I know alot of you guys have played with the LT1s so Id like to know the best way to go in rebuilding for decent power without just guessing what parts to buy.

I already have a stock block with stock alum heads. I could replace the one piston that ate a valve and put my new to me stock heads on and call it a day but Im thinking since i have all winter and a daily driver I would like to try to get 350-400hp out of it while still keeping it reliable and buying a bunch of upgrades to help the chasis handle to much power. I also dont want to spend a bunch of money to have the baddest car on the street. I have nothing to prove to anyone and if i really want to go fast Ill just grab the bike.

So after knowing that

what pistons/rods would you suggest
should I replace the crank
what valves/rockers
should I bother with shorty headers since ive heard the stock manifolds flow decent
throtlebody/injectors

Ive also considered swapping in 3.73s to replace the 3.42s

The car is a 95 Formula convertible with the M6
