78 F150 390 swap
hello all i've search on this swap. i have a pretty good idea on all the items i need to complete this but the only thing i haven't seen is what headers will fit? i have a great running FE motor not sure if its 390 or 428 haven't checked the stroke but it does have the Cobra jet heads on it. i'm pulling it out of my 61 F250 Mud truck and building a more universal trail/mud truck out of a 78 F150 shortbed that is street legal. i have headers on the motor now but not sure if they will work in the 78. they are hedmen headers p#89120 they are for 76 F250 4x4.
So far my list of items are:
Frame horn mounts FE or inline 6 i still need to find
FE Bellhousing which i have.
headers if mine dont fit.
i think its going to be pretty easy but please correct me if i'm wrong and if there is anything else i need.
the 78 is a 4 speed same as the 61
thanks for the help

I just got done swapping out a small block for a 352 in my 78 F 250 4x4 and it went in easily. I only needed an FE frame horn on the driver side and slightly modified the passenger side frame horn. I used hooker headers for an early-mid 70s F250. I just have to use a mini starter and the header collector on the driver side is very close to the front driveshaft

Alright was able to work on it tonight. i had to drop the whole drive shaft out put a few bolts into the header in to hold it up went to see how much i was going to have to work with and wont be able to do anything about it. its right where the yoke is no bending could fix this. the ones i have are Hedman street hedders 89120. they are for 76 Ford F250 4X4 4 speed. to me they seem like they hang down low compared to the ones on my 77 F150. i'm thinkin i might be stuck with the stock manifolds
