Does anyone know how much HP the stock bottom end of a 1991 F-Body 305 can handle?

I was told 400 HP MAX.

Thanks.

 

same as a comprable year 350...

 

A stock 305 bottom end will never see 400 HP.

 

And where's your proof to this, i doubt itll survive to long, but it has been done, tons of time. If you really want me to drag up all these different peoples different kinds of power adders and show you the power they are making, i will.

Im not saying its smart to push it to this level, but it can be done, chances are though, its not going to last.

 

Intersting since my 305 has 2 blowers and 12 psi... on a stock low end. no bang.... yet..

 

OK

SATURN5,

Lets talk.

My 305 was just dynoed at 343 RWHP. The 400 HP I was asking about is RWHP.

I was just advised by Robert Kennedy who does dyno work, superchargers, nitrous, etc. to stay where I am at now. That I am at the safe limit for a bottom end.

Said definitely stay away from nitrous, even a 35 HP shot.

I know Willie is going to be running 20 psi boost, but he has at least forged pistons.

I am all stock inside.

Advise???

 

the only thing i would put a 35 shot on would be a motorcycle. what good is that?
