too bad it belongs to my buddy.

I don't consider it very streetable.

Heh, I'm not sure that's an entirely fair comparison to tell you the truth.

I think the 396 is going to cost a crapload more than the Pro Charger by the time you're done.

I wouldn't want a 396 just cause it's a Chev engine size. Always having people walk up talking about halfbreed, hehe. If it's any help to you, they'll probably run the same times on street tires. Getting out of the 12's without serious traction is hard to do.
