A friend has a 1970 383 he wants to build for his 70 Plymouth Satellite. He has factory intake with 906 heads and basically 9.1 compression. A friend sold him a Mopar Performance 440 six pack cam with 268/284 duration ( 228/ 241 @ .050) and 450/458 lift. When He took the motor to the shop, the engine builder told him he actually had an RV cam with 212/ 226@ 050 duration and 450/458 lift. He was very disappointed. The Engine builder got him a Comp Cams 21-006-5 Cam with 267/284 Duration( 227/ 241 @.050) with 486/ 473 lift. Will the extra lift cause the engine to be less streetable? Which cam is better for His otherwise stock application? Appreciate Your guidance on this. He is running a 750 cfm carb 727 b torqueflite auto trans, a 3.55 rear end and factory exhaust. Appreciate Your guidance on this.
