I have all the modds in the sig and impala head gaskets, and other misc. crap do you think with the 125 shot I would be pushing the stock bottom to the limit. I don't want to us it if its going to cost me me motor. Also have a a inline fuel pump to.

 

I seriously doubt it. You don't have any type of numbers like 1/4 mi times or dyno numbers but I would assume you are making somewhere close to 350rwhp N/A give or take a few so you should be fine with a 125 shot. My car put down 425rwhp on a 125 shot and I have run it with a 150 quite a few times w/o any probs. Ther is a guy on here running 9's in the 1/4 with a stock bottom end LT1 and an Impy running a 200shot and 11's with a a stock shortblock also. Later

 

Cool I fill my bottle and get my purge tommorrow.

 

100% stock longblock here and im hitting it with a 175 shot. Ran last year and a half with a 150.

 

Who runs 9's on a stock shortblock?
