Working on a friends '62 dodge polara 500. He is thinking about having me put a 383 in it. The car was originally a 318 wide block car. Is it a direct swap like from an LA 318 to big block or does the K-member have to be modified. Can I use the wide block mounts. Not sure if he is going to go through with the swap or sell it as is. I think it is for sale either way. Would appreciate any good advice.
You need the big block adapters that bolt to the k-frame,schumacher now repos them.
will also need to change the trans as the bolt pattern is different.
It couldn't be a Polara 500 if it was a FACTORY poly head 318 in a 62. The standard engine was the 361HP in those. Are you sure of the engine? If it is indeed a 361, then the 383 would be a bolt-in. In the case of the poly 318, the steel motor mount brackets are different, the exhaust is different, and the transmission would need to be changed to a big block unit. There are also small differences in the radiator, and a few other bits and pieces. Dennis
Dennis, not sure of the motor for sure. But I do know it's a 500. So I guess it's probably a 361 car. The mounts that are welded to the K member are flat on top (horozontal) not angled like the later models. With studs on them. Is this car worth a lot since it's a 500? Even with the trunk rotted out?
Yeah, the 62's used that type of mount. The big blocks used the full sized car mounts, and the small blocks used the same K frame with an angled steel bracket bolted to the K frame, and the same brackets/insulators as the 63-65's did. I would use 318 car angled brackets, and 63-65 big block mounts/insulators. The car is DEFINITELY worth fixing up! I'd say if nothing else, make it look like a Max Wedge car (Beefy springs, Max Wedge exhaust, etc.). Dennis
