How tight to set solid lifters
rumblefish, I did play with the lash settings with the 590 cam, don't know if it was my combo or or just the 590 cam, but I don't remember it making any difference in the performance of the engine. I do remember that that after playing with the lash settings that I ended up tightening up the exhaust lash to the same(.028) as the intake lash just to make lashing the valves a little easier and to quiet it down a little.
I will say that cam hated valve springs, Oh man did the cam beat up valve springs. that 590 is one hell of a cam though.
I will admit that I replaced the MP 590 cam with a Cam Motion Roller cam with 263/270 @ .050 642/629 lift. and the car didn't run any quicker, but the car did picked up 1 mph. this was in a 372 inch engine in an 1980 Mirada.
