Thread: Replacement engines are they inferior

Thank you I thought so also. Let me give you some real life examples. I had a 1971 340 Duster and 2 Mopars with 360 a 1975 Roadrunner and a 1978 Magnum. Though the Duster was a stick and that gave it a little advantage off the line it was far quicker than both of them .Well I changed almost everything. cam,carb,intake, distributor, low 3:54 gears in one 3:90 in other,headers,head work,etc... on the 360's. And I eventually got them both to run quicker than Duster but why did it cost so much to do it?

Next example my friend had a 1967 Polara with a 383 Magnum I had a 1976 Cordoba with 400/4 barrel and dual exhaust. He kicked my ass for almost a year,before I could beat him at a cost of 3,500.. Why?
