Dealing with "big names" isn't always fun!!!!
Barton built the engine, had a few issues I fixed, we had the pan off and valve covers off and determined..... the engine had most likely NEVER ran. Hence the prep and cam break in. The "dyno sheet" we guessed fake years ago when I got it, the BSFC values somehow left off was a good indication lol.

Rance Baxter built the EFI, the throttle blades are positioned terribly, the linkage doesn't work correctly (one bank opens at a different rate than the other) the vacuum manifolds are done incorrectly (one is ported vacuum) and the injectors stillll aren't sized properly, but at least borderline. I'll fix it all when I take it off. The cylinders are imbalanced and the throttle blades stick at idle once warm.

And??? I have a John Cope tranny and PTC convertor. LOL I have my fingers crossed it works well!!!!!
