Do 327 and 350 block the same?

Do 327 and 350 block the same?

The larger sized main journal diameters of the 1968 327 small-block, 2.450, are the exact size of the later 350 small-block. The difference between the two is the length of stroke on the crank, 3.250 for the 327 and 3.484 for the 350.

How much horsepower can you get out of a 307?

Combine these parts with a good 600 to 750 cfm Holley carburetor, an HEI distributor, and a set of long-tube headers and your 307 should make around 325 to 350 horsepower, perhaps even a bit more.

How much HP does a Chevy 307 have?

Power. When it was introduced in 1968 the 307 was rated at 200 horsepower at 4,600 rpm and 300 foot pounds of torque at 2,400. However, the federal government’s emissions regulations of 1972 saw the 307 de-rated to 115 horsepower.

What kind of crankshaft does a Ford 307 have?

My engine book shows the 307 was essentially a 283 with a 327 crankshaft. Maybe the crank is actually a 327 or the engine is actually a 350. If you can post some block casting numbers and cylinder head casting numbers I’ll be happy to decode this and see what’s going on.

What’s the difference between a 350 and a 327?

327’s are more expensive to build than the 350. 327s rev higher than a 350. I like 327s becuase not everybody has them, but I opted for a 350 stroked to a 383 because its cheaper….or was it.

Can You interchange parts between 327 and 350 Chevy?

The beauty (or bane) of the small block Chevy was that you could interchange so many parts between the 307, 327, and 350 that you may have parts from all three of these engines together in yours. If you’re building a show car that needs matching numbers and documentation, you’ve got some work to do.

How do I know if I have a 307 or 350?

Suffix codes show “D” type codes for the 307 and “H” type codes for the 350. A tape measure will not be effective when measuring bore sizes unless it’s astronomically different and seeing as how the bore is around 4 inches and there’s 4 bolt mains you likely have a heavy duty 350 and that ain’t bad. The only engine more desireable would be the 302.
