Justhorsenaround - Thanks! I haven't seen any reviews or anything at all on the TSP unit. Did you use the included gear or reuse your old one?
I don't really care what it looks like under the hood, everything on the truck is going to end up having a major modification of some sort that will look out of place...function and cost are my most major concerns. I almost pulled the trigger on the Langdons HEI but Speedway has a rebranded TSP 6516 for over $100 lower price. I'm pinching pennies as best I can.
Looks like fixite's solution would probably be cheapest, gonna check into that as well. Looks like one could get a complete HEI distributor for a 250 from RockAuto for around 65 bucks.
Thanks all for the help!!
