I recently bought an LS1 long block for a swapping into a 3rd gen. I plan on putting 317 heads on it and boosting it. Then I started thinking...

Should I boost this thing or "save" it since it is a 5.7 and find a 5.3/6.0 and risk blowing that up instead? Not saying Imma blow it up. I might. You never know.

 

You already have the ls1 so might as well just use that. I have a friend running a stock ls1 with 317 heads and put 628 to the wheel. He has been running it for years now with out an issue

 

Use it.
