I have the L31 in my 66 and it is not as cheap as you may think. If I had to do it over the LS swap would have been less money for a better motor. I bought the new L31 with tax it was $2200, the intake was $328, carb $420, distributor $330, flexplate $55, cam $280 then ad another couple of hundred for plugs wires coil ect and its now over $3800. Not to mention what I spent to have a 700R4 built. The 5.3 sitting on the floor for the 65 was a 31000 mile take out with the 4L60 for $1750 the mount kit was $70 and the wiring kit was $750 with the base tune in the computer. Thats about $2600 and includes the trans and it is EFI. The rest like headers and exhaust is a wash between the two so that for me is 2 grand less for engine and trans for the 65 verses the 66. I will be 60 on my next birthday and love my old school stuff but the gen1 stuff has for me past its time.
