Help me pick a cam

Post #1 by Broncomike » Tue Jul 07, 2020 2:39 am

I've been reading the FAQ till my eyes get blurry and I know enough to know, I don't know enough.

I picked up 95 engine to replace the late 70s engine in my Bronco. The plan was to clean it up, throw some gaskets in it and put it in with an Offy C, 2bbl and HD manifold. Now I'm thinking I should probably replace the fiber timing set, as long as it's out and easy to work on. I've never had any luck getting them off with pulling the cam. So might as well replace it if I'm pulling it anyway.

Here's what I'm looking for, I'd like to get up to highway speed a little quicker and be able to hold a hill with a small trailer or boat, 1500-2000lbs tops, at speeds around 50-65mph. Which is in the 2300-2500rpm range for my combo. I almost never rev past 3500rpm now and thats fine with me, if I made a little more power up to 4000 that would be a bonus. Truck is about 5000lbs with me in it, has a rebuilt C6 with a stage 2 shift kit and stock convertor. 3.55gears and 33in tires.

I'd like to avoid head mods, maybe a stock rebuild or reman head, depending what it looks like when i pull out. I'm trying to keep costs down and for my use, I don't think it'll be a huge help. I do have a 1975 carbed head as well.

I also have a holley built ford 600cfm(I think) 4bbl that I could use or could source another carb if it warrants it after a cam swap.

Any suggestions would be appreciated. Cam choice or otherwise.

Schneider 131H cam, though im sure Paul will be by shortly to add more.

The Schneider 131H is a good choice.

Keep the 95 head. The 75 head will drop the compression too low.
The 95 head has the extra bolts holes to better support the EFI exhaust manifolds.

You don't need a 4 barrel carb if you never rev past 3500 rpm.
An Autolite 2100 either a 1.21 or a 1.23 should work well

I was looking at the 131h in the FAQ, you think it will have any negative effect on off idle torque?

I've got a 1.21 2150 and a 275cfm Holley that I'm going to rebuild and play with. Think I should install my current intake and exhaust for break in, so I know it will fire up and run?

We don't see any affect on off idle torque until the intake and exhaust overlap approaches zero.
The 131H has a -10 degree overlap and will provide a smooth idle and plenty of low end torque.
Besides You have a torque converter that stalls well above idle so off idle response doesn't matter.

Do the Holley first...


...because once you do the Autolite you won't go back to the Holley, and you'll marvel at the genius behind its design.

Im running the 140H in my bronco. With a standard NP435. The rpm range is 2400-6000. I was informed by members here that that range is for a 240. In a 300, the whole range moves down by about 1000 rpms. I have tons of torque right off idle. Going from a stop, up a certain boulder strewn hill in moab, I got all four tires off the ground.

There is quite a bit of diff. between your rear with 4.56 gears, and Broncomike's with, iirc, 3.50 rear gears with a c6.
