Re: cam help ?? your recommendation
I noticed that you picked the most powerful hydraulic cam ever designed! Surfing the bottom of the page in a cam catalog will get you the most radical cam. This yields a radical cam, that will not be street friendly.
The Lunati cam catalog states that they (I believe it was designed by UD Harold) was "Designed for Very Hot street/bracket race applications" This cam requires a minimum of 10.5:1 compression, 4.11 gearing and a 3,500 RPM stall converter!. Do you have a 3,500 RPM stall converter now?
Cam Specifications according to the cam card are:
Duration at 0.050" of Valve lift (Int/Exh): 241°/249°
Gross Valve Lift at the Valve with a 1.5:1 Rocker (Int/Exh): 0.525"/0.546"
RPM Range: 2500-6600
You are going in the right direction with this cam, in that it has more valve lift. You want to maximize the cam lift, and minimize the duration, and to widen the LSA for a street driven cam to obtain a good cam. If you want a race car for your trailer you want a solid roller that will spin your 355 up to a 8,600 RPM shift point, a 5,400 RPM torque converter launching off your trans brake, and 5.38 rear gears. You also need to pump up the compression. In any case your quench is on the tight side so be very, very carful of valve to piston interference at 10° before TDC.
