So I blew up my LS1 with 80k miles. I purchased a LQ4 from a 04 chev for $500 bucks with 70k on it.

My questions are: can I just add a ls6 cam and springs?

Should I put the heads off of my ls1 on the lq4? The heads on the ls1 say "843" I think. I do have a complete pair of 317 heads as well.

I will be doing the oil pan/accesory swap.

Thank you for you help!

 

The heads on the LQ4 are far superior to your LS1 heads. You should drop in the LQ4 as it is. It will make a good amount more power under the curve than your LS1.
