Cool Re: What size Holley?

If you call the free tech line for Holley or Edelbrock, they will ask you
questions about your cam, port size, heads, etc and then give you the correct CFM.

Being a Christian Doctor, who likes golf and lives in Oklahoma.....
I'm guessing they'll suggest a 650cfm with bigger jets.
Give them a call, let us know what they said..

Re: What size Holley?

Some had Holley 3310's 750cfm
Tell us more about the motor. Is it stock, mild cam, aftermarket intake, headers... how do you drive the car? ie.. just around town, long trips, drag strip, daily driver, weekends only... automatic or manual trans?

Re: What size Holley?

Best I can tell its a stock 396 with headers. My current holley is a 3310-4 which I guess is a 750.

Re: What size Holley?

If it's stock or lightly modified, get a 750. Anything more is just wishful thinking...

Good luck.
Jim

Go here; http://www.holley.com/ in the upper right corner of the screen it says "enter your CID". It takes you through a nice calculator and asks lots of questions.
Check it out.

Re: What size Holley?

Car won't idle well at all. I've had the car rebuilt the by the best but it just doesn't run right. I wonder if the avaenger seried 8870 would be too big?

Re: What size Holley?

Here is a link to Holley's PDF on Carb selection:
http://www.holley.com/data/TechServi...Carburetor.pdf

Quick Reference guide:

Also here is a direct link to Holley's tool what David mentioned:
http://www.holley.com/applications/C...bSelection.asp


Assuming Street under 6k RPM Holley seems to recommend a 600cfm carb, but that is just their simple tool hard to tell with so little info.
