Since I was able to get the .010 ground Turbo crank, I will definitely be using it instead of the NA one. I pick up the eBay engine tomorrow, and my buddy in Midland is giving me another NA '79-'80 3.8 he has, complete block to heads
No way I will use '78 heads. Tall-port '79-'80 heads from a NA motor.
Correct on the KS hole on the back of the block. I will either have it machined into the block in the picture, or use the block from the other engine.
I believe the manifolds are from an '80 engine. Casting numbers are L: 25507801 and R: 25507802
Basically, I got a rebuilt turbo, manifold, plenum, exhaust manifolds, up-pipe, down-pipe, crossover pipe, exhaust- to-cat bent for a Vega, an MSD-6 BTM, and various pieces in a generous swap from a friend. Found an NOS '80 ESC box on eBay; need a KS and wiring. The guy who won teh Turbo Riviera carb #17080242 I was bidding on can't use it and now wants to sell it to me for his cost.
Still have questions on how some of the little stuff will fit together, but I'm trying to nail down the big stuff now.
Thanks again,
Dave
