I6 2 Bbl and headers ?'s

240 I6, I am researching about putting a 2 bbl on my stock intake and maybe some hedman headers. now I know that I will lose the heated manifold, but I have a carb plate that has a heater hose attachment for the water to flow through that I think will do the trick of keeping the carb warm. what I was wondering is if anybody has done this to theres and if it really made that much difference. and which would do more for power, carb or exhaust or is it a sweet mix of both? also has anybody used the 2-1 adapter instead of an after market offy or cliffrd. ok well let me know any tips. and I will post mine after I have tried it. thanks
eventually I am gonna rebuild it with a 300 lower end.

I'm using a 2-1 adapter on my '81 F350. I have a Motocraft 2V on it. The main prob I had was getting the throttle cable hooked up. The stocker was about 4" too short. I used some "Southern Engineering" to get mine to work, but a universal throttle cable is your best bet.

could you tell any difference on performance? what kind of exhaust do you have. and ya I figured I would have to engineer the throttle cable a bit

.thanks for the reply

The 1V I replaced was in pretty bad shape, so the performance diff was pretty big. But I don't really know how much it was. Throttle response definately improved, IMO. The bottom line is the carb will still be bottlenecked by the stock opening. An aftermarket intake will set you way ahead of the game (except in the $$ department!).

Exhaust on mine is still the stock single outlet (with plenty of cracks). I plan on swapping to EFI exh manifolds soon & run true dual pipes & Smithy mufflers.

I put headman headers on a rebuilt 240 about 15 years ago didnt get to the carb change with the power output change didnt need to. I was at work one friday (pay-day) started talking about puting headers on my old 74 F-100 so when i got home i started calling parts stores they told me 235.00 so i just forgot it and the next day went to the flea market the first row there was a man selling brand new parts where a parts store had closed and there they sat brand new in the box and when the man told me they were 35.00 i just about fell over . knowing i had to have the truck to drive to work on monday i did what any one would i started as soon as i got home they went on so easy in 1 hour i was driving open headers to the parts store for mufflers i chose 2 big block header muffs . Drove it all winter with no probs. when its cold it sounds like there is a big cam in it just baby it a liltte till it gets warm it will out run v8s

the problem with headers is that when it gets to hot that the starter gets hot also and its hard to start after

Ive heard alot of people say that, and I do believe it but never had it happen to me. I have put headers on many cars and never had that problem, but me and my father rbuilt 2 cars basiclly the same model and engines I however put headerson and he went stock exhaust. and his heats up and doesnt want to start once warm and mine starts all the time everytime. hopefully my luck carries on to this engine, Id hat to have to eat my words so knock on wood. thanks for the reply
