Engine Upgrade

I have a 79 f150 4x4 that came with a 300ci 6 cyl. and a D18 transmission . It is my understanding that a 351ci or 400 ci engine will bolt up directly to the bell housing. Am I correct in assuming this swap?

I would go with a 351W, cheaper performance parts and more to choose from.

Plus, the newer 302, 351w blocks are roller capable so you can use a wide variety of roller cams. Performance parts are relatively inexpensive and plentiful.

Thanks for the info should I stay with any certain years when I look for a motor? Or are the newer ones better?

You will need to move your engine perches toward the firewall. The mounting holes should be in frame/cross member. You may need to change your radiator, depending on where the inlet/outlets are. Alternator, starter, p/s pump, throttle linkage, distributor, etc. will need to be changed.

And you need a 4x4 oil pan. Anyone, correct me if I’m wrong, a fox body oil pan will work if one cannot be located. Been a few years but i seem to recall that i had to use one for my Bronco2 v8 build.
