Chevrolet Performance
CT400 350ci Limited Late-Model
GM 604 Circle Track Engine
Upgraded pistons, rockers, valve springs and converted over to a solid roller lifter by Pro Motor Engines (PME)of Mooresville, NC. The valve covers changed for rocker clearance. Engine was raced for 30-40 hrs. between 2019-2020 and sent back to Promotor for rebuild, has not been run since. Other items w/engine: Lightweight 153 tooth flywheel, MSD HEI Distributor. Engine dyno at around 500hp, was approximately 400-415 on the chassis dyno.
Currently the engine has a stock volume oil pan.
The engine is internally balanced so it must use a Zero balance flywheel.
Distributor has the timing locked out and it’s a non-vacuum advance version.
The intake is a bit higher than stock, and is for a Holley type Carburetor.
The exhaust ports are different than the stock heads.
Engine was bought for a restomod project car but I'm going with an LS motor instead. Engine has been stored inside continually.
