I have a dirt modified and have ran traditional small blocks my whole life. I decided to go to an ls engine this year. here is what I have. I have a 408 with compstar crank and compstar h beam rods diamond pistons in a LQ9 block. My question is I have heard there may be some oiling issues with these type blocks at high rpm. I will be running over 7000 rpm ALL the time. I was wondering If I could get someone with more experience to help me out on what needs done. When it is finished it will have solid roller valvetrain with ls3 heads thanks in addvance like I said Im completly new to these type engines any help would be great!

 

I'm curious myself what exactly it takes for sustained high rpm operation of these engines. Bump for an answer.

 

A great oil pump is required!! Shumann oil pumps by Tim at the car shop I'd who I would recommend... Google them... they have awesome products that get used by the big boys. I got one on my car and I love it!!
