Question for DG Gilbert on the Tasca Super Boss....
« on: January 14, 2019, 04:48:10 pm »
   David ,
       I was looking at the Petersen Archives (1960 section) and ran across some later photos of the Super Boss I am guessing it is the same car as the Street Boss but I could be wrong. It is certainly a MUCH more race prepared car.  Some of the other pictures show the rear wheel off and you can see the Dana 60 rear , coil over shocks and Logghe traction bars. The caliper is in an odd location but is still a Kelsey Hayes 4 piston unit. It does look like the front wheels a spindle mount with no front brakes. There is also an interior shot where you can see into the back of the hood scoop ( open in the back only) and see the Hilborn injectors on the 494 Can Am engine. I never saw the car in this state and was curious to see if you could fill me ( us ) in on the car at that stage. Brent Hajek obviously didn't restore it to that stage of development if it is in fact the same car. Does you dad know any of the 1/4 mile performance numbers? Thanks in advance , I am assuming others would be interested in finding out more about this car.

    Thanks DSO17 , I am not smart enough to link pictures and it took a while to find them on the Petersen. Hopefully David will respond. That is a very interesting car.

Prototype rear wing. Btw, it appears the Dana rear end has been inverted, because the rear discs are on the bottom? OR because of mounting clearance issues with the coil overs? Never seen anything like that.
Current lifelong projects:
1969 Mustang Fastback/FOX chassis, 6 speed, 4 wheel discs, with a modern Can-Am 494 (Boss 429), Kaase headed, intake mounted with a 1425 cfm 'B' Autolite Inline carb, ala Trans-Am style…Whew!
 
Volvo 1800, being converted to Boss 302 power…coming soon!

     I believe, as the photo presents, the axle installation is standard, as I recall, the cover profile & fill plug of the Dana 60 is typically is to the passenger side of the ring gear, in the rear axle facing forward pinion applications. 

    One would want to be hesitant to invert such units (although sometimes witnessed in the front axle installations of 4 X 4 trucks) as then the forward acceleration loads would be applied to the so called 'coast' side verses the 'drive' side of the the ring & pinion, an inherently weaker relationship.      ;)

Yes, correct. Reason I asked, because of the caliper on the bottom. Btw, Smokey did used 'inverted' rear ends with good success on some of his NASCAR Chevelles and T/A Camaros.

     I would have to be of the belief, that the only reason to compromise such, were to reposition the pinion and drive line to accommodate another engineering endeavor within the chassis.      ???

    Inverting the diff in a drag race application is asking for gear breakage. The diff is not inverted in the pictures. Caliper placement is very likely due to suspension components. While not optimal for "normal " applications , this is not a "normal " car. there are MANY subtle changes in the photos when you study them closely. I could see it being a very low 9 second car back in the day and is why I began asking questions. I wish David would respond with some of his father's insight rather than "our" speculations.

Ed, what makes you say an early ‘69 body with deluxe interior?  Just curious.  I only noticed the ‘70 taillights.

Sorry guys I was on a self imposed suspension but Randy graciously cut me some slack and I'm back in good standing. The pics are the Strip Boss and ran high 10's and high 130 with street tires and the Hillborn injection. My dad says the Super Boss was a Logghe body with a cammer and was Healey's project as were all the Ford sponsored race cars. That was also the last Ford sponsored car until Ford, and Tasca, pulled out of racing. My father estimated high 9's for the 494 Can Am Strip Boss with slicks. I'll do my best to get him to address some of your observations of the rear suspension and brakes. As far as trim and lights my father says they updated the 69 parts to 70 as they became available.
