True dat.... or just GO!
Have fun with what you got, push it as far as it will go and build a REAL engine when it crashes.
I'll probably be singing a different tune if mine blows on me.

This while I stockpile $$$$ for a larger forged engine with a bigger sc... right now I'm thinking F series Procharger with cogs.
I want 1000 hp.
I don't know why. It's really dumb. But... whadayagunnado?
I also want a sheet metal intake. I think they're really hairy.
Taking some time to get the $$ together might mean I'll come to my senses before I do it. Hell.... I think what I've got now is scary-fast!
But.... if I'm gunna do it I'd better git'r done before I get too old to drive the dammed thing.

I've been running 12lbs and a 75 shot for a while. I don't go WOT everyday or hit the nitrous everyday for that matter but I've made a good share of track runs with no signs of trouble.
I think if you have everything in line, parts, tune, you can make some big power with a 5.3 reliably.

Thanks everyone, I think for now I will just get a performabuilt or FLT next week , get a good tune maybe add 2 psi of boost and enjoy it until it breaks and save $$$ for a bigger motor and bigger blower.
