318 camshaft swap 260 duration

Toolman,None at all. It has the stock converter it was born with.I have the idle set at 800 in park. Very pleased with how well it runs.Future plans if I keep the car will be Borgeson power steering and A/C.My thought was this cam with A/C might not do well but I feel it will be fine.My E-58 360 at idle with the air on in a 79 300 idled really ruff.I blame it on the RV-2 Mopar compressor though.
As I said earlier it idles in gear fine and drives well.Very pleased with what is known as a cheap "Jegs" cam.My only complaint is with the Jegs and other Summit small block Mopar cams (had a few over the years)is lifter bleed down.Gets that clickety-clack at start when it sits for a few days.
