Re: motor swap ???

you need a little...

the correct motor mounts (located in the correct v-8 location)
correct fan shroud
possibly a different radiator (the v-8 will need a larger radiator depending on heat output 3 core rad vs 4 core)
possibly trans crossmember relocation
possibly longer driveshaft


I think that is about it. The reason I use possibly in front of most of the items is it depends on what you have.

Re: motor swap ???

Yup got most of that didn't think about the drive shaft tho. I'm running electric fans on a new aluminum radiator so fan shroud won't be a problem. Just haven seen the mounts for a v8 of that year on a truck yet seance mine had a straight 6 thanks for the info. Looks like I'll be fabbing something up

Re: motor swap ???

You can get a pair of motor stands for about $20-$25 in the parts forum. It would probably be a lot easier than fabbing them.

Re: motor swap ???

I sent you a PM on the problems you will nun into with the swap. But there is a light at the end of the tunnel. I have posted a lot of pictures of the problems you will have. So go by and check out my build. I changed a 292 for a 350.
