Dropping a 440 in where a 383 was
 

Will headers from the 383 work fine? What about pullys brackets and such?
Just looking at what I might need. Thanks for the help.

mostly 440 and 338 can share most parts. some of the ones that dont, that i know about. distributor, distributor clamp, intake manafold. i think the A/C bracket is not the same, 383 to 440. all so an intake manifold that did NOT have a A/C bracket on it from the factory, may not fit an A/C bracket. generally the pulleys on a B-RB are different from A/C to NON-A/C. dont mix them. chrysler wanted more air through the radiator so they spin the fan faster, but the water was to fast. so they put 6 blade pump on the A/C unit, and a 8 blade on the NON-A/C unit with different pulley speeds for each. there may be other differences.

if i remember right the 383 had a 2 bbl engine, it had 9.02 cr the 4 bbl engine had 10.1 cr. my 1967 coronet book shows that both have the same cam. but i think its wrong. the 1967 440 comes only as a 4 bbl. 10.1 cr. with a little bigger cam that the 383/ ie 268. degree for the 440. my 1967 imperial book shows the 383-440 mild 256 degree. the 440 power pack 268 degree.

Nice 71 Cuda the headers will enter change, the motor mounts block the same just
remember intake and distribter wont brackets are hit and miss varing from year models.
