I am currently swapping my tired 300 straight six for a 302 in my 77 f150 and i'm in need of help. I am uncertain if i need to change anything along the line of engine mounting.

 

I'm almost possitive they used the same tranny's so everything should bolt up. The only caution is if the 302 is EFI you'll need to make sure you rout the whole computer system or if its Carb you'll need to make sure you have the brain box with it. Also just on the safe side make sure there's enough room for your radiator but everythign should just bolt up. Engine mouts are all I can think of. P.S. you may want to make sure any pumps (brake booster, powersteering, ect. will work with your new motor in.) Good Luck!

 

Thanx, its a big help!

 

Brain box in a '77?

 

yeah i didn't think there was a brain box either? but the mounts/ perches are the same... that i found out, they just need to be moved back about 3 inches.

 

It's not really a brain box, it should be a duraspark II ignition module.(Man I hate those things!)
