Cam suggestions for LM7 with 862 heads Thanks for reading my post. I have an old project I have been working for years with my son. He is now off to college and I have the itch to get this thing running. The project I have is a 1973 Camaro RS. I have been a part of the NastyZ site for years and have gained a bunch of knowledge from that group.
I picked up a a 2002 LM7 with 862 heads and a 4L60E trans. I plan to do the swap this spring. I have been accumulating the parts needed for the swap. So far, F- body oil pan, LS6 intake with rails and injectors, timing chain, oil pump, gasket kit etc. As with most I am trying to keep the budget in mind because these swaps snow ball quickly. I will be changing the rear end gears to at least a 3.42 or maybe even 3.73. I have a line on a Z06 cam but the more I read the more I think I would be much happier with the aftermarket offerings. I have read that Elgin 1840-p or the SummitStage 3 Truck: SUM-8713: .545/.545 - 222/231 112+5 cam may be a nice option. I am looking for good all around cam. Suggestions from those that have a similar setup as I have?

Exactly why I am looking at my options. The Z06 cam was free but if I am going to go through the effort and the motor is sitting on a stand might as well stab something in there that is worthwhile. Any suggestions?

The car is 1973 Camaro RS/LT. She is a bit heavy at 3400Lbs. I assume the compression will be factory LM7 numbers. I don't have any power goals in mind. For conversation sake around 330HP+ is a good target. The car will never see the drag strip but would like to have get up and go. I have a 450RWHP 1986 Mustang to thrash if needed. I have not purchased the stall as I understand that I need to match the cam and the stall. The price of the Summit cams are pretty reasonable and fit my budget.

I currently running the Pypes SS exhaust with x-pipe. I plan to use that with this swap. I am going to give Summit a call and get some suggestions from them on a cam. i will let you know what they recommend for my application.

Trying to avoid head work if possible. At some point when the motor needs to be rebuilt I may look into some new heads that flow better. For now I am going to swap the cam, intake, TB, electric fan, and a torque converter.
