i have a 89 ford f 150 and am wondering if an 86 351w would be able to be converted to efi and the parts from the tired 302 are interchangable with this block. would hate to spend too much money to make it work. i know i need to change the computer which i took with wiring harness from 90 f 350 with a 351 w. also would like to install dual stacks coming from the floor of my box is this alright to do?

 

As far as i know most brackets should be interchangable.or easily modified. You will need to get an upper and lower intake to fit the 351 as the 302 intake will not fit. The 86 motor should be able to be converted to efi but you have to make sure that you use a camshaft that is computer compatible or it won't run worth a darn. Good luck!

 

P.S. Stacks through the box should be no probs.
