Did Chevy make a big block 400?

No, they made a small block 400 and a big block 402. However, Chevrolet DID call the 402 a "400" in certain applications. They also called the 402 a 396 in 1970 (the 402 is a slightly over bored 396) because of they reputation the 396 had built in the SS396 Chevelle Super Sports.


What is the bore and stroke of Chevy 402?

The 402-cubic-inch V8 is nothing more than a 396-cubic-inch bored out by 0.030. the 396 had a bore of 4.094 in and stroke of 3.76 in. So the 402 had a bore of 4.124 in and stoke of 3.76 in.

How many 69 Chevy cst 10's had a factory 396 and bucket seats?

The last CST-10 that I looked at was factory badged as follows: CST-10 8 396, but I don't know how many were like it. The 396 was the largest engine option available in Chevy and GMC pickups from 1968 to 1970, the 402 wasn't introduced until 1971. So the previous answer claiming that all CST-10's had a 402 big block seems to be in error.

What size engines did a Chevrolet Chevelle have?

Straight 6: 200, 230, and 250. V8: 283, 307, 327, 350, 396, 402, 427, 454. Keep in mind that there were several different versions and performance levels of all of the V8's except for the 307 (only one 307 was offered.) The 427 was never a regular production engine for the Chevelle, but could be ordered with the Central Office Production Order program, and are extremely rare. In 1970 the 402 replaced the 396, but was still called a 396.

A 402 is really a 396, bored .030 over, already. .120, is about all there is before you hit water, so, another .090. You can sleeve the block, and go further, however, at that point you would be better to with an aftermarket block.


A wiring diagram for a 1974 Chevy 366 big block?

Your going to have trouble with that one. I remember 1974 like yesterday, but not a 366, big, or small block, from Chevy. If you are trying to say 396, again, trouble, as the 396 had morphed into the .030, version of the 402. There was a 348, but that died with the 409, in 63, I think, then there was the......
