True! The balance issue is when you move away from what the factory did. It will add costs going from external to internal.
The Magnum has a different external balance than the LA 360 external balance. The good news is B&M has a SFI flex plate that handles both engines.
I don’t know how big of a cam you want to run but Blue Print does offer 2 different cams with the engines. Go to our Print (.com) One is a good attested and the other is about 10*’s more. For a nice street stripper that isn’t to danm big to drive around on.
Mswapping out a cammis no biggie. Re sell the. p cam to off set costs if not simply break even. (Or better yet, profit!)
Oh, arthritis, yes I got it, I know it.
