I found a 327 +.060 for $40 and a free 30k mile 350. Which one would be best for the 56?

Travis i wouldn`t be afraid to run either one of them. I pulled a 327 out of my 57 and the only reason it`s not going back in is because i decided i wanted to run a fuel injected engine. The 327 had all kinds of power.

If the bores on the 350 are good and original, that's the one I would go with. With the 327 being +.060", it's on its last legs, not reboreable any more.

I'd put the money into a 350 first, but the 327 engines also have great potential.

IS it a large journal 327? If it is all of the internalls will fit in the 350 and be a 327 That is what I would do I like the sound of the short stroke 283 327 unmistakable sound

I agree, you could destroke the 350 to 327 and that would be cool. But, if the 350 is good that would be my choice. I think some people just think that saying they have a 327 sounds more retro or vintage or cool: go with the cubes. I am personally satified with both. mike

For free and $40, I would get both and make up my mind later. Use the other for trade stock or sell for something else. Can't go wrong for that kind of money.

That there is sound advice. The 327 will be worth some cash to someone out there. With it being already bored .060 over that is to much for me. With core shift on the old blocks you really don't know what you have and you could have overheating issues. The 350 is a no brainer as the only differences that could have an effect on you is that the 350 doesn't have the rear draft tube so you'd have to run vented valve covers. However the 350 can have four bolt mains. Other than the small journal mains on the 327 those three things are the difference.

The rest of the parts are pretty much interchangable. Some like the 327 over the 350 but to be honest... I stroked by 327 to 350 and no one is the wiser...

Personally I prefer the 327 only due to nostalgia. The 350 makes more sense, but I would destroke the 350 to 327 just to make it is converstion piece.

If all you want is to say you have a 327 just tell everyone it's a 327 and build the 350 . Me personally I have had 2 327's and they didn't hold up for me.( I was in high school maybe that explains it).I could put 200,000 miles on them now. 327 revs quicker but I perfer a good old 350

You are correct. I left it out as it seems I can never find one of the large journaled blocks when I need one. Do you know if ALL the later 327's were large journal or was it specific to a certain castings??

I know some of them were 302,327,350 blocks same number but Im not sure of casting numbers I have a few books but dont anyways belive them machine shops have also told me they are wrong alot I even have a a set of 202 heads that the casting number says they are 194 machine shops toldme most heads brought in that say they a re 202 are 194 stock 202 are very rare just an example but if you want large journal just use a 350 block with a 327 crank but I would think a smaller journal is less friction and weight so faster reving but I would use a forged crank

350 v/s 327

I'm running a 1969 large-journal 327, which uses the same bearings as a 350. The cost of 350 bearings at the time I rebuilt the 327 were about half that of small-journal 327 bearings. I was told by a machinist who builds high-performance engines that you can install a 400 crank in a large-journal 327 (makes sense) with some block modifications if you ever wanted a stroker. I just like 327s; I wax nostalgic as I replaced the 283/3 speed with a 327/T10 in my first '57 Bel Air Sport Coupe in 1970. Mark
