Aftermarket Cams

[Alexandros]

Wondering if anyone has installed the L & M camshafts and dynoed the car. I read online of a GT350 owner who installed Frankenstein Engineering ported heads, L & M camshafts and lost power. He then sold the car. There is room still left in the ports for more CFM, as well as more airflow with a ported intake manifold. Thought is it becomes an octane thirsty situation above 93 octane to fuel the added air flow with long tube headers and a tune. L & M Mike advises more power to be made with the camshafts and ported heads. Hoping someone chimes in and has an update.

Todd Warren Cams (Facebook) inquired about three months ago about cams hinting army Comp Cams doing something.

I found the thread by 11secls1. And he actually used ported heads with stock cams and intake as was 91 octane and 514rwhp. I can call Todd and see what he says.

How much do you think is maximum compression on 93 octane? 12:1, 12.5:1, 13:1, 13.5:1.

6% more hp for every point of compression.

3%

Yes 3-4% it seems. So do you think 13:1, 13.5:1 or 14:1 on 93 octane is doable?

If you are going to build a max effort engine, and not use methanol injection or E85. How much compression on pump gas 93 can one safely run?
