The camshaft, are you giving the numbers factoring in the 1.6 ratio rockers or is that the numbers with the stock 1.5's?

those are 1.5 ratio lift #'s IIRC...with 1.6's it'll be .459/.480
I agree, sell the lifters, just pick up a set of normal lifters and be done with it.
what's you're installed height? to get 200 lbs seat pressure, you'll probably need double or triple springs.
for the $$ you spent on the schubecks you coulda had a nice retrofit roller cam and roller lifters. or you coulda started with an '85 up block and used OEM roller lifters....
one other question; did schubeck make hydraulic lifters? I thought they only made solids....I wouldn't run a solid lifter on a hydraulic cam.
