Engine question
Hey guys n gals, I was wondering if I have to use a rear oil pump 289-302 to put in my truck. I went to go get one today and all the places I talked to said that the 289-302s from the late 60's were front oil pumps and so before I go spending the money I figured I would ask you guys to find out for sure first. I thought I had to have a rear oil pump. I still have the stock straight axle in the front. Thanks in advance...

Let's make sure we're all talking about the same thing. All small block Ford engines have only one oil pump, and it is located at the front of the block. There is no rear oil pump. That said, in certain applications, you may need to use a rear sump oil pan for clearance issues, especially if you're converting to an independant front suspension design. That will require a matchiing pickup tube to suck the oil from the rear sump to the front mounted oil pump. For your original straight axle, it will depend on how high or low you set the engine if you have a clearance issue, but you should be fine with the conventional, front sump pan setup.

You are correct. I installed a 289 and a C4 trans in a 1950 F-1 way back in 1977 and it fit with no problems at all with the conventional front sump pan. No firewall, frame, or crossmember hacking. I'm assuming nothing has changed with either parts over the last 30 years. ;-) It sat high enough over the axle I had no issues. You should be fine.

You have several options, and a lot of the decision will be determined by your fabrication skill level. I like the idea of placing the engine in the truck where it fits best, looking at fan clearance, exhaust, angle, etc., and custom building mounts to have it sit there.

Like I said, you have several options and many diferent pre-made mounts you can buy. The question will always be if the store bought mount will allow your engine to sit where you want it. That's why I always made my own to fit.

I had a 289 in my 55 and purchased a set of SBF Motor Mounts from JC Witney (this is 1985 and they were about all that was around) they worked fine.
Here's some typical ones:

The ones I used were the same as in box #1 on the LMC page - worked great!
