They make a drop bracket for the power steering so it will clear the headers. One more thing, what engine was in your Mav before? If it was a six youll need V8 frame mounts and a Belly bar. I know some guys here just relace the power steering with an aftermarket kn ucle.
I just finished the V-8 swap on my 70 Grabber. I had a 74 Comet 4dr as a donor car. It had everything I needed to do the swap. The only thing I couldn't get to fit was the V-8 trans mount. Had to reuse the 6 cyl mount. I did manage to install a complete cooling system, new water pump, recored 3 row radiator & themostat. All I need is a new exhaust system, headliner & paint job. Then it is complete... Thanks to Mike for all your help to get done so quickly...
The 70 had a straight six. I've got the 74 Maverick that the 302 engine came out of, I'll use the engine mounts and belly bar and anything else I may need. The drop bracket for the power steering is there on the 74 as well. I'm hesitant about putting in the power steering as there is not much ground clearance. Maybe it's the way it's mounted but it did not allow for header clearance, the header was beat to hell to fit around the power steering arm. And what an oily mess, reading other post, I may just keep my manual steering. Coop, why couldn't you get the V-8 trans mount to fit?
I believe you will also need the v8 trany mount. In my car the 6 cyl. trany mount held the tranny too far back. The mechanic had to install the v8 tranny mount to move the tranny forward so it would bolt up to the engine. This also resulted in having the driveline lengthened 1 1/8". I was going from a 250 6 cyl. to a 302. I have power steering and a column shift automatic so I had to use a headman short tube header, part # 88400. It was still a tight fit on the driver side but they were able to get things to work with a little trimming and modifying. My motor was a late 80's roller motor so that might of made a difference. Good luck with your project.
if the ...V8 motor stands...are installed backwards it will cause this same situation....they are (left/right) with an 8" rearend...I have done this swap with a...C-4,...AOD...T-5 and a 700R4 transmission and have used the same driveshaft. I've never had to mod. a driveshaft...the 6cyl. and V8 driveshafts are the same lenght.. ......
Frank, I was thinking the exact same thing. When I got the blue car the engine was too far forward and upon further inspection some one had put the motor stands in backwards. The tranny X-members do set the trannies in the same position so if you have a C-4, whether it be a 6 cyl. or a V-8 tranny mount, they are going to sit the same. Something that has been asked but not addressed is why the V-8 tranny crossmember doesn't fit in a 70. The ears on the crossmember are too wide(70s have a narrower tranny tunnel) and have to be trimmed and once you have it where it will sit up there correctly you will have to drill new mounting holes on one side, pretty sure the drivers side.
I came across the very same problem with my 70 and had to re-use the 6 cylinder crossmember - other than the fact the tunnel is smaller and designed differently, a 71 and later V8 crossmember was never built for the 70 as all came with 6 cylinder engines
Coop, why couldn't you get the V-8 trans mount to fit?[/QUOTE] The hump is to small (narrow). I even tried to elongate the bolt holes. The only way to make it work was to cut the cross member thru both bolt holes @ an angle. Not going to do that cuz then I wouldn't trust it to hold the weight. Maybe later I'll modify the 2 mounts together to make it work. My 70 had the 170 cu in & manual steering. The 74 had power steering. I kept the manual steering...
I took some plate steel the same thckness as as the tranny mount and cut a couple small pcs and welded up the holes and then drilled them where they needed to be. I did mine in about 4 hrs, wasn't that hard just time getting it to fit then welding then measuring again to get the holes right. You could take 2 6cyl. mounts and cut the riser ( the side the exhuaust goes down) off of one and cut the flat off the other, leaving the tranny mount hles on this side, cut hem long on both to allow for mistakes, run bolts through them in the mounting positions to figure where to splice them together and then butt weld the riser on the driver side of the other, essentially making a 70 V-8 tranny mount. Once cut to the right length I would mount them and tack them in place to make sure they were right than pull it and weld it good.
