I know I will have it on pump gas and im definitely going to lower the cr to 9:1 and probably keep it at 8psi and I know everything the is forced induction will need a tune so im not gonna be an asshat about driving it til I tune it

That's why it was only an "IF" situation-I never discounted the importance of proper tuning...only wanted to the OP to be aware that possibility exists...that's all
That sucks about your meltdown though...what was the "rule of thumb" you're referring to?
A few guys have already touched on this, but I think it isn't quite getting through: boost pressure doesn't mean 
. Boost pressure is just a measure of how much air you are trying to push into an engine and how much resistance it is encountering on the way in. It has very little to do with how much stress the engine block sees.
Engine block stress is more closely related to rpm, torque production (those two together = HP, by the way), engine balance, detonation, stuff like that. Boost pressure can lead to some of those things, but it is not the determining factor alone.

LMFAO!!!!
did anyone provide you with the necessary info needed to help you with this build? or did they just repeat like parrots the ''HP level of a STOCK 302 BLOCK''? witch is spread all over this ENET. like a disease witch that info is also false. i guess its not 100% false i guess its rule of thumb for clueless ppl.
seems everyone likes to repeat stuff around here.. or come up with their own analogy. lol
Brosef, I dunno what hole you crawled out of, but calling people out on here isn't gonna fly for very long.#

You are "one of them", take your ignorant mouth somewhere else, no one likes a c0ckee enthusiast... Which you seem to have done when you posted about your boosted racecar....
Not gonna warn you again. Get along, or you're gone! You're not the be all, end all authority (as much as you'd like to think you are) on everything automotive. Feel free to offer advice, but be objective and keep the snide remarks to yourself. You revving people up on here for the sake of stroking your ego and attempting to prove to them how much smarter you think you are is not going to win you any support and certinly won't end in your favour!
let me add since i didnt see it posted before...
boost pressure is a measure of how much restriction you have on the motor (go with me here you'll get the point at the end)
if you cant flow out the exhaust what your forcing down the intake the boost will go up. power on the other hand will not.
if you can keep thing balanced you'll make more power on less boost.

Here's when it happened, and I still drove it 2.5 hours home. Notice I didn't miss any shifts and I never revved it past about 5900. Now....when you can chase down a Lotus Elise in a full-interior A/C-and-all foxbody Mustang with a stock K-member and quadrabind suspension like mine had at the time, while running street tires, then maybe you can tell us something about how to drive. Until then, GFY...."Mang".
