(1) 1989 E-150, 302 injected/AOD
(2) 1984 E-150, 351W H.O. carbed/C-6
Okay, the injected 302 in my 89 E-150 has just about had it. I am also tired of screwing around with fuel injection. I need to replace the valve cover gaskets anyway, and if I am going to go that deep into this engine I am just going to pull it.
I have a rebuilt 351W in my 84 E-150 that gets better gas mileage than my injected 302 (and with a C-6 instead of an AOD to boot). I am going to swap the 351 into the 89 and swap the 302 into the 84.
I am thereforee going to do two swaps: the 1984 carbed 351 into the 1989 injected van, and the 89 injected 302 into the 84 carbed van. I will be switching the 89 from injected to carbed and I will be switching the 302 from injected to carbed.
I think i have all the necessary concerns sorted, but i would appreciate any comments or suggestions from people more familiar with this stuff than I am:
351W to 302 swap: Motor van 2 to van body 1
(1) The 351W should bolt right up to the 89 AOD so long as I use the flex plate that is currently bolted to the 351. The 89 AOD is not ocmputer controlled so I should be fine
(2) I will need to get a fuel pressure regulator to reduce the fuel pressure from the electric pump from 40 PSI to 7 PSI. like this one
The 89 should already have a fuel return line so I should be set.
(3) I will need to put together a non-computerized ignition system (no problem. I have most of it in spare parts for my 84 anyway...)
(4) I will need to modify the exhaust to deal with the difference in the width of the motors (351 is 1 inch wider than the 302) I might tackle this by just swapping the y-pipes between the vans
(5) I will need to adapt the 351 carbed emissions to the 89 van. Shouldn't be a problem, all i have is PCV and AIR injection and a catalytic.
(6) I will need to use a Lokar style kickdown inkage for the transmission. But I already have one on the 351 anyway.
(7) All the accessories (P/S, A/C, alternator) and the serpentine belt system should bolt right on to the 351 from the 302, right?
302 injected to carbed: Motor van 1 to van body 2
(1) The big one, I will need to replace the induction system and the cam. Aftermarket carb intake manifold (I am leaning toward edelbrock performer or Offy dual port, I already have a couple carbs to play with) RV style cam for the 302. I have read that vans got the high output 302s, will that make a difference? Do i have a roller cam? Would it be cheapest to get another roller cam (no need to purchase new pushrods)? If I don't have a roller cam would it be cheaper to get another non-roller cam?
(2) mechanical fuel pump (might require replacement of the timing chain cover. I need to replace the chain anyway.) This should swap over from the 351.
(3) same exhaust and emissions issues discussed above.
(4) the 302 should bolt right up to the C-6
(5) the 351 pulley system should bolt right up to the 302, right?
(6) Distributor? Anybody out there have a distributor from a 302 van or truck? I want it curved as close to a van spec as possible. I don't want some aftermarket hi-po mustang dist. curve.
Am I missing anything? I should have 95% of all the hardware I need to do this swap since I have two complete and running vans sitting side by side.
The next motor swap I am going to do will be in my 84 again, in which I will swap from the 302/C-6 to an electric motor and four speed overdrive manual tranny!
