351 Cleveland 4V CJ Rebuild

Hey People!!

Maybe you, VWHobo, can help ?

This Wednesday (two days from now) I am getting my 351CJ rebuilt.

I went to many shops in town, and the one I've chosen was very professional, clean, and knew what they're talking about. Except one gripe:

I am confused as my shop suggests getting a 750cfm carb for the cam and manifold combo I am using. I will be changing to 3.55 gears soon, and my wheels are 15" with a 255/60 tire. IMHO I think 750 is too huge!! But my cam is huge and I have the exhaust to run such a high cam (true dual 2.5" w/H pipe)

Here is the specs of my cam... As you can see, its a dual grind camshaft by the different lift specs.

COMP CAM DUAL ENERGY 275DEH
RPM Range: 2000-6000
Advertised Intake: 275
Advertised Exhaust: 285
@ .050" Intake: 219
@ .050" Exhaust: 232
Valve Lift Intake: .515
Valve Lift Exhaust: .541
* works with mild converter

My manifold specs:
EDELBROCK PERFORMER 4V (Idle -5500rpm)

My carb shop wants me to get:
750cfm 4bbl Edelbrock Performer
square flange, electric choke

QUESTIONS
1) Would I have to change my torque converter to a stall of 2000rpm?
2) Is 750cfm too big?
3) Will the combos listed above work?
4) How much gross hp can I expect?

Thanks in advance people!!!!

Testy,Testy.Remember,there are few folks left that know what an OHV Ford is Let alone setup on an performance overhaul.

First off,a 351C 4V is not big on torque,and you are adding a pretty big cam.Think loose convertor,possibly in the 3000 RPM range.Thats alot of cam for a land yacht.Expect the need for a vacuum can if stoping is high in your list.

351C's are known as a decent revver,so a 750 sounds close.I might try something a little bigger.

Power?Tuned right,expect 375-400 ponies.

I would be glad to help - unfortunately, I am not familiar enough with the 351-Cleveland or Modified Cleveland to give any suggestions or much advice.

How did it turn out?

72Torino,
How did your rebuild turn out? I am thinking of using the same cam on my 251C-4V (10.6:1) with an Offenhauser Intake (5964: Intake Manifold, 360 Degree, Split Single Plane, Square Bore, 351C 4V) and a 750 cfm Holley carb. Was the cam too big? What did you end up with and how does it perform?
Thanks,
Ian
