You don't have to change the cam, but a cam that is perfect for a 350 may not be perfect for a 383. Cam manufacturers offer technical assistance to help you select the right cam for your application.

What size crank do you use in a Chevy 383?

There are new cranks from the aftermarket for this. Check with Summit, Jeg's, or similar. You can also use a crank from a 400, but the main journals will need to be modified to fit the block. The stroke is 3.75".


When was the 383 4 bolt main engine made?

Chevrolet never built a 383 for production use. Many aftermarket suppliers have produced a 383 Chevy. It was originally built by taking a 400 crankshaft and having the main journals reground to fit a 350 block. The combination of the 400 crank and rods with the 350 block and pistons yields a reciprocating assembly with correct compression height. In standard bore, this would make 377 cubic inches. The 383 would be a .030" overbore. Since most of those parts have been used up, the aftermarket now produces all new parts to build a 383. It could be noted that Chrysler produced a 383 for many years during the 60's and 70's. It has nothing in common with the Chevrolet.

Will I have to change the heads on your 350 engine to change the cam shaft from a 260 to a 282?

NO. There is no reason to remove the heads are to do any valve spring changing on that size of cam. You may find it helpful to get a different torque convertor to compliment the new cam. Convertor manufacturers can be very helpful in suggesting the right combination for your application.


A pre 1988 small block Chevy 350 has no retainer on the camshaft why and what keeps it from moving?

The pre-88 engines have hydraulic lifters. The bottom of the lifter is slightly dished and the cam lobe is slightly domed; hard to see just looking at it. Anyway, as the cam rotates, the lifters actually spin and hold the camshaft in place. That's why you have to use new lifters when using a new cam, so that they wear together. If you don't then the new cam will eventually walk its way against the timing cover.
