I've heard a majority of the 70's vettes' chassis can hold a small block or a big block without having to cut an' weld anything. Does anyone know if a 69 will do the same. Basically I wanna take the 350 out of mine and put 427 in, since it's not the original anyway I might as well have more....right?
I took the small block out of my 72 and installed a 454, it fits fine but might be a little longer than the small block. The problem I ran into was finding the pulley/ accessory mounting pieces and I ended up going with a street and performance serpentine drive system. If I were doing it again I would look into the vintage air serpentine drive setup, they have it out for big blocks now. You will need a new exhaust system for it so thats the perfect excuse to do the hooker header/ sidepipe thing. I also used an L-88 aftermarket hood to have enough clearance for a decent air filter setup.

The frame from 65 -82 will accept a bigblock (63 and 64 do not have the necessary notches in the front cross member that allows for clearance for the BB pullies). Just remember the suspension changes, the increased cooling, the accessory brackets, and the low-rise intake that you will need.
'77 L-82, black on black. Full mod 406 small block
you will need all new acc brackets, fan shroud, exhaust, suspension, etc. have you considdered a high-hp small block instead?? it may be cheaper in the long run. Brian
