78 running gear in a 69 LWB? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ogier · 06-01-2005, 07:40 PM

Greetings all,

I am about to get a 78 cheyanne that is wrecked. It has a 454/TH400 in it.

I was thinking of swapping out the rear end(14bolt) and the front disk brakes into my 69 C20.

What do I need to be aware of in this swap???

ANy thoughts,
Ogier

motor/tranny/front end will work, but i am not sure about the rear end. are 3/4 tons coil sprung? cause if they are then it wont work. i think i read that the width is different. but let a pro help you with the rear end

Super Duck · 06-01-2005, 07:44 PM

eng mounts, and possibly spring mounts. the rest is nothing

I am hoping to get the 3.27 gears in my truck to replace the 5.13's that it currently has.

I haven't decided if I am going to replace the caddy motor or not with the 454. I might have to save the 454 for a street rod. Maybe a T-bucket or something...

Shouldn't be anything a welder won't fix.

Well, I have 3 welders and a torch. A bunch of hammers ranging from tiny to all out adjustment size...

Perhaps this won't be so bad.

I am thinking of stretching the frame out 8" and adding it to the cab behind the seat while I am at it. Seeing as how I need to have my driveline altered, it seems like a good time to do it.

Hey Pont and Super Duck, Ya all wanna come help?

This is what I want to do to my 69 as soon as I get my new shop opened.

hmmm???

I could be wrong, but I don't think the newer Th400 gas pedal kickdown will work on a 69 pedal. Might possibly have to buy a 68-70 kickdown from a board vendor to make it work??
