Engine Trans Swap
Hi,
I just picked up a 69 vette convertible and am looking to resto it with a 427 crate motor/ Trans. Its got a 350 and 4sp trans.
Any resources you guys can point me to for figuring out what and where to buy?
Appreciate anything!

Welcome to the forum!
There’s big blocks, small blocks, or even a newer small block…
GM LS COMPATIBLE 427 C.I. PRO SERIES ENGINE
If you want to replace the transmission I would definitely look into a 5 speed conversion. Silver Sport transmissions has a complete TKX swap kit for C3s.
TREMEC TKX 5-SPEED KIT FOR 1968-1979 CORVETTE

Or step up to a 454, new from GM.

100% on the TKX (or a 6-speed Tremec Magnum).
