1975 F100 w Ford Racing Crate 302 - Runs awful!
 

I posted this in another guy's thread but i don't want to risk hijacking his thread so i started a new thread.

I just bought a 1975 F100 truck. It is described in my signature.

The truck idles really rough and has zero power.

I took it to a local shop to have it checked out.

I also called technical assistance at Ford Racing to ask about it.

The tech said the rough idle could be caused by vacuum leak. If that is the case, I am sure the shop will find the leak.

As to the total lack of power, he says it could need a higher stall converter or a milder cam which could give better torque lower in the RPM range. That's way over my head.

I guess i just don't understand why the truck wouldn't already be set up properly when practically the entire engine was designed and installed by LoneStar Performance (one of Ford Racing's dealers).

I assumed they would know what stock parts were on the truck when it was brought in (converter, cam, gear, etc.) and the engine they install would be compatible to provide the most performance.

I plan to use this truck as a daily drive in town with stop and go traffic.

I don't want a race-truck, not even close.

But I would like the truck to be more responsive when I step on the gas peddle and maybe even be capable of smoking the tires a little.

The truck does not leak any fluids and it does not smoke.

When driving in town or on the interstate, the oil pressure gauge stays between the "o" and "l" on the gauge and the temp stays between the "t" and "e" on the gauge.

I really appreciate any insight you might have and/or suggestions.

Thanks a lot!
