288 and 327 interchangeble Parts

Hello folks; I have a 1950 Super 8 with a 327 engine. I was looking for a better exhaust manifold, but what a found was a 288 1952 engine for sale. The engine is complete but frozen up. My questions are what other parts could be interchangeable between the two engines?. I do remember the 288 is shorter stroke, but what about the crank and cam?, and other parts.

Your advise is appreciated

Dave O.

The parts book would probably answer that for you and it is available either as a PDF in the Literature Archive or in database Forman in the Factory Parts List.

I am fairly certain that the cylinder heads are interchangeable however doing so would change the compression ratio

If you want something done right; you have to do it yourself

I own a 327 9 main one from a 54 Patrician, I agree the head is the same as you can see where the 288 was milled off the head casting and 327 stamped onto it.
I would bet a lot of other parts such as fuel pump, oil pump, flywheel/clutch, water pump, generator/starter, distributor, carb/air cleaner, bell housing etc. would swap. Likely exhaust/intake manifold. You have the benefit too of having the correct engine so you could check part to part to verify

Hi, thanks for the input. So far, according the the specifications book I have. Here is what I have found for reference. Compression 7 to 1 both, Cam bearings 5, both. Crank 5 mains both. Journal dia, 2.7465, both. Connecting rod journal dia, 2.250 both. Piston size 3 1/64 x 7/8" both. Distributor Autolite, and Delco same numbers both. Bore 3 1/2 both. Only stroke is different the 288 is 3 3/4 and the 327 is 4 1/4. So far, so good.

The heads are indeed physically interchangeable but without care such a change will also change the compression ratio.

Good News; I did find an intake and exhaust set up on a 1951 300 or 400 the person was will to part with for a very reasonable cost. Plus he is going to take them off for me at no extra cost. I thank you all for your advise, and information.

You are all a valuable resource for so many of us.
