Moved motor back 1"1/4 tonight. I did not like how close it was going to be to the radiator or how far is was from the firewall. Should help weight transfer a little anyway.

Re: 71 C-10 Big Block Swap
What mount bracket is that? Will it let you go 3" back?

What is the benefit of those....I like the way they look. Stronger I guess since they are tubular. Are they easier to install the engine ?
|
Re: 71 C-10 Big Block Swap
Many Reasons. For one thing they are much cheaper than oe 72 up mounts. They are 129 for the mounts and the stands and they swap you to a car type mount so you can run solid mounts if you want. I would think they would help a little with hedder clearance and they should be easier to install.

Re: 71 C-10 Big Block Swap
thanx I'm putting a caddy in mine so when I slide things in I thnk the linkage will be a good point to determine how far forward/back the motor need to be?? I'm going to have to make up a drive shaft anyway....

The cab isn't any good. I have another cab to use that i'll have to do a better job of notching the firewall. |
Re: 71 C-10 Big Block Swap
Good looking 454s.
We just put a '74 454 from a C-30 into my '71 lwb stepper. We had to use the BB mounts out of a '75 to get the header clearance for the style hooker headers I have. This is not a power machine though, it is hooked to old style 4 speed transmission with an open 3.73 rear. We could not use any of the pre-drilled holes and be able to mate up to the transmission. I did not realize I would have a heat soak problem with my starter running headers so now I have to get a mini starter. I should have though since I know others have had the same problem. We used the BB radiator shroud out of the '74, but had to modify it some to clear the crank pulley, power steering pump and alternator. I still have not got around to taking pictures, I guess I better add it to my to do list. Danny |
