Re: 1988 Gmc crew cab build
 

did not have to mod the fire wall , with the motor mounts I got it sits on the stock chevy fraim horns and didn't have to move the trans cross member , just had to use a trans mount for a 4 speed auto to get the mount to bolt to the 47rh trans

Ok have a have a question about these trucks. The vacume line the run the heater controls , that is like the size of a pincle lead , dose it also feed the cruise control ?

Re: 1988 Gmc crew cab build
 

I'm surprised that nobody has chimed in yet. Mine doesn't have cruise control so I'm not sure. Sorry.

Re: 1988 Gmc crew cab build
 

Man I tell ya all this little stuff to make this motor work is killing my time frame and pocket book :(

Re: 1988 Gmc crew cab build
 

I hear ya. I thought about doing a 12 valve or 6.0 swap. But then I decided I have a good 454 already in the truck.

Re: 1988 Gmc crew cab build
 

Just read throught your forum. This is going to be a killer truck. Seriously dig the interior! How far are you going to lower it? Whay other plans do you have for it?

Re: 1988 Gmc crew cab build
 

Going to do a 3,4 drop on it still want to tow and put a small camper on it

Re: 1988 Gmc crew cab build
 

You can tow and put that camper on it even better with a bagged truck. More overall control and easier to load and unload.

Re: 1988 Gmc crew cab build
 

Well still working on the little stuff to get this thing rolling , I am down to a fan shroud , and shift linkage and the exhaust finding I will have to custom make a down pipe out of a 1st jen pipe them we will make some noise.

Re: 1988 Gmc crew cab build
 

Well after having to put a new lift pump on it we have a running truck again, wow what a lot of little **** to make this a runner, Had some kids tell me they wanted to do the same thing to there truck I told them they need at lease $5000 and time to do this swap, now just to get some exhaust put on it and start driving it . Here a pic with the new grill and hid head lights

Re: 1988 Gmc crew cab build
 

Looking good. I would recommend dropping your tanks, removing the electric fuel pumps and extending the draw straw if you haven't done it. Keep us posted with updates. :metal:

Re: 1988 Gmc crew cab build
 

all read did the tanks

Re: 1988 Gmc crew cab build
 

Ok. That tan interior looks really nice.

Re: 1988 Gmc crew cab build
 

well did some short trips and all went well so tomorrow I will put 100 miles on it driving to work and home hope all go's good the boss will be pissed if I am late

Re: 1988 Gmc crew cab build

Re: 1988 Gmc crew cab build

Re: 1988 Gmc crew cab build
 

well after the trip today I have some thing to work on , regear the rear diff 4.10's way to low truck only will do 55 , new cooling fan thats not bent , fan grazed the radiator and now it leaks , and service the trans I think the filter is some what pluged up , shift good at slow speed but on the freeway slips in 3rd at high rpm , and there is some random knocking noise from under the truck
