3.8 - 4.3
Reason for downsizing is simple, economy. Health issues have forced me into a fixed income.( I'm not whining) with stock 350 2jet, 350 turbo and 2:76 gears it got about 18 mpg, hope to get it up to about 22 mpg.
My question was on the odd-fire even-fire timing and balance. 229 was 81 malibu engine and odd-fire engine, 4.3 is mid 90's and I ASSUME it is even-fire.(split rod journals), thus the different mag, pickup and question the balance of flex plate. If it is independently balanced no problem, but if flex plate is part of balanced assembly I dont want it bouncing up and down.
