OK gang, I haven't built a motor in 30 years. And all the motors I built back then were for street/strip. I always ran Mopar Performance cams. Now I have a 1973 340 in a Road Runner I'm currently restoring and I plan on using it for cruising and possible road trips. This car won't be visiting the strip. Stock bore, stock compression ratio, stock heads. I am looking for a cam that will have good drivability and idle as well as lower RPM torque. I see Melling has a stock grind replacement cam (SPD-22) with the following specs:
Exhaust Duration - 289 deg
Intake Duration - 279 deg
Exhaust Duration at .050 Lift - 220 deg
Exhaust Valve Lift - .444
Intake Duration at .050 Lift - 209 deg
Intake Valve Lift - .429
Lobe Separation - not listed
They also offer a cam (MTD-1) with the following specs:
Exhaust Duration - 288 deg
Intake Duration - 278 deg
Exhaust Duration at .050 Lift - 214 deg
Exhaust Valve Lift - .443
Intake Duration at .050 Lift - 204 deg
Intake Valve Lift - .421
Lobe Separation - 112 deg
Your thoughts on if their MTD-1 (classified by Melling as a torque towing camshaft) would have any advantage over the stock cam for my intended usage? Or any other recommendations for a good cam? I have read there seems to be lots of quality issues lately. Thanks!
