    idk how much power i make, but i spray a 200 on mine, i did change the connecting rod bolts, and now run an 80e trans, i had a built 60e and its still working i sold it to a guy thats putting it in a 69 camaro, like tyler said though anything over a 150 shot and the tune needs to be pretty good, you could run a 100 shot and be pretty safe but, theres always the chance that something will go out especially with stock parts, your tranny or rear end will prolly go first, if youre wanting to go fast youre gonna break stuff its just a matter of when, unless you upgrade pretty much everything.
