lq9 oil pump functionality?
lq9 oil pump functionality? I'm wondering if it's possible to run the stock lq9 oil pump/timing chain set up with a cam swap. The cam is the TSP 233/239 in a bored .030 lq9 with ls3 heads. Basically just wondering how necessary it is to upgrade to a double chain/ported pump of some kind. The pump, timing chain/gear, and engine, only have about 3k on them since the rebuild.
It isn't totally necessary, just good insurance since everything is already apart, most people replace timing chain, lifters, oil pump...
IMO I would just because I'm upgrading.

Yeah, that's more less what I was thinking.. What would be a safe RPM range to keep the motor on with that set up? I was debating going with the ARP rod bolts for a little extra spin but I don't want to jeapordize breaking anything. I'm really in all honestly looking for 6500+ but not over 7000 rpm. The lifters, pump, chain, and gear were all replaced in the rebuild. But if needed for such revs, I'll just go ahead and upgrade to a ported pump and ls2 timing set up.
