92_RS_305

What all will I need if I stroke my 305? What are the parts & specifications I will have to have? Also, how much will it cost to get all of this done? And what kind of horsepower will I be looking at after it's complete?

These questions should be asked in 3rd Gen Tech, moving there.
Thanks.

It is really worth it? Can the 335 with it's small bore even compete with a 350? I know a friend of mine ran his stock '89 Formula against a '90 Camaro w/ a 305 w/ larger cam and head work. He killed that 305.

Not trying to flame, just curious. If so, great. 305 engines are easy to come by.

No. The bore/stroke ratio sucks, and you're still 15 cubic inches behind, not to mention it costs MORE to have this disadvantage. For what a 350 block costs, I'll never understand why somebody would stroke a 305. It costs more and you wind up with a lot less.

if i was you i wouldnt waste your time on a 305 now if you get a 350 then we'll talk!

i don't know if it is wasting time on a 305, b/c there is a guy on here i think with an RS with a 305 or stroked 305 that runs 11's on nitrous, but the cheapest route would be to pick up a 350.

the 305 is low compression . Put on two t3 turbos used and rebuilt. Have someone weld on flanges to your stock manifolds after you swaped sides and fliped them. do al teh other things you need for turbos like oil, fuel and intake lines. Set the boost around 8 lbs and you will have much more power than any stroked 305 and more power and ceaper than swaping for a rebuilt 350.

On Nitrous is the key phrase here That guy "baddest305" I believe has a great setup, however I'm sure he would agree that the 305 isn't the best platform to work with. Look at his combination:

305 cubes
150 shot of nitrous oxide
decent aftermarket dart 305 heads
bigger cam, added duration
higher reving intake and carb
1-3/4" headers + True duals
TH350 trans
3500rpm torque converter
Weight reduction here and there (Tubular front end), Hood, seats
ET Streets and Skinny's
Lightweight rims
Drag shocks and springs
More suspension mods

This guy has made his 305 combo extremely efficient and fun for damn sure but imagine is he had 45 or more cubic inches, larger valve heads and a bigger bore to work with. Ooooo now that's fun I'm chasing this guys times with my own little 305 so wish me luck! It MIGHT be cheaper to do a 350 but even if it cost a slight margin more it's well worth the gains. Goodluck out there everyone!
