Does anyone know if the 351 uses the same size throttle body as a 302? (non lightning) If its bigger, do you know if it can be adapted to a 302? They look like they would work? I know there's tons of these in the junkyard and if the size is bigger I may try putting one on my truck.

yes it will work . during my truck work i took the one of our shop truck and put on mine . it was a 5.8 l. i dont think it is any larger diameter id then yours tho .

 

one issue you need to keep in mind that even if you put a larger TB on it is still restricted by the stock size of the plenium behind it . this will need ported and polished to the size of the TB or larger .

 

here is some info i found . will bolt to stock TB with no mods to plenum. price is $287.00 + S&H

Ford: 1987-96 5.0L-5.8L F150-350, twin 61 mm, 50-state legal, cast aluminum, performance throttle body

This Edelbrock high-performance throttle body is part of a winning combination for today's late model 5.0L-5.8L truck enthusiast. This twin 61 mm throttle body is ideal for stock manifolds and produces approximately 15 percent more air flow than the production throttle body. It's also 50-state street legal for all 1987-96 5.0L-5.8L F150-350 trucks. Gaskets are included.

 

Thanks Ray,

I've seen the edelbrock throttle body, but I figured If the 351 TB was bigger than the 302 It would be a cheap upgrade. I see in your sig that you are planning to get an edelbrock...let us know how you like it.

Anyone else using the edelbrock throttle body?

scott

 

probably wont be anytime soon . for that or the chip . going to try to get the pulley's tho asap . then will save up for the TB. then the chip.

 

There is a guy over at the NLOC boards with both throttle body and intake for sale. Go to NLOC.net and check under MISC parts.

I just noticed it the other day and he didn't have any offers yet. It should be easy to spot.... I can't remember the thread title, but it caught my eye.

 

I saw where edlebrock sells a twin 56mm & twin 61mm tb for 302/351. Does anyone know the stock size for the 351w tb w/speed density? (my truck is a 94) Will a tb replacement give me more low-end torque? I'm not interested in high-end hp as I tow a boat and need the low-end tq more than the hp gains. I'm planning a K&N drop-in with a modified airbox. Also, does anyone have experience with ignition changes? Will a Jacobs or MSD give me more torque or are they better for high-end hp?

Thanks!!!

 

i checked my TB size today . it appears to be 53 mm . so either of the edelbrock TB's are larger . as far as the numbers go (dont know if it is high end or low end ) i believe it is about 20 hp and 15 to 25 tq. , i'd like some info on the msd ignition parts also i am thinking about that too.

 

Thanks for measuring that for me Ray. I'll measure mine today to see if there the same size...

I was never a big fan of changing the ignition, i think ford is just fine. if you go wheeling and something brakes out in bum**** what do you do for parts. at least you can go to a dealership or napa or something for stock parts.

ignition? i think ya got the wrong thread curt

i agree tho . i plan on getting an accel coil and accel tfi . but thats as far as i'll go

 

i just mentioned it because somebody mentioned it a post. might have been you ray. something about msd. curt

 

With my Jacobs I can switch to stock in about 1 minute, and 20 seconds of that is pulling the hood release and opening it up.

 

2che, guess that will work.
