I just went outside - it is just a single line and a one way valve (left over from taking everything off) from the carb's full manifold vacuum source to the heater control. The only other vacuum in use is for the distributor and that comes off of the carb, too.
And for the master cylinder it looks like it is just the stock hard metal line that went right into the Edelbrock intake.
So apparently I didn't have to use adapters. Too many years ago to remember exactly what I did w/ that Edelbrock, though.
Not much help, sorry.
Thanks. I was working on it last summer, near the point of putting the new intake on the, had to really hunt around to find the correct looking water outlet (heater hose) in the front and was about to get the vacuum ports sorted when family emergencies came up and everything else was on hold for some time.
Part of the problem is jeep catalogue don't list a lot of small parts, then go to s10 side of the fence it's a little better but again no part numbers to check.
When I had to stop I was trying to figure out if the was a way to use the ports off the old engine. After leaving it alone for so long I'm trying to get back to working on it.
Oh, one weird fact, you know how gm screwed jeep and other companies they supplied engines to by selling outdated motors and keeping the best for the gm production year. (1984 XJ has a 83 engine)
This also lead to the weird 1986 2.8 block with bigger journals and mechanical fuel pump.
Big deal was about the cylinder heads, 1985 gm improved the design (used until 1995 on the 3.4) and they were supposed to be on the 85/86 jeep 2.8, even if the block was 84-85.
I knew someone with a 86 with the improved block, I had wanted the cylinder heads if they were the new design, ran the casting # they were the old gm stock and not the improved design.
Rebuild catalogues list these motor main difference as the cylinder heads, apparently gm made a few more buck by short changing the companies they supplied for.
Just a weird thing I found out about, as random as these 2.8 motors are I've no idea if the 86 I saw was the exception or the rule.
