Re: 427 ci (good motor?)
quiet cat<br /> ya gotta go back to chebby school<br /> the 348 was originally a truck engine and later devoloped into the 409, last produced about 63 or so. the 348,409 were unique and readily identified by the w shaped valve covers, the combustion chamber was part of the cylinder and the head was flat with no combustion chamber. in its heyday the 409 was avalible with twin rochester 4bbl and a flywheel rated Hp of 425. I dont recall any production runs with the mechanical FI used on the 283,327's of that era. the 396 was released in 65 and updated in 67. the cams on the 65,66 models were different than the later big blocks had later cams have to be modified to use in early blocks. the later 396,402,427,454 all shared the same block configuration and each could be bumped up or down as needed. the 427 went out of production about 69 or so but was a fine motor. <br /> it more than pushs the limits of an alpha drive, by the time you get it propped correctly you will most likly grenade the upper case.
