Should, may have to trim the pan a bit to get the best fit. I have been working off and on with a '65 from the 90s with all its goofs, and the chassis I'm going with is from the AMT '66 Olds 442, as they were once plentiful and cheap. Lots of interchangeability prospects, consider '66 Olds, Lindberg 67 Olds, AMT and Revell 65 and 67 Chevelles (both stock and pro street available), Lindberg (now AMT) 66 Chevelle, aforementioned 66 GTO, and so on. Chevy pans will need to swap out trans cross member for the correct B-O-P style.
