Its 50 years old

You never know what you are getting until you have it in the garage a couple weeks and get a chance to look things over.

I had to put the oem valave cover on, the chrome one interferes with the carb.

So today I cleaned up the old cover that the PO was kind enough to give me, and pulled off the chrome cover.

This is what I find hiding under the shiny new chrome.

Luckily I have an extra adjustable valve train, so between the two I should be able to have enough parts to rebuild this one. Someone at sometime installed the adjustable rockers, so lucky for me.

For the ones that are learning, like myself; what's going on here?

1966 Mustang 2-Door Coupe
Engine: 1980 302 bored 0.060, so 311 ci. 351 heads, Holley 670 cfm 4 barrel, Eldebrock Torker II 289 intake, Competition Cam 276 duration 490 lift.
Trans: 1966 C4, recently rebuilt
Rear End: 8.8" rear end, 3.73 ratio w/ tractionlok, sourced from 91-94 explorer
Brakes: disc in front, drum in rear. Manual all around, single reservoir
Non-numbers matching

My plan is just to build a decently powerful muscle car that looks good but is a driver not a show car.

On the six cylinders the rocker arms are all on one long shaft held up by a few towers that are bolted to the head.

In the first picture you're looking at one of those towers and next to the bolt it's got a big crack in it.

Most of the sixes come with fixed rockers since they have hydraulic lifters. Someone has added the adjustable ones. Not a bad thing in itself, but when you look at the second picture that hose clamp holding it together is not supposed to be there.

The small sixes ranged in size from 144-170-200-250 ci.

The 144s had solid lifter cams and adjustable rockers.

The adjustable rockers can be installed on later heads with hydraulic lifters and is a good idea if the head and/or block has been milled.

The pushrods were way out of adjustment. Some of them were very loose, some of them were very tight.

Had I not needed to pull the valve cover it may have been a year or more before I found this, probably would have found it when that pedestal gave way or the hose clamp slipped and some bad noise resulted.

One thing great about getting older. A life in prison sentence is less of a deterrence

This weekend Im going to pull the rocker shaft, replace the cracked pedestal, figure out why the hose clamp is there and adjust the valves.

The PO tells me he is no mechanic.

Well, he wasn't lying. That hose clamp is awesome. I'd want to start it up with no cover on it just to see it dance.

Lol I hope I'm wrong but I bet you're only just seeing the top of that ice berg. The hose clamp is awesome. Maybe it backed off one day and it was a road side repair that got made permanent.
