Title: Mickey Thompson lightweight hemi-head runs again...
Post by: cjshaker on March 09, 2021, 04:25:44 PM
It's a pretty lame video, but it does have some good shots of the internals of the engine and valvetrain. The saving grace is that at least you get to hear it run near the end....and it sounds crisp! I've never seen one of these engines, let alone heard one run. I'm not sure if it's the oval collectors or the heads (I'm guessing the heads), but it certainly has a different sound than any FE I've heard. Hopefully it won't be another 47 years till it runs again. ::)

  The ex M/T employee was Scott Dapron (rip) Scott was best known for being a crew member on the M/T Bonneville record runs with the '69 Mustangs. Scott and Fritz were the best of friends and the only reason the engine was built .

Heads. It does sound almost like a early model 392 Chrysler Hemi. It should, as the Ford FE and Pontiac versions (yes, M/T did both at the same time) were patterned as closely a possible to the early design 354-392 Hemis.

Very cool.  Thanks for sharing.

So close if I remember correctly the valve covers will interchange.

   I only saw it run one weekend at Lions with the hemi. It ran low 12's and broke something on the second or third run. The headers were FAR different and it had 9" M/T slicks back then. Mickey drove it that day and was not easy on it. Tire spin was a problem. It ran almost 120 which was BIG for the day. It never fit into an NHRA class as the head was never accepted in stock or super stock classes despite what the current fender lettering says.Lions at the time was AHRA sanctioned and "anything" had a class.

Im sure with todays tires and suspensions(Caltracs) high 10s low 11s should be possible

    Ricky,
      Mickey had serious intentions of going into the steel AND titanium rod business. In the Long Beach shop , the upstairs mezzanine had stacks of boxes of rods in MANY configurations , mostly "H" beam designs and "somewhat" similar to a Carrillo rod. I bought several sets from M/T after I discovered them up there. They featured "pinned" bearing caps the "prevent" spinning rod bearings ( common to aluminum rods) and all had allen cap screws as that was the best bolt available "at the time". The parting surfaces were also serrated ( saw tooth) like an aluminum rod was  back then. I still have a few from a small block Ford stroker I built in the'70s. A really odd 5.220 length.

If you look closely at the shot of the rods, you can see the serrated mating surfaces. I thought maybe it was the one "new" concession to reliability, but maybe I was wrong.

We had the same M/T rods in our 389 Pontiac and yes they are serated on the caps Doug.

I have some NOS Mickey Thompson aluminum FE rods, they use the Allen head bolts. A friend has an MT catalog that shows those steel rods amongst other cool stuff.
 That must be a big stroker. MT sold cast stroker cranks back then. The piston skirts wouldn't need that kind of clearance with a normal stroke.
