Dont mean to highjack the thread . just a question that has been bothering me .
A properly built stroker will 'pull down the longest straight and off the corner' much stronger than a stock bottom end engine.

As a matter of fact, a properly built stroker will out-perform a 350ci at every point in the RPM range up to the PCM's 7000 (or so) RPM limit.

Been there, done that, no comparison.

Sure....If you could get/build it for the same price as a 383 stroker.

I'd have to, especially with the solid roller I would use.

If price is an issue, why not go with a 355 and than spray a 150 shot. If it were up to me, I would shed little expense building the right motor for my application. That would be mid/high end hp with enough torque to get me out of the hole clean.

I had these same thoughts six months ago, I chose the 383 all forged and balanced internals (Internally balanced). Lets not forget the cam, heads, TB and injectors to support the beast. I shook my head several times during the build, wondering what I was thinking when I decided to build the 383, but after the first start-up all the wondering was gone.

I say STROKE IT!

Price is always an issue with older car owners. And, who wants to carry a bottle [in an already starved for space C4] and pay for the juice....on a street car?
(I never considered NOS over a stroker.)

Build it to run hard/well on the streets in the most used rpm range(s).

Best place for a bottle would be in the compartment behind the passenger seat. I know a guy with a '93 that did just that and it fits perfect. Juice on a street car isn't bad. You just have to be sniper-like with it. Gets expensive having to fill the tank frequently

IMO, I would build the 383, if you use NOS on your 355 you should most likely rebuild the engine with forged internals to support thr bigger bang.

And if your going that far you might as well build a natural breathing 383 stroker. By the time you start adding all the parts and small things needed, the price won't be much different either way.

More cubes make more power, and it's all natural. IMO

A good thread a while back ... "383 with 113 heads or 355 with afr heads "
Not sure how to link it .
Im probably going the 355 route because of points and I have a steel 350 crank ,rods that are in decent shape .

And run the NOS ports under/inside the plenum. I've seen a nice trick setup like that too.
