Hi guys, Im new to the forum. I just purchased a 63 vette roadster. I think it was built July 63. Does any one know what the correct number on the front pad would be for a fuelie? Also it the block is a June 63 and the heads are 461X but April 63 does that sound right for original engine.

If I remember right, a "double hump" casting on the ends of the heads would designate the 2.02 valve, fuelie heads.

 

3782870 all blocks, fuel injection is 7017375 according to Corvette Black Book
