I have a pair of Edelbrock Performer RPM Big Block heads and associated valvetrain components for sale as a package as I stepped up to Trick Flows. Everything has VERY little time on it. Basically dyno time and moving the car back and forth between shops for chassis and suspension work, but that's another story!
The heads have a port match and some minor bowl work. No porting has been done. They have 84cc chambers and started as bare castings (6091). They were assembled with Edelbrock valves, Comp 929-16 springs at 1.880" installed height with 148# on the seat and 432# open at 1.230", good for .650" lift. They have Comp 741-16, steel retainers and Comp 611-16 10 degree locks.
The cam is a Comp Magnum solid roller part #23-742-9. The cam card is posted here.
The pushrods are Manley's that are 8.550" long, 3/8" diameter .080 wall ball/ball pieces.
Head bolts are ARP and the rockers are, yeah, I know, Pro Comp/Speedmaster stainless 1.5 ratio. Hey, they survived the dyno and the motor made 638hp @ 5600 and 671 ftlb @ 4400 on a fat tune with an a/f ratio of 11.6. This was a 512 stroker.
I'd like $2500/shipped for everything. It's a good, solid combo with everything you need to go roller minus the lifters. I have cleaned all of the parts, but I recommend another thorough cleaning before putting anything on an engine and you will have to re-set the side clearance on the rockers again as I didn't pay attention to which shims came off what head when I took them apart. I just mocked everything up for the pics below. Thanks for looking!
I have quite a few pics, so They'll be in two threads.
Sorry about the sideways and upside down pics! They keep uploading that way.
