I just heard the 400 2 bolt mains were a stronger block. this isn't a all out strip car but a 16 yr old will be the owner operator. I didn't pay a lot and I got some nice pieces like the heads & M21 ect.
its complete and going in a father son 74 Camaro project. this is a 74 Camaro that will have this 400SBC & M21 4 speed tranny with frame connectors and a 10 bolt posi. I'm guessing the gears are 308s or 342s. kinda hard to tell as the clutch was almost completely out of the car, so it wasn't drove much with the 350 T10 in it. I put a new water pump on the 400 and just had the 4 core radiator gone through. going to run a 6 blade mechanical fan with the factory shroud. and it's an a/c car but most all the a/c stuff is gone, and there no money now for a/c so I think I will pull the a/c condenser till we have all new a/c stuff. then I will go back with a/c components big enough to run a R134a system. I have a complete serpentine belt system with a new R134a a/c compressor.
Light use then ok,for big motors though they warp and can pull out the mains
