Thread: 383 small block cam kit?

Tweet

Does any body other than Gm performance make a cam kit with cam roller lifters and springs.

Sure!!!! All the cam companies have numerous choices.....

I got an offer a 500 cfm edelbrock carb factory rebuilt for this motor for 80 bucks. it should be ok for street don't you think. They recommend 670 what do you think?

500 would be a bit small for a 383.... I'll be running a 750 on the one I'm accumulating parts for.... 670 would probably be an excellent choice on a mild type stroker though!

Here is a tip. To give you a ballpark number for the right sized carburetor, simply double your cubic inches, and that number should be reasonably close for an average performance build. 383 X 2 = 766 so a 750 would put you in the ball park. One step smaller for a mild build and one step larger for an more radical build. There are always other elements that play into choice, but this method works well for getting you close. An old mechanic told me that when I was a teenage gear head, and I have always remembered it.

^^^ yup that's the rule of thumb I use to get close CIDx2

If you want to get more scientific:

CFM = CID x MaxRPM/3456 x VE

Where VE is volumetric efficiency. We use VE=80% for street motors 110% for race motors
