LS1-7 questions ... So,I have an LS1( block ) bored out to a 4.155 with a 4.125 stroke. Has a custom cam ( specs unknown) and utilizes 7.800 pushrod( LS7 stock length) , uses LS7 rockers with a trunion kit. It also has LS7 heads. My question here is ,can I throw in a LS7 BTR Stage 3 or 4 cam ? They use same pushrod length and my valve reliefs are -22cc., and the piston comes up past the deck 0.005 .
many input is appreciated. As it seems , I already have a violent cam. Can I send it in to a reputable shop to have the specs revealed?
thanks in advance.

I'm assuming when you say bored you mean resleeved? You can't bore an LS1 block. Anyways, the ls1 and ls7 style cams are not interchangeable unless you get the ls2 timing chain and frt cover and get a ls1-ls2 cam sensor extension harness.
