Well, my buddy is getting a 383 stroker put together for his 71 camaro. Calculated compression is 10.7 dynamic 8.8 and cranking compression 234. Iron head, tunnel ram, 4 speed, 3.73 gears. Wants to run on pump gas on the street. I am concerned about it rattling with such high compression. The tunnel ram will help by drawing cool air into the motor, but I am unsure if it will be enough. What to I do? Oh, double hump heads, hardened seats, stainless valves, solid flat tap pet cam, cam is still being debated at the moment. I just don't want a non running piece of sh!t that I have to try and tune. What are your recommendations?
