Manifolds to suit 250 2V

Hi,how is everyone?

Question: what inlet manifolds are available to suit the 250 2v?

(I use the term available lightely... eg what manifolds were ever produced aftermarket)

So far I own a standard manifold and a rare triple 45mm webber manifold and I have seen a SU manifold on ebay (was "buy it now" before I could bid :( grumble...)

What I really really want is a 4 barrel manifold (I like webbers, but nothing is as sweet as a big fat holley) and have been told by an older ford guy that once in the past Cain made a 4 barrel manifold to suit..

Has anyone seen any other manifolds to suit the 250 2V other then the ones Ive listed?

Better still anyone got a 4 barrel manifold for sale??

Please be sure to note this isnt the cast iron cross flow head, which often people get confused with when it comes to manifolds...

On a similar topic, has anyone fabricated an EFI manifold to suit? If so do you have any pics?

Cheers

Re: Manifolds to suit 250 2V

The most total cfm flow I have got thru a 250cu motor is 480cfm, so a 4 barrel carb over that cfm flow isn't very practical, unless its sitting on a blower.

Are you planning on show or go.

Re: Manifolds to suit 250 2V

Hi,

A 450CFM 4 barrel would be about the size of the carb I'd want to run.

If as you state the most one could get from a 250 is 480cfm then that would mean the 450 would be undercarbed on a 250 motor.

I agree that massive carbies on a small engine is stupid, but the reason I wanted 4 barrels, is that I can make the primaries quite small, and the secondaries bigger, which is how they are supposed to work right?...

Re: Manifolds to suit 250 2V

Hi bad_mk1_escort.

Unfortunately, my 250 2V is an entirely different beast in comparison to the XF/ZL series of I6.

The 250 2V isnt cross flow and unfortunately has different bolt patterns on the inlet to that of the XF/ZL.

I am actually considering (once I've driven the car a bit) getting an XF system and modifying it to suit my 250 2V, but I was interested to see if anyone had built their own EFI system based on a plenum and runner system, as this seems the easiest method to me..

But back to my first question:
What manifolds have you guys seen in the past to suit the 250 2V??

DO WHAT I DID. MACHINE AND GRIND THE STANDARD MANIFOLD AND WELD ON A ALLOY 4 BL 1" SPACER PLATE. THIS WORKED VERY WELL AND TOOK A 600cfm HOLLEY WITH YELLA TERRA VALVES AND A MILD PORT.

Re: Manifolds to suit 250 2V

Hey xrglen,

Thanks for that info, im wondering whether this is what everyone does and whether the cain inlet never actually existed and the guy I spoke to was confused...(He's a V8 guy not a 6 guy also..)

I was considering doing something similar for my 350 2 barrel, but the aluminium head welder that I was speaking too was not overly confident that he could weld the aluminium.
to quote him:
"Im not to keen on making a paper weight out of such a rare part as the aluminium could be crap"

So in your opinion there are no issues with welding the factory manifold?

So far I've just got a 2 barrel adapter CNC'd to take the factory holes....

Kinda wishing I didnt pay $400 for that 2 barrel holley now... hahaha..

IV DONE THIS TWICE TO 2V MANIFOLDS AND ONE LOOKED 50 YEARS OLD BEFORE I STARTED. ALL WITH NO PROBLEMS. TRY A DIFFERENT FABRICATOR.
