3.2SS cam grind help

[johnnyutah]

I am looking to get some cam experts to weigh in on a new cam grind for my 3.2SS engine.

I bought this engine part way through a build for a race car and finished it for my 1970 RSR street/DE car 4 years ago and have enjoyed it on and of the track since. I have since broken a valve spring and had to pull it apart and since i am now vintage racing a 914 i no longer use this car that much on the track. While it is apart i would like to re-grind it to something more street friendly.

The current build was based on a big port 3.0 using 98mm JE pistons with a 10.5 to 1 CR. PMO 46mm throttle bodies and Electromotive tech3r EFI. Cam is way too big at GE80 for what i use the car for. As i live in Toronto and often drive when it is pretty cold heat is a must so i am running SSI's and a M&K 2 in and 2 out sport muffler. As you can see by the dyno this exhaust is very restrictive for this cam and there is no power beyond 6800 RPM. With this cam there is no power until at least 5000 either and since i have the motor open i would like to send the cam to be reground to something more user friendly or purchase a new cam. I know i should be able to get more HP than the 240 at the wheels with a more open exhaust but i would like to keep this setup and hope for more low end torque and power before 5000 rpm for the street.

I would grateful to hear what the Pelican cam and engine experts might suggest.

I realize i posted this in the wrong forum. Moderators can you please tell me how to move this to the engine build forum?
