240 putting a new intake on it

[knuklz88]

i got a 1968 f100 240 cid putting a offy intake with an adapter to put a holley 2 bbl on it
also putting a set of headman headers. didnt know if anyone had done this before and knew if there was any major that i should do. like do i need a more powerful pump than the stock block mounted one.

The offy is it a dual port or is it a single port? Need to know. Headers no problem though the carb will take longer to warm up as the original design has the intake bolted to the exhaust under the carb just for that purpose. The stock fuel pump will be okay.

dual port on the offy any reccomendations on the carb? i was looking at a holley 2300 man choke

You need a small 4V to make the manifold work right. They require the secondaries to run in the larger ports. That is the one and only reason that manifold is still made.

Don't pay attention to Holley's prices.

thanks for the advice yall also wheres the best place to wire the choke up at? talked to the guys at the shop i work at they say the generator is the best place

[austin]

i dont rightly know ive never dealed with wiring in a electic choke mines manual

also with the efi manifold you have to grind one tab down a little bit not very much though

[Dragon]

Did you buy those headers new? I used Hedman's on a 240 without that problem. My Electric choke is tied to the ignition switch before the resistor wire.

[austin]

i bought mine brand new a year ago and i wish i would have just bought some junkyard efi manis

[Dragon]

The Hedman's I used were away from the engine there is no need for them to be close to the engine in a truck. Now in a Galaxy or LTD used as a taxi that is a different story. Complain to Hedman and see what they say.

if i were to go the efi manifold route know anyplace sells them new or am i headed to the scrapyard

[Dragon]

Scrap yard. Ford only kept the parts on the shelf for 7 years after the last one was made. I am not talking the local shelf either. Though you might find one dealer that can find the old hidden stock. That is mainly were NOS parts come from.
