Swapping 340 into 64 valiant. Center drag link hitting oil pan
Great info and experience showing up. Thanks
@mopowers for the comparison pic as that says it all. I can add that I've had very good luck with Kevko aftermarket oilpans. Not only do they have the clearance dimples but can be optioned with various effective internal baffling. I can see shimming the motor mounts up from the K-frame to get away with the S6 center link but I feel strongly about keeping a good intake system under a flat hood. There just isn't much room in any direction with an early A-body.
Just for fun here's a 65 Valiant with a 440 I once ran. You can do anything with fenderwell headers! And even this setup had a flat hood. Almost a sleeper.
