So on the 94 F150 2wd the stock 5 speed crapped 3rd and 4th gears. I am going to hop the 302 up with aluminum heads and a healthy cam so I was thinking about changing the tranny out to maybe a Tremec 5spd and need any thoughts or anyone who has done it.
Thanks, Paul.

 

Changing the axle ratio as well? I would go 3.73 or 4.10s to help it get off the line better.

 

What hp are you hoping to get out of it, anything over 290-300hp you'll need to tune it, and that isnt cheap on OBDI, unless you know how to, or you have a buddy...that can be bought with spirits.

 

I will change the gears. Probably to 410s.

 

Hoping around 400.

 

They are great until the highway at 85!

 

Maybe 3.73. I believe it is 3.55 now.

 

If I redo my axle again, that’s what I’ll go to. 4.10s have been great with stop and go traffic pulling a trailer, but that 4.5 drive to see my kid sucks! 75 mph is around 3100rpm. I’ve contemplated having a set of oversized tires for the rear just for longer trips.

 

Torque breaks parts and shock loads. A 400hp 302 is not going to make much torque with that little 3" stroke

 

or work with the stock speed density EFI computer.

 

I am with you on that, yet a 400hp 302 will probably have a torque peak around 4500, give or take 500rpm. If after that, badass, keep us informed on the build.

It will act like a cammed Gen 3 GM. Been around those since late 90s.

 

Too much further past that and the block gets real iffy real quick.

 

I am also putting together a 408 aluminum headed roller stroker that may end up in it.

 

That’ll do pig, that’ll do!

 

My dad bought the truck new so it will be passed on to one of his great grandchildren.
