350 or 327

[Gibson]

The 327 was the quick-revving, high rpm engine back in the day

Right,, but just like the 302 that was used in the HiPo Camaros, the short stroke engines depended upon high compression and hot cams in order to develop good power.
When you could easily buy pump gas of 100 octane, and without smog controls, those engines did ok,, but they are very dirty engines with high emissions.
The incoming tide of emission controls and lower compression is what killed-off those little engines.
Also, as vehicles got heavier, more low-end torque is needed and the small displacement engines of that day just don't have it.
Today, with aluminum blocks/heads, and forced induction with fuel injection you can get good power/torque from little engines,, but yesterdays tech couldn't do it.

327 n 350 are same block. Shorter stroke for the 327 obviously. I found a good block, all done ready for assembly. Just need to buy all forged internals now. If yah don’t wanna runs 327, prolly sell it n buy steel 350 crank.

A327 is a350 block with a 307 crank . Iirc. A 305 and 350 share the same crank stroke bore is different.

Same stroke and journal sizes but they are balanced differently and you wouldn't want to use a 305 crank in a 350.

The small journal 327 (1962-1967) was a performing machine. The internals were lighter and quicker revving. However with small modifications the 350 should have more low end torque but that is arguable. Back in the day many 327's would outrun the 350 with similar mods. I believe it was due to the limited head flow available with the factory heads of the day. Nowdays aftermarket heads can wake up a 350. In 1968 the 327 was built using the 350 block, therefore bigger journals. Good luck finding a small journal 327 nowdays. Different block, different crank. The 302 also went to big journals and used the 350 block with a shorter stroke than the 327.

I was under the impression the 302 was a 283 with a 327 crank but, that was a long time ago.

No you do not. Unless you get it rebalance.

Same stroke and journal sizes but they are balanced differently and you wouldn't want to use a 305 crank in a 350.

The forged small-journal 327 crank was heavy as hell. Rods were the same as every other small block. the pistons were also heavy as OEM forgings. I suppose the cast pistons were nothing special either.

I was under the impression the 302 was a 283 with a 327 crank but, that was a long time ago.

That's the 307, which replaced the 283 as a low-priced two-barrel V-8. The 302 was the opposite--283 stroke, 327 bore.

Since we're having this conversation, wasnt there a tiny 260 v8 out there also?

 

[Schurkey]

255, 256 = Ford
260 = Oldsmobile and Ford
262, 265, 267 = Chevrolet
265 also = Pontiac, but nobody remembers that one.
264 = Buick
266 = IHC

I thought it was something like that.

262, 265, 267 = Chevrolet

IIRC the tri-5 Chevys came with the 265 or at least the '55
