We have a 1969 F600 with a 330 FT with a four barrel intake. It needs a new carb and I was just wondering what size and brand would work the best. Any ideas??? Also, we would like to switch the points out to an electronic ignition. What would be the easiest way to do this?

 

Sounds like a real good idea to me. :)

Question:
Does the distributor and drive etc swap from FE to FT?

Some swear-by them and other swear-at them but my Ford Dura Spark has worked perfectly since Feb-'75. Well ok danggit... the module went out in about '79 ;) but I believe that was my fault! Replaced it with a Blue Streak (Standard Motor Products) and it's still in there.

The original module had too much voltage applied to it since i was messing around with a weak battery. The original module never actually quit working -all the way- so it never left me stranded anywhere, it was just acting up and would sometimes let the engine die etc.

Regarding the carb, I'd be looking for a 465 cfm Holley 1849 or 1848, or an Autolite 1.08 carb. The Autolite might be hard to find.

 

Well I would be looking at a new edlebrock or holley 600 cfm carb.The edlebrock 600 cfm carb on my 75 F-600 truck is a dream compared to the crap holley that was on it. gas mileage went up after the swap too. I can get a steady 5-7 MPG out of it.

 

Ok, thanks. Would there be any downfall to going with the 570CFM Street Avenger from Holley? I've heard some people say that a smaller carb like the 465CFM is better for more low end power. Is this true? Also, i just found out that DSC motorsports sells a bushing that allows the use of an FE dizzy in an FT block. So with that in mind, we will probably put an MSD ignition and distributor in it.

 

stock FE dizzy and Pertonix or Crane-Xri with a spicy coil maybe ?

 

No the small carb will not help with low end power. The 570 from holley is a bad carb.In order to put a msd dizzy in it you will need the bushing from DSC ,new FE oil pump and a oil pump drive rod. The FE dizzy will not accept the larger 5/16'' drive shaft so the pump and shaft need to be swapped.

 

If it was me I would find a stock FE Dizzy and if it is the points type convert it to the pertronix set-up. Really no need for a MSD and it will save you some $$$.

Otherwise whats wrong with the one thats in there??? Better yet leave the Dizzy in it and get a pertronix set-up so you wont have to pull a pan and all sorts of other crap! JMHO

 

The points conversion kits don't fit into a FT dizzy as they have the tach drive gear mounted inside.

 

If it's a true 330 MD it will use the same dizzy as a car engine. If it's a large crank 330HD it will use the FT style big bottom distributor. As far as pertonics if it takes the std Ford points set your good to go . Not all 330's had a govenor or a tach drive distributor, many of the medium duty engines had a distributor like a FE. If it has a tach drive or govenor distributor it has the big oil pump drive, if it has the plain looking dizzy it's probably the small drive oil pump. Butt as we all know if its Ford anything can be found. The info above is from 25 yrs in the salvage business and is subject to Murphy's Law. Also there are the 330's that were used in the U Haul trucks mostly these were small crank small bottom distributors --Butt there were exceptions so don't take anything for granted.

So guys, would the plain old school Holley 600CFM be a good match for this motor? Also does anyone know what size the factory 4 barrel Holleys on these engines were?

 

The factory carbs were 585-to-600 cfm and either a velocity or distributor controlled govenor , later ones had a electronicaly controlled govenor. As far as a replacement most anything in the 600cfm range will work OK. The Edelbrock 600 gives good performance and suprisingly good fuel milage, the Holley performs well but the does not give the fuel mileage of the Edelbrock. Either makes a good replacement. If you luck into a Ford 4100 that works OK as well.

OK, thanks HOTWRENCH. I think I'll probably just go with the 600 Holley since many came with this carb and since mileage is not a concern with this truck. I'll compare the dizzy with my FE one in the shop to see if there is any difference.

 

Most of the FT motors were governed (either carb or dist.) to about 4000 rpm max as that was all the cam was good to. A vacuum secondary carb will work but you want as small a primary venturi size as possible to help the bottom end these motors produce. Revving the motor past 4000 will just beat it up for no increase in performance.

 

Isn't that the Gov????
