Has anyone done this swap and kept the original 700r4 in the stock location? Thought about a 4l60e, then you need a trans controller. WHat would need to be done for kick down? And converter lockup? (probably just an on/off switch). Truck is a 86 k5 with a 700r4/np208.

I wonder if a particular brand of mount would work better, i will more than likely stay with the stock manfiolds and intake, i may put a cam in it to give her a little more power. The AC lines will have to be modified i assume, thats no biggie, and the alternator wiring.

For a gas tank, would an efi tank from a 87-91 work (with a different pump of course)?

And for the computer, i will more than likely stay with a stock computer, just modify it for a corvette regulator setup (one line instead of two). Any or tips or builds you guys have done? Things to look out for?

And final question, are the 5.3/6.0 sizes externally very different? If i find a 6.0 or 6.2 with low miles for a reasonable price i may go that route instead.
