Thanks Brent for your reply.
Jdean, Hopkinton! too bad you still don't live there,I'll be looking for some Cobra guys this spring to chat with and do a little riding.
Yes the cam has a lopey idle, I forgot to mention a 110.5 centerline and 70* overlap, CompCam roller rockers, Edlebrock performer RPM and a 650 speed demon. It took me some carb tuning to get the idle mixture to respond and still it wasn't great. ( I had to revert back to my drag racing days
). I'm using ported vacuum right now. No cooling or off idle problems and it pulls like a bandit. I'm guessing about 450fwhp, I don't know anything more about the engine internals and that bugs me. I can't believe the original owner didn't care to know every little detail about this car. It is well made and still in perfect shape, only 3000 miles on it.
