Small budget build

Post  jones on May 19th 2013, 10:33 pm

Hey guys whats up!! I know it's been a while!

I guess I'll build another engine, let me start with what I have. I am putting this engine in my 1984 4x4 F150 with a Np435 manual transmission. This is the old engine out of my 1979. It has a recurved dizzy, and a small camshaft, everything else is stock. The reason I pulled the engine was due to it not having oil pressure at idle and 10-12lbs up. I am hoping that it will only need bearings and rings. I'd like to replace the D3's for something better but I guess that depends on what used parts people offer to sale me!

Just thought I'd get this thread started and let ya'll know I am back into it again! Cheers!! cheers

Nice looking truck, good candidate for a 460!

The 300 works great, but I know if I just build a simple 460 I'd have more power than I would with a built 300. I don't have a high paying job anymore so I hope to use a lot of used parts and make a awesome build. I know if the right people come off with some good parts I can make a strong runner! LoL

Can anyone tell me about changing a engine from auto to manual transmission? I am under the assumption that a 351m bell housing that ran a Np435 will work. BUT!! When I compare the depth of the bell housing to a QuickTime or Lakewood they are two different dimensions.

Also, the truck is a 84 with a hyd clutch and most of the bell housings on eBay have been for the earlier mechanical clutch. What would you suggest me to do?

Ok, I found the right flywheel. (M-6375-z460a) external balanced for my 79 engine. Lakewood says the (RM-8011) will work but they wasn't for sure on the depth. Is there any way to tell about this without pulling the transmission?

If the bellow information is true, I should be ok. Anyone confirm this?

This transmission is 10.8" long and features an aluminum top cover that is retained by eight bolts. The NP435 case is of cast iron.
The Ford NP435 has a 1-1/16" diameter, ten spline input shaft that has a stick-out of 6-1/2" from the front face of the transmission. The pilot tip of the transmission measures ~17mm. The front bearing retainer flange measures 4.85" and the bearing retainer tube is 1.43" in diameter. The front bolt pattern is the symmetrical Ford "butterfly" pattern; roughly 8-1/2" wide by 6-5/16" tall. The input shaft stick-out length is 6-1/2".

The Rm-8011 bell housing has 4.85/4.91/4.685 in. Bore Dia. - 6.3 in ht

I thought now that I have quite racing the truck I would post the final engine build.

Ford recurved distributor from RHP
MSD 6al
MSD Blaster SS coil

The engine made good power but wasn't as "fun" as I hoped, no lopey idle and didn't pull hard past the first 16' on the dragstrip.

Need some 4.11 or 4.30 gears it will pull then.... Laughing

Freshen the bottom end and Put some early heads on it and get the compression up to 10:1 too.

The truck I am putting the engine in now, has 3.05 gears, 31x10.5 tires, manual transmission compared to 29.5x9.5, 3.50 and automatic.

Your going to need some gear if you want it to be fast. 3.05 gears and those tall tire are not good for going fast. Might try running some shorter tires it will help some.

You looking to mud bog or drag race with this thing? Mud bogging you can just use low range and it will be fine, your not hitting speeds like drag racing.

LoL shorter tire,,, thats ass backwards! I'll change the gears down the road, I'm going to swap the 8.8 out with a 9" and 4.30-4.56 gears. I'm not concerned about being fast in this truck anyway. (The NP435 doesn't shift fast) If I need a lower gear I'll drop her in granny low (6.35 first gear ratio) and 4 low.

I'd like to raise the power curve of the engine, I'll be trying to get wheel speed when I'm out playing at the mud bogs. (I guess)

What y'all think?

If I changed the camshaft to a solid flat tappet or would just a little more aggressive hyd flat tappet camshaft do just as good?
Milled the heads to raise the compression a little.
What else could I do to the engine while I had it apart?

I'll probably stick with the headman 1-3/4" headers.

X2 Cams fine for the gearing and exhaust, I'd spend the money on heads.

I hoped someone would reply to my parts wanted thread with some cylinder heads but no luck yet. I hoped to find a set of used Trickflow heads. (d0ves, c8's, c9's would work too)

Found a set of D0ves, they just need to be completely gone through.

What is your thoughts on if I change the camshaft to a Comp Cam Grind 291THR7 Part #34-601-9
Hyd Flat
Dur@.05 I235 E249
Dur I291 E311
Lift I.567 E.551
LC 107
IC 102

I just can't help remember that I felt the last camshaft was just so mild. (It didn't sound or act spunky.) I will be raising the compression and switching to at least D0ves.

IMO your getting a little large on the cam for what you've got.

Smaller is better for what your doing and what you have to work with as long as your dynamic compression doesn't get to high for the fuel you intend to run.

Keep in mind

1) You have less than optimal gearing and big tires.
2) Its a heavy truck
3) Your trans is not for racing !

I agree that I don't want to go too big on the camshaft. That was the camshaft (great fit) the Comp Cam program suggested for my truck. (4x4, weight, cubic inches)

The gearing isn't to far off. Local member runs the 3.05 gears with 35's with that naturaly assperated 528cu I built. Runs 3's in 200ft using 4 high. Where I'm not in no hurry. If I do race it, it will be in the bog pit, 4 low in 3rd gear! Plus I can run 75mph around 3,000rpm.

But it's main life will be to take me to work on and rescue 4 wheelers. (That's my side job) I want it to sound spunky when I pull up to a customers house.
