I wrote down the numbers that were on my block/crank when I was in the engine a few years back. Well I want to add a 142 weiand blower and was wondering if the heads/crank I have are good enough .... or if I should upgrade (its all stock, but GOOD stock parts). How do I find my compression ratio....the pistons have been in there for 20 years, lol ( they have 4 divots on the top ).
*** #4577 (front ) and CMT (rear ) of crank = Forged Steel, SMALL journal, 3.25" stroke (arent the SMALL journals the best, and forged is great too?)
*** #3884520 , # gm26, #H1 6, # gm32, # G286 = 60cc chamber, 1.72" intake and 1.5" exhaust ( all the info I could find ).
Thanks, if I should upgrade, PLEASE offer advice ---
