Title: 87 SBC accessories layout?
Post by: Gearhead1 on January 19, 2009, 09:22:29 pm

I'm putting a '95 5.7 TBI into my '87 SWB. Stupid me...threw out the 305 TBI that was in it. This project has been mothballed for a few years, so I've lost track of what went where etc..To make matters worse, I dont seem to have or remember there being an air pump, but the hatnes manual says there should be one.

Does anyone have a link of where I could find an illustration or photo of the accessory configuration on these engines? Would anyone have a photo of an '87 engine bay they could share?

Thanks in advance
Gear

Thanks guys. Neither photo looks familliar though. The alt bracket indicates it can only go on the passenger side. The hoses on the steering pump indicates that it goes on the drivers side. I'm unclear as to what I'm missing for the air pump assy or if there was an idler. This truck doesnt have AC, the sepentine belt is narrower and has one groove less than the '95 (So I'll have to change the alt pulley I guess) The power steering pump uses a standard v-belt.

Frogman, you wouldnt have a pic would you?

Thanks very much guys. (If I had access to an '87, I'd just ask to take a peek of course)

Is yours a compromise of a V-belt and a serpentine?  If so I have that on my pickup.  It actually isn't a "serpentine" setup.

Why can't you use the setup on the 94?  It is a much better setup.

Perfect, thanks Frogman!

Capt, I guess I could, but I wasnt sure if I could get a belt size to work. (95 had AC which is gone now) Do you know if a 95 air pump will work with the harness / comp (prom?) in the '87?

Thanks alot guys!

Capt; I honestly dont remember if the 87 had one. I dont have an air pump for either...must have had a brain fart and scrapped it with the donor truck....duh me.

Thanks for the photos Don

My old '87 didn't have one when I got it, nor show any signs of ever having had one like exhaust manifolds with the air tubes or brackets, etc.  It did however have an extra place for a belt on the front of the water pump pulley.

Sheesh...I never concidered there was never one to begin with....I AM QUITE POSSIBLY RETARDED!!!!
 :-[ :-[ :-[
Come to think of it, the exhaust manifolds didnt have those little tubes.....I'm an idiot. (hanging my head in shame)

Thanks for the picks of the alternator details though.
