For pure novelty, I'll probably run the two 950's. I do have a pair of NOS gear drive secondary kits, so I could undo the current mods and go that route, but I may also run vac. secondaries since it will probably run much better on the street. Now I'm writing that as if it is mine when in reality it's my dad's setup. Will he run it on his car and how will it be configured? Who knows. I can say that either of us would love to run around without a hood and having this thing stare back at us.

I run an early MSD 7A and it did a great job dealing with the puddeling of fuel in the intake on street driving. I realize that this is something that will need to be managed. The comment about the intake being prone to some killer backfires...something I didn't think of immediately, but after you mention it- yeah that is something to be mindful of. I do know a guy who had a TR small block that would spin the choke plates over center and get them stuck when it would backfire. This potential liability is just one more reason these old TR just arn't seen often.

The center cap is part of a set I have kicking around. Good eye there Mark catching every detail, even the ones hiding in plain sight.


<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: markjohnson</div><div class="ubbcode-body">That's some serious airflow goin' on there with TWO 950 Holley 3-BBL's! I can see where they have been somewhat converted into mechanical secondaries with the infamous screw placed into the Secondary throttle shaft linkage. That particular early-style Tunnel Ram has the reputation being explosion prone due to that MASSIVE plenum chamber. Please don't think I'm knocking it or anything, but you need to be cranking that motor over with the starter before pumping the gas pedal, otherwise that plenum becomes a giant fuel/air chamber and an intake valve hanging open (or even bent from last summer's missed 2-3 shift!) can result in a backfire of EPIC proportions that will be the subject of cruise night small talk for decades to come! By the way, do I spy a Motor Wheel Spyder center cap on the table there? </div></div>

Now I really like my early MSD 7A- it isn't a 7AL and it doesn't have the bid plastic cover on the side of it. So when I saw this unit here on ebay, I had to have it. The bonus was that nobody else felt the same way and I didn't have to &quot;overpay&quot; for it.

I beleive this was the 1st generation desing of the MSD unit. I know they were around in 1976 and the company started manufactuing systems ~ 1970 so does anyone know when this design first hit the scene?

Note the large heatsink base that the cover bolts to.
