Question

i was wonting to put a 302 in it put did not know how much work it was. and did not know if the trans. and the rear end would be strong enough. i was wondering if i should rebuilt the inline 6 or go with the 302

Answer 1

it will fit, but need new motor mounts and brackets, plus carb linkage.

Better to add a 4 barrel and headers to the six, great sounds and pulling power :)

Answer 2

The 300, 302 and 460 all share the same bell housing and bolt patern. However, the engine mounts and location of is different and as such the trans locates in a slightly different place, which changes the driveline length. Go to the junk yard with a careful eye and a measuring tape.

On a different note if you are wanting to change the engine to get more power you should know that the inline six produces as much or more torque than the eight and with very little modification will make just as much if not more power and it's just cool to blow away all those V8's with a six.

Answer 3

those 2 are not to any extent further even remotely an identical engine or same motorized vehicle. F150 V6 is a a million/2 ton truck. The V6 is extremely weak. F250 is a three/4 ton truck. The V10 is a sturdy engine, in spite of the undeniable fact that this is not as sturdy because the Powerstroke diesel. If I were paying for both truck, i might want to purchase the 5.4L Triton V8 for the F-one hundred fifty and wait 2-weeks till the 2008 F-250 6.4L Powerstroke diesel arrives on the broking.

Answer 4

The 300 6-cyl & 302 are interchangeable, should be a direct swap.As the bell housings are interchangeable.

The only difference on them older ford small blocks is the infamous 351 Windsor which is about 1 - 1 1/2 inches wider than the other smallblocks.

It can also be used as a substitution ,just have to modify the exhaust to accommodate for the extra width.

Answer 5

The Inline 6 is the best truck motor Ford ever made, at least in the aspect of high mileage and reliability. It really depends on what you want to use the truck for. If you're looking for speed, the 302 will be your best bet. If you're looking for reliability, low end power, and you want to pull trailers, definently go with 300 - 6.

The trans. and rear end are the same in your truck as in the V8 trucks. For more help, try going to fullsizebronco.com and do a search for V8 swap, or something similar. I'm a member there, great site. My ID is blackbronco92 if you'd like to PM me for help.

Answer 6

For the record, the bellhousing bolt patterns on the two engines are identical. But the intended gain is hardly worth the labour required for the swap, unless you have a "donor vehicle" at your disposal. The 300 cu. in inline 6 is a good engine with plenty of torque, that will run forever when properly maintained.

Answer 7

No the bell housing will fit. Your ring gear or flywheel /clutch may not. If they don't the bell housing Will not have the diameter spacing for your starter. You'll loose a lot of "lugging torque" however. The 302 is a high rpm. car motor not suited for the "grunt" needed for a pick -up. I' look for another 300 cu. in. 6 or smaller 6. I know for a fact you'll get better fuel economy!

Answer 8

They used to would interchange, but I can't be sure on the '81. You may run into a issue with motor mounts, on the older trucks the mounts for the 302 set the motor farther back than the six banger.

Answer 9

im a big fan of the old straight six 300, then last a long time, are simple to work on, and the heads are much easy and cheaper to rebuild, if its a automatic its a standard c-6 trans mission not a lot to them, it they should intechange and fit, id put hte money in the c-6 they have a lot more tourque.

Answer 10

I don't think you would have to. Try going to www.fordtruckworld.com and ask your question in the forums there. Those guys should be able to tell you.
