BUT...How hot is too hot? If your compression is low enough, your timing isn't too retarded and you're not running the fuel too lean, you will probably be okay at 5psi

You mean with retarded timing right? Banks sells twin turbo SBC crate motors that put out over 1000hp non-intercooled. And they claim about 600hp on pump gas, with a stock 350. And I've seen alot of non-intercooled Buicks that run in the 10s. It can be done, but it'll really help too keep your motor from takin a ---- on you.

Re:i have no intercooler (how bad is that?)

i ran 15psi unintercooled. its all about tuning and not getting greedy with the timing. good thing leed spent the time tuning bbka's car ;). max timing i believe was at 19 degree's and i regapped my plugs to .028. no detonation. even in california weather :o
