Solid roller cam on stock displacement motor?
Anyone running a solid roller cam with the stock bottom end? If so,
What are the typical cam specs?
What other modifications are needed? : longer push rods? (size), Fly cut pistons? Rockers?
What is done about the coil packs, valve covers etc...
What sort of lift is possible with stage 2 ported heads and flycut pistons?
Any help/info would be appreciated.
Robert :D

Here is a graph from last month before this motor was torn down again.
LGM 346 CID SR Dyno
The cam we are using is designed to peak at 7500RPM. However as it is peaking earlier we believe the intake manifold is a restriction. In the next couple months we will be testing some new intake manifolds as well - give us a call for details.
With the current package though if you shift at 7500RPM you will never drop below 450RWHP on a stick car.
I'll see if Lou can get in and post some more details of this package.

damn Jeremy, those are some nice numbers.
If you post in the internal engine section of LS1.com, you may get a better response. There are several people who are running that combo. They are ususally more than happy to share thier details.

I believe shaft rockers, springs, valves, and pushrods. I am very impressed with a local solid roller 346 drivability, and am waiting for dyno and track results. :yesnod:

Re: Solid roller cam on stock displacement motor? (RCswish)
That's me! I am maxed out on the size of solid cam that can go in without doing the bottom end. Cam is 640/640, 236/236, 112 lsa. 2.08/1.60 LS6 heads, T&D shaft rockers, .080 wall cc pushrods, 977 cc springs, roller lifters, etc. Pistons were flycut 100/1000th's (in the motor) with a cutting tool from Isky. See relocated coilpacks in my sig pics, they were fabricated from stock aluminum from Home Depot. :seeya

Re: Solid roller cam on stock displacement motor? (RCswish)
I have not been on a dyno yet. I plan on that in two weeks, along with some tweaking with LS1-Edit. I need to optimize my shift points, I'm hitting the rev limiter at the track going into 3rd. Anyway, with that, a line lock and a higher stall, I should be in the high 10's on the motor.
