305 to 335 stroker kit?
I was wondering if anybody had put or knows of anybody with a stroker kit in a vortec 305(not TBI) in a 97 GMC Sierra? I kno half the people on here will say its dumb to do anything that extensive to a 305 because they are "weak", but i would like to surprise a few 350 and other V8 owners wen i pop my hood and show its really a 305 that just spanked them. If u have any good suggestions i would really like to kno... thank you
305 block looks the same as a 350. Just build a 383 and have fun.

yea that is true, 350 is good. how much would it cost to buy a used 350, stroke it and build it up?(as cheap as possible) Also where could i get a good tune on the PCM to change to the 350?

305 just doesn't have the bore needed to make power. the only upside to a small bore is you can run some more boost- but the heads and pistons aren't condusive to boost like the small bore 4.6 ford engine.
Cliff notes: 305 is a better secondary e-brake than powertrain.

You'd be much better off building a 383 or a 377. I once thought of hopping up a 305 until I learned it was just a waste of time and money. For the money you spend building up that 305 with a stroker kit you could spend a little more and get a LOT more potential with a 383 or something. Trust me, the 305 to a 335 just isn't practical. I agree with Hog, get a crate motor. Just my opinion....

Just FYI, TBI's don't make good power with modifications unti you tune it properly. TBI's seem to idle rough/stall and don't make expected HP at WOT, especially cam swaps are not even close until it's tuned. If you need help learning to tune TBI's, I suggest you hang out on the third gen F-body site thirdgen.org. The forum members there have done a LOT of TBI tuning, including cams/strokers/etc.
