The only reason I ever thought of doing a late model GTO was a visit to my favorite chassis shop and he was parting one out. He used the eng/trans for a customer car and wanted the rear end for one of his projects. He told me it would be about 20k to convert to SS with 8.50 cage, 4 link, rear end, and fuel cell. I didn't go ahead on the project because I thought I should finish off another project instead. He still has the car but it needs more parts now. Needs front fascia, grille, one fender, rear fascia and rh quarter panel repair if anyone is interested.
Remember that when building a Pontiac motor, it will cost you the same regardless of engine size. My thought is that a mid seventies 455 would be a good choice when compared to similar year 400 motors. Yes I know the 428 with the Edelbrock heads has an even better hp rating but when did you last see a set of those heads for sale?
