I cant add anything here for tech help but I will say the 402's aren't a bad motor. I had one in my 79 k10 and it had enough power for normal truck uses and still ran 14.7 in quarter @ 92mph if memory is correct. The small oval port heads and low compression they usually have means they run on even low octane fuel and are decent on MPG for a big block.

Going with the muncie is a good choice with that motor also, the TH400's are great transmissions for reliability even in rough service vehicles or big power but they really suck HP to spin.
