I'm not Mike, Barb, but I'd venture to say that it's for vacuum.

vacuum? for what? I have 4 vacuum ports on my carb for the pcv, dist, master cyl., and tranny. what is the other vacuum?

Barb, if it is this hole it is for vacuum. The manifold will take a wide range of carburators and not all will have all the vacuum ports.

Actually a couple of the ports you mentioned on the Rochester were probably for the choke pull offs. In many cases (like my stock manifold) there is an additional vacuum T located in the rear runner for a vacuuum sourse for the AC doors and cruise control.

To answer your question it's fine to plug the hole if you're not going to use it.

thanks mike and ntf. appreciate it.

You could use it for power brakes too.

Well, here's a bit more progress, the TH 400 is rebuilt and ready to go behind the engine.

I stoped by the body shop a couple of hours ago and there is still steady progress on that front. The front clip, doors and tailgate are done and he'd starting on the quarters. He's got the body line in front of the wheel and the at the top of the door matched up and getting ready to start on the back of the quarter. I'm very happy with the quality of work, and the pace it's going.

the body looks great and so does the tranny.

With the El Camino in the body shop I've been spending my time the last couple of weeks detainling and painting interior parts. The wheels also came in. The really big one though is that the El Camino came home today after about 4 1/2 weeks in the body shop. The body lines now match up and 27 years od little dings are gone.

I really happpy with the work, and especially the turn around time (anybody who has had a car in body shop purgatory can relate )

love the body work. that front end looks really good.

Nice Mike.Won't be long now before your cruising to the hot dog stand for cruise night.

Thanks Barb, Gary.

It will be nice to start getting some of the parts out of the way and on the truck where they belong.

The change in the lines came out great, Mike!!! When a body mod is done right, it looks like it came from the factory that way...The car looks stock. Very nicely done!!

Yeah Dave I couldn't be happier with the work that Steve did on this. He's got some neat projects of his own and is just a heck of a nice guy to boot.

Only problem is he's about my age, and I hope he's still around when I'm ready to do a couple of other projects down the road he's talking aobut moving back to Missouri at some point.

i going to be doing the same style ac setup in my 78 monte, i sill gotta yank out the old ac system, ive got the block off plate. now just gotta find time and money to finish the parts list.
