1957 454 GMC Pickup Project

Hello,
It's me again, I just signed up as a new user and would like to get started right away with a few questions. Again, I'm an absolute novice, and that would be a compliment at mechanical work. However, as a pay back, I have 20 years computer experience that I'm willing to share.

Please Note: I'm not really sure what it means to "Post a Pole with this question, so I did it just to see what it means. Go ahead and ignore it if it doesn't make any sense.

Anyway here's is what I'm attempting to do. I have my wifes Grandfathers 1957 GMC truck. It is all original with a 6 cyl and a 4 speed automatic Hydromatic transmission. Maybe you know it, it doesn't have any park, you just put in reverse when you want to park it. I runs well and I have most of the body done. The interior still needs to be painted and the bed needs new oak.

1st Question:
Am I nuts to disassemble a truck that is all original. I have what appears to be a really strong 454 engine in a 1977 One Ton truck that I would like to have put in it. So, I would take out the six and put in the 454. Then I have a 4.3 motor that has 50,000 on it out of a 92 Jimmy and I thought I would have that put back into the one ton.

I've had people tell me that they would never change a truck of that vintage if it is all original. That the value of the truck would really go down. I would keep all the original stuff ie motor trans, rearend ect so that it could be reinstalled later if I or possible the new owner (which would only happen if I was dead, and then it would go to another family member).

Question 2:
What would your suggestions be as to what would be a good vehicle to use the 454 with.

Question 3:
Is anyone aware of a company that would sell motor mount kits. ie going from the current 6cyl to the 454, I think these would help keep the cost down. The local mechanic isn't aware of any and he said that it would be very expensive if he would have to fabricate them.

Question 4: (and then I'll stop, I promise)
What Transmission and rearend ect would be a good match. Any other sugguestions would also be welcomed.

I'm not really sure what it means to "Post a Pole with this question, so I did it just to see what it means. Go ahead and ignore it if it doesn't make any sense.

Thank you for you time in considering my questions. I really appreciate the chance to talk to all of you.
Sincerely,
baydr

Wow! That's a lot of questions. I also have a complete & original 1955 Chev, 1/2 ton Big window truck and was thinking about doing a 454 swap.

There are aftermarket engine X-members that you can install but it's recommended to box in the frame for added strength. Those old truck frames & brakes probably couldn't handle the added weight from a big block.
or
You can use various front subframes from a donor car-do a search, there are quite a few posts on this site regarding grafting a later model subframe.
or
You can spend some $$$ and buy a complete aftermarket independent front suspension but you will also have to box in the original frame rails to increase the strength.

As for keeping it original, that's really up to you. I'm sure other members will defintely voice their opions on this.

i have a 56 chevy truck that was all original when my dad got it, but when he had it, he swapped in a Mustang II front clip and got rid of the original motor, trans, and rearend....

i see nothing wrong with building it however you want to. by starting with a nicer truck, you have less repair work to do which means more money for other stuff....
