That’s on you. Evidently you don’t optimize anything, you just change for change sake.
For the VAST majority of everyone else out there, a custom converter is as important as a custom cam. Do them both.
My friend just had a local torque converter company do him a converter. You couldn’t even drive the car.
600 buck and a bunch of extra, needless work he now has a converter than add took a car that was worthless to a car that turns heads.
I will never understand why this is ever in question. Unless you are doing dead stock stuff, you should get a custom cam and converter.
I tell people don’t be penny wise and pound foolish
