It would be good to know what you intend to do with your car; race, daily driver, long trips? (Don't expect anybody to necessarily remember your past posts on this....)
- Do you want tire squealing, or economy and torque?
- Carb type; 1bbl, 2, bbl, or 4 bbl?
- Trans type?
This cam is pretty similar to one sold by Doug Dutra (Doctor Dodge on
www.slantsix.org) but supposedly his has a bit different lobe profile. I put one in my all stock 1962 /6 in a B-bodies '62 Dart. It does very well in the low and mid ranges and seems to pull this heavier Dart up the Appalachian mountains just fine with a manual 3-speed and a 1 BBL carb and no valve mods, just an .050" head mill. I can tell the idle is just a bit rougher than stock but still smooth.
Doug will set the LSA on the cam differently for a 1 BBL vs 2 BBL. The Comp Cams unit has 4 degrees advance ground in, so that is good. If you don't/can't spec that with Doug, you'll have to monkey with cam buttons to set advance in the cam. So that is a plus for the Comp Cams unit.
You can use Sealed Power VS510 valve springs up to .435 or .440 lift; the pix of the Comp Cams kit looks like duals which is not really needed. Someone else did some /6 valve spring research on this level of lift, so maybe they will chime in.
What REALLY bothers me on this particular Comp Cams kit is that the pix is for a V8!!! So who knows what you are going to be getting!! Caveat emptor.....
