Will 350 CK 1500 headers fit 305 CK 1500?

Answer 1

Yes the head design and exhaust manifold bolt patterns are the same on most gm small block applications. There is a misconception on block sizes, reality is the following engines are small blocks and most parts are interchangable. 289 305 307 350 383 400. You can really tell these engines apart without checking casting numbers. dont just check the head casting either like i said parts can be swapped. Check the rear of the block by the oil sending unit (by distributor)

305's are 350's with smaller cylinder bores, less cam, low flow heads etc. emission motors, but they can easily be built to three hundred horses.

If you can put a 305 in a camaro you can put a 383 or 400 in it without a problem the blocks are the same sizes but the strokes and bore are different.

It makes you sound like an idiot when you ask if a three eighty three will fit in the place of your 305.

This is where the stroker comes in a stroker is a three fifty with a four hundred crank.

(You cant stroke a 305 with a 350 crank because the strokes are the same)

It wont fit naturally, so the block must be worked.

The point im getting at is that most small block parts interchange especally exhaust manifolds.
