How do I pick a TC??

Then I would go with something like a 3500-4200 and probably lean towards the 4200. You need to CALL a good converter company, Frank Lupo, Precision of New Hampton, PTC, whomever and tell them that's what you want but you want it tight because it's a street car. That way you can cruise around without converter slippage of the 1970s and still flash high when you do a launch against the converter. A good converter won't be 250 bucks, either. If you don't get into the 400-600 range, you're likely not getting a good one.
Right on! I was hoping to go this route but wasn’t sure they would have to know cam specs?
