A friend wants to do a very mild 351C 2v engine for 1972 Mustang. He has an Edelbrock performer intake, Edelbrock 600 carb, and will buy long tube headers. The rub is he wants to use the stock convertor and the stock 2.75:1 gear. He also wants to use the stock sled rocker valve train. Compression will likely end up at 9.1-9.3. On the low side I'm thinking something like 208/208@.050, .500/.500 on 110 LSA. On the high side I'm thinking 214/214@.050, .520/.520 on a 110 LSA. I would really like to get some input from everyone with mild 2V experience. Thanks, Chuck

You're in the ballpark. Probably couldn't tell the difference between either one of those. I'd split the durations though and depending on the lobes that are used, I'd tighten the lobe separation up. With that low of duration, it won't cause any problems, but it will help torque.

How much split do you think, 6-8 degrees? The stock convertor and 2.75 gear gives me concerns. Thanks, Chuck

Just gotta keep an eye on overlap and overlap won't get out of control with durations that low.

If I were doing it, I'd do 211/216 @ .050", 108 LSA, 104 ICL, .510"/.505".

Only 48 degrees of overlap on that one. It would sound like a stocker but would have more power.

Thanks Brent, I appreciate it. I've never tried to pick a cam for a car with a 2.75:1 gear, kind strange LOL. Chuck

You just gotta lower the power band enough so that the engine doesn't care if it's being lugged down.

204/214 would work well, ran a Blue Racer like that years back, nice street cam spec.
