Hoping Lunati can supply me with a roller version similar in specs to the FT 10120703 to put in my new 355. from the engine by increasing the effective lift of the camshaft. I selected the slightly milder cam, the 10120703 and haven't second guessed my decision with 8k miles on it. So a weight reduction of 10 grams could theoretically add 350 to 400 more rpm to the. PISTONS - Must be flat top and have 4 valve. Fyi, Lunati said the 10120703 or 10120704 would work, for me. -Intake- Performer 2101 intake No b owtie, -Carburetor Box stock Holley 600 1850 carb or Holley 500 4412 with 1 max. Your best bet is to fill out a cam recommendation card with several cam companies to see what you need to meet your expectations. Very pleased, pulls hard to 6800rpm with the heads, intake, carb and exhaust I have and idles at 750 rpm with 14" of vacuum. Currently I have a Lunati Voodoo 10120703 hydraulic flat tappet. That cam ground on a 110 or 112 LSA will be more flexible to drive. Though a narrow LSA may produce more peak power it does so by sacrificing a wider torque curve which gets you down the road. Do not know of anyone who has run the "midnight special" but it may not pull enough vacuum to operate vacuum assist power brakes given the 106 LSA.
I will tell you it is far better to under cam than over cam. Cam choice is dependent on many factors, car weight, intended usage, compression, heads, intake and exhaust run, rear gears, trans (auto or manual) just to name a few.
