    Fresh carnage!

    This engine was put together by an engine builder friend of my Dad’s (not a Mopar guy). He showed this to me this morning and it happened last night. He haven’t seen this mess in person. Any guess what happened?

    Late 340 exh. manifold research

    This manifold corresponds to a 340 number but has a date of 1/15/1974. Also, the exhaust ports in the center divided. I thought the center two ports on 340 manifolds were one hole like this one here … Is the 3614368-2 a 360 manifold? If it is a 340 manifold why does it have a casting...

    TTi step vs. 340 manifolds

    Stock 1973 340 with Z and O head. LD340 intake. Power steering Should I keep the manifolds or go through the hassle of fitting my TTi step headers around my torsion bars and p/s box.

    Carburetor size Question

It has a 360 intake on it and I've always been curious if the HD designation had it built with 360 heads and intake in 1976 or if these...

    Z head and O head on 1973 340

    I have a 1973 340 4 speed Duster that has a # matching engine and transmission. I would think with a car that still has a matching drivetrain the heads have a good chance of being what came on the car. The O head has 341891 B (5 is not cast) and the Z has 3418915. The O also has 360 cast into...
