are there any mods besides ECM and wiring required to install an LT1 and auto trans from 94 z28 into a 92 RS 305 TBI 5spd?

Use the search feature. I found posts from Texas LT1 (I think) that had info on the A/C clearance (not the frame on a 3rd gen)

Friend just got done with a 95 LT1 / 4L60-E into a g-body. Includes working SES light & VATS. The wiring seems a lot less than I originally thought (plan the same sway myself)

I don't know how you'll be able to use the pulse from the transmission with your speedo; the pulses are different to the best of my knowledge.

The trans. should have the same tailhousing as any third gen 700-R4 so that'll work, as will the driveshaft. I would keep the stock alum. 92 radiator, and run the heater line from the H2O pump from the pump to the old heater-core - to - PS tank of the rad - port.

The small coolant line that goes to the DS rad. tank in a 4th gen F can be capped off; the Vette does not use it.

The upper and lower radiator hoses are guesswork; try an upper from a 4bbl 3rd gen trimmed; the lower, you *might* be able to use a 307 g-body upper for that.

As you can see, I take notes when my friend does this ch¡t ; Plan on the same swap myself, but with T56 into 86 Monte, which is already hydraulic T5'd....

The wiring is the most difficult part...by far! Take a look at the site in my sig, for a brief overview of what I did to get my swap accomplished.

It's not the only to do it, but it's instead how I did it. Good luck and have fun!
