Greetings! And thanks alot. I thought your answer to the carb question was how it worked, but I wanted to be sure before I drop 300-400 bucks on a carb.

Another question on big/small block. Does engine size have anything to do with it? Meaning is there such a thing as a big block 350?

No. 350's are in the small block family. You can bore and stroke them to a much bigger size, but they are still referred to as a small block. It is designated that way because of external physical size, not internal cubic inches.

Ah! Thank you!


That answers a very old question for me.

Some of the guys like Denny on here are very good at finding drawings and things like that. Maybe one of them will post some showing the difference between a small and big block for you and others who may need this info.

That would be great!

Also if my edelbrock manifold has 8 bolt holes, that mean it will fit either kind of bore, correct?

Well, no. 8 bolt hole intakes were Vortec style, used from I think '87 up, and only on small blocks. Earlier (1955 up) used 12 hold down bolts on the intake.

If yours is truly a '74 engine, it should have 12 bolts. Looks like someone has put in a later engine.

PS: Shoot us a picture or two of your engine.

Wait, 8 bolts on the Carb flange or intake to heads?

8 bolts on the Carb flange means it will probably fit a Holley or Edelbrock carb.

The intake to heads should have 6 bolts each side I think.
