    I swear it looks like the engine is sitting to far back, two other guys at the shop with 1st gens and both are BBC powered say that their valve covers and HEI distributor is nowhere as close to the firewall as mine.
    Can someone with a SBC give me a rough estimate on the distance between thiers?

    I put the x-member back just the way it came out but the PO had just replaced it, I'm sorta wondering if he put it in backwards. :confused:
    It was quite an ordeal to get everything lined up.
    Thanx

    Well all I can offer is what I remember. I had enough room from the front of my engine to the rad to install a BM150 electric fan and run a large Flex-A-light clutch fan so mine did sit way back. Without the fans I could stand between the engine and rad..
    Good Luck

    My spark plug wires touch the firewall. :doah:

    The engines in 67-72 4X4's sit further back than the 2wds. I have heard that the was done to make the front driveshaft as long as possible. :D

    The engine will be close enough to the firewall that an HEI distributor will barely fit - sometimes a little massaging actually has to be done to the firewall. So yep, the engine sits way back.

    The engine was placed so far back to allow the front driveshaft to be longer and possibly to give more clearance between the oil pan and the axle.
