One other note, I don't see a Clifford four barrel intake.
With transmission and complete oil pan to carb I would say nearing $350.00 if you find someone needing what you have.
I just did this to my 66 Plymouth, what is the engine in right now, or did U miss it in the add ?
I have $600.00 in my heavy stack small block transmission, paid mor then that on my headers, I have 300 in my rearend, not to mention all the money spent on engine mounts, shifting linkage, radiator, distributor, carb, intake, kick down, drive shaft and thats just part of the list.
If you have an early A body 66 and back the tunnel will have to be worked to put a 727 auto in , if you count your labor and time with out the car on the road its a big undertaking. Good luck sir.
What kind of car ?
