who has lost a motor due to oiling issues above 6500 rpm in N/a application?
considering its a stroker motor good forged bottom end ect...

i want to rev past or at the very minimum 7000rpm. i have a stock oil pan and just ported oil pump. im getting alot of feed back to go dry sump, while i'd love to just call and start discussing details about putting a kit together with someone, the cost of a dry sump will make the car stay down for this season. DONT want to do that.

am i being realistic in thinking my motor will be fine spinning to 7000rpm and live?

or should i stick it out for a dry sump setup which will all be new to me and take forever to get together.

When I had my 2002 ss head and cam car i would rev to 7800 rpm and never had a oil problem. When i did the head and cam set up i put a slp oil pump in it and never had a problem.

Hopefully I dont get flamed for this but, just earlier this week while at the GM Training College in Chicago I was told by an instructor that ANY of the ls series motors will handle 9000 rpm with stock bottom end components. I would like to know how true this statement is. Any confirmations?

no pro here, but I havent heard of many stop rod bolts in these motors holding up past 6500-6800 rpm.

stock rod bolts i wont trust over 6k. my bottom end exploded on start up so tha t should tell you something about how weak some of the lower end is

my application is not a stock bottom end but it still a stock wet sump ls1 oiling system. does anyone else think its not a good idea to spin my built bottom end to 7000 with the wet sump stock oil pan ect..

i heard 02+ LS1/LS6 rod bolts were good to 6900rpm and 97-01 rod bolts were good to 6500rpm

I started with a stock 23K mile '99 LS1 Fbody engine and installed Katech rod bolts, ported LS6 oil pump, LS2 Tchain, TSP 233/239 cam, AFR 205's, LS6 intake, ported TB and headers and set my redline to 7100rpm.

When roadracing I do overfill my oil pan to 7quarts. On the street I put in 6 quarts.

Been spinnig it to 7K for 20K miles with no signs of wear/tear. The rod bolts I'm sure are the key. As long as your assembly is balanced you should be fine.

You can install an Accusump if you are worried about poor oiling conditions.

You should be ok. for wet vs dry I don't think it will really matter in a drag race type scenario. I don't think it's so much how high your peak rpm is. but for how long you have the motor at a high rpm. It I was going to do some all out road racing or maybe very involved(built susp. etc..) auto-x. where I was going to see a considerable time above 5 or maybe 6k rpm and high forward and side gravitational loads then I would consider fry sump. But just to spin it to 7000 then in a drag race then no. For what it is worth I have a 107k motor with arp rod bolts, and ls6 pump. I have my limiter at 7200. I've had it like this for 6k miles now with no problems.

My limiter is set at 8000 and I'm planning on shifting around 7600. I usually try to add 1/2 quart extra or so if I know I"m gonna be at the track. I'm not afraid to take the r's that high but I don't stay up there any longer then I have to.
