Swap a Motor?

Ok, heres what I need to know, my truck is a '79 f-100 custom with a 300 inline 6, I lost some rings, so I am thinking of rebuilding the motor, then a friend told me he has a 400 v-8 that is in real good shape and he will sell it to me for $200, now will the 400 bolt up to the tranny (3 speed auto with revirse(C 4 I think)

NO.

The 300, 302, 351W,Transmissions are inter-changeable

The 351M/400/429/460 transmissions are inter-changeable

no, the 400 will not bolt in, bellhousing is different, 351m 400 429 460 share same pattern. You have the small block pattern on your 300.

Remember, just because a transmission will "bolt up" does not mean it is configured correctly internally (shift points and load capacity) for your engine of choice. Transmissions must be matched to the engine or strange operation and quick burn up will occur.
