Boost Question

[DEADLYSVT03]

can a 1991 5.0 handle 9 lbs of boost without a problem. i'm just worried that the block or the internals couldnt handle it. its a stock 302. i dont really wanna bore it out to a 306 so i was just wondering.

It will handle 9lbs no problem at all. just get a good tune for it to be safe and enjoy.:beer:

 

[Got Boost?]

yeah no problem at all, when i finally boost mine its gonna be running 10 lbs, i know a guy that ran 14 with no problem, but i woldnt suggest that much.

i have always heard on 5.0's that the block was the first thing to fail (at about 500rwhp) not the internals. does that hold true on the 93's? since ford dropped the forged pistons after 92.

i am aiming towards 450-475 at the wheels.. do you think this is a safe number for the block?

You will not see 450-475 with just 9psi, unless you have HCI already. A stock 5.0 with little to no mods will see o/a 330-350 with that amount of boost.

its gonna have trick flow twisted wedge heads, e303 cam, gt40 upper lower intake and bigger throttle body and mass air and all that other good stuff. i was just wondering if 450-475 is a nice number to aim for with the stock block
