I have questions about the bolt holes to use on the 455 going into a 64 and the stock location of the ones on a 67GS400. I will be putting my 455 into the 64 skylark soon and need to know what holes on the engine guys that have done this swao used. Did you use 1&3 or 2&4? Also what is the stock location on a 1967 GS400? Thanks for the help, I just want to do it correct the first time.
Ed, Holes 2&4 definitely. I checked my 67 GS400 last night and that is where they are. Mark PS, I did the 455 swap into a 64 years ago too. If you need any info, If can help.
