i posted this in the ford board also, just trying to get some answers. thanks i just meet this guy with a 73 ford with a 351m that was taking out of a 78 in place of the 390 that came in it. he's had the truck awhile and has never had the tranny bolted down and it finally broke one of the motor mounts. switched the motor mount out last night and i'm trying to figure the best solution for the tranny. the tranny is a auto also. i'm not sure if the tranny was swapped with the engine are is a 73. by the look of the mount bolted to it i would say that it's the 73 tranny


the problems is obvuois that the tranny flopping around caused the mount to break. the tranny is about 2'' forward of the mounting holes on the cross member, i'm guessing that the 351m has a shorter block than the 390 does.

did the 78 have a different style crossmember than the 73?

i can't just move the crossmember forward to match the holes on the tranny cause the control arms are bolted to crossmember and the frame. it could happen but i would envolve a some new brackets and such welded on.

were the frames basically the same for a 73 and 78?

his solution is i just weld the plate coming of the tranny bushing to the crossmember. i'm not really into that as much as i am trying to figure a way to do it right.

any info you can give would be greatly appreciated.

Well, at least that would be a step forward. You could do a plate like the Hi-Po guys do to tie the tranny & engine together a little better & what about a crossmember at the T-case?

i'm not saying what he wants to do want work. he's just looking for a quick fix. the t-case member is a good option. he doesn't really wheel, it is more of a daily driver slash hunting truck. and with the season coming around like i said he's looking for a quick fix. i was just trying to a find out some options for him.

just couldn't pass it up. hell i have to pull out my front axle and get the rockwell in it this weekend, so i am pretty much up to my ass. i bet i will have the only 88 land cruiser around on rockwells. i might just hook brian up with a deal he cant pass up on. i have a auction to go, i hope the stuff goes cheap. i do have the cruiser axles getting ready to go under 2 zuk with 36s. mike
