I6 to 302 Question
I am thinking about taking out my inline 6 cylinder (out of my 1975 F100) and putting in a 302 out of an 89 Ford. I know that I will need to change the motor mounts, but will I need to change the frame mounts that the motor mounts fit into?

Something wrong with the 300? What condition is the 302?
Not all 302s are created equal and that '89 if OEM and half worn out might not have any more beans than a good running 300.
Check twice, swap once.
Swerving suggestion

The 300 runs great, it just has very low oil pressure. I am going to take the oil pan off to see if the oil pump is stopped up. The engine doesn't smoke or have any knocks. I am just getting a plan together incase I can't get the oil pressure up. I have a 302 that has been rebuilt.

302 should bolt up except for mounts. A 89 302 is a turd anyway and hardly better than the six.
If you are going through all this, you would be better off with a 95-97 351w, bolts exactly the same as the 302 but has more torque, HP, and longevity due to roller cam and lifters.
My vote would be replace with HV oil pump, and ensure PCV is functional. Use 15w-40 or 20w-50 oil should get you many more years or miles.

My Dads with a 240 had low pressure, he bought it used and abused but looked good. I pulled engine, put in new bearings and seals. Never pulled the head just new valve seals. It was on the road for another 20 years with good pressure.

Hey jswartz84, do you have any pictures of your 302 on the trans dapt mounts you could post? Do you just remove the stock towers and bolt in the kit?
Our 300 has a rod knock and are talking through our options.
TIA.

You do have to change the frame "towers" where the motor mounts bolt to the frame.
There is a BIG difference between the I6 towers and the 302 V8 towers. Both sets will bolt to holes already in the frame.
Look at post #5 in my build thread...... It shows the I6 sitting in my frame.
Then, scroll down and look at post #46... That is my 302 V8 bolted in.

Good luck.
