4.3L vs 350 all else the same you get a small improvement.

Yes, the SBC, BBC and 6.2/6.5L share the same motor mount locations and transmission bolt pattern.

Not as much as you would think, ethere way you have to convert it to go diesel. You can get a fuel tank unit for a diesel or an older carbed truck.

You might need a transmission controler I think the gas engines ECU controls both the engine and the transmission.
Yes you may need an adaptor or different torque converter to go from an older non-L460E engine to a L460E transmission. Other wise the trans and bell housing will bolt right up.
It would be easier to put a TH700R4 in there, I am not sure of all the details when mateing an older engine to newer trans.
TH700R4 transmissions are cheap.
Drive shafts are the same between TH700 and L460E.

The 6.2/6.5 are so popular because you can run both of them N/A or turbocharged, they can be electronicly controlled or mechanical.

I think I have the best mix of 1982-2000 6.2 and 6.5 parts for a N/A engine.
I can give you a break down.
Right now the only part I would like to have different is a newer style mechanical injector pump. I can change that when ever.
I had one of the best 6.2L engines for fuel economy and will tell all.
