I have a "92 F-150 4X4, E4OD trans, and am installing a 351w engine with a dual plane manifold and a 650 holly carb.
My ?? is, what cam would be best for street performance as well as towing (ocassionally) and fuel milage. I'm thinking low to mid-range torque is my best choice, but just not sure about the advance duration and what torque converter would be best suited.
Can anybody assist me on this combination?

Thanks, HAL_419

 

E4OD with a Carb'd motor...I'm assuming that you're not using (and maybe removed) the engine harness and PCM, if so what are you using to control the trans?

Is this going to be a roller cam?

 

Hello Blurry94
This is a little better discription of what i'm doing, the only thing i'm not sure of is the rear gear ratio. Whatever was stock on a 92 4X4 with a 302 EFI. I'll check it out when it gets a little warmer
(7 deg.) at present. And windy

I have a "92 F-150 4X4 short bed, E4OD trans, 31" tires and am installing a 351w engine with a dual plane manifold and a 650 Holly carb, roller tappets, Windsor cast iron heads, with S.S headers.
My ?? is, what cam (flat tappet) would be best for street performance, as well as towing and climbing sand dunes(ocassionally) and still maintaim respectable fuel milage for a daily driver.
I'm thinking low to mid-range torque is my best choice, but just not sure about the advance duration and what torque converter would be best suited.
Also, any comments or suggestions on the trans performance (strength wise) for this set-up would be appreciated. I'm putting in a controller from Baumann Engineering to handle the electronics on the E4OD trans since I will be eliminating the factory engine computer setup.
Can anybody assist me on this combination?, and possibly explain the stall speed of a torque converter as well as the benefits of it.

Thanks, HAL_419

 

Okay, if you're scrapping the EFI the computer is NOT going to know what the engine is doing, and won't be able to tell the trans when to shift. You will need a manual or a C6 auto if you want to go carb. That or a stand alone trans computer. You might be better off to go get the EFI stuff from a '92 truck in a scrap yard. Make sure that you get the computer too, and also make sure it has the E4OD trans as well.

 

Hal,
I would definately recommend a custom grind cam for your combo...I have seen many go this route and have excellent results.
The ideal converter is one that stalls at the eniges peak torque, but in some cases that's not good for towing, so a "lock-up" converter with a lower stall may be a better option (the cam profile will make a difference here).
The E4OD can take alot of abuse when prepped properly, common upgrades are valve body, converter, and a better trans cooler. However, if you're looking for an E4OD that is "bullet proof", I would recommend a Monster Box from Factory Tech. They have a 2 year warranty and can be purchased through Jasper Engines and Transmissions I think.
