200 with 350 Holley

B

bernie_ramone

Hi lads, looking at ditching my Autolite 1100 for a 350 holley.
Anyone who has done this or have suggestions / pictures of their accelerator and kick down set up ?
Ive picked up a HEI dizzy too.
What sort of jet should i drop it too in Holley?

thanks :beer:
 
A 59 or 60 main jet, but the WOT orifices under the power valve could be leaned a couple of thou.
A professional carb. shop or i can do that mod & install screw in jets in the metering block under the power valve.
If you do a direct mount you will see a great difference.
 
Hi, I did the complete head swap with a two barrel adapter brazed on. See it on 1hotvega ebay site. Now the engine breathes, and the pedal is almost never on the floor like it used to be. 3 speed in a Bronco, so no kick down issue. I did use a lokar throttle cable. Get the Falcon Performance Handbook before you do anything. Good luck

The Holley 7448 350 CFM 2300 series was used in all kinds of displacement engines, mostly small V8's. Widely available( IE: inexpensive), all the parts and gaskets for standard Holley 4150 and similar aftermarket 4bbl's at Summit/Jegs etc.. . The (often cheaper $) 500 CFM version 4412 looks almost same but is not as simple for a responsive tune on mild 200's.


Important to check PV , often equipped with high- vacuum release PV's causing early over-enrichment with small displacement 200. Typical 4412/7448 main jetting @ Holley # 61 - 71 , see what the carb you get starts with, work from there ...

Accel can use modified pushrod or simple change-over to pull-pedal cable of Maverick/Grenada ...

'built' 170 in my '63 wagon:

350/4412's are favorite carb for modifying for my blow-though carburetor forced induction project . :

Some times the 7.5 or 8.5 power valve is necessary to fill a lean hole in the mixture during acceration.
Accelerator pump discharge can also cover this lean hole if necessary.
A wideband A/F tester is a must for exact calibration.
 
thanks lads, some good ideas and cool pics :)
My book is on route from USA.
Will drop dizzy in soon and test, before holley and adapters.
