63R1025
Serial number 1025, Sherwood Egberts personal car, production & development for STP on the R3 and used for advertising and TV Adds & Mr. ED. Featured in Hotrod & Motor Trend "STUDE HOTTEST R3" belongs to Ron Crall. The car was purchased by Vince Granatelli after the closing of Studebaker and was used for drag racing across Southern California
The head work is incredible to say the least. The cam is a standard R3 276 deg, with dual valve springs. Carb is a reworked carter AFB 3507S. The engine is 299 cubic inch with Forge(d) True pistons, Rods have had extensive rework and polishing, the cranks oil passages are reworked and is also polished, the oil returns have been deburred, enlarged and polished.
During the time that Vince Granatelli Jr owned the car it was used for Drag racing in the LA area. Records of the races are unknown, however there is evidence of a tire fire on the left rear fender.
.....the clearance between the steering arm and crank pulley, The
R1, with fresh mounts has almost 5/8 inch, the R2 and R3 with 10 year old mounts have just under a 1/2 inch.
My older brothers R3 with reworked frame mounts, standard ratio crank pulley and new/fresh mounts has 1/4 inch, as they age the settle leaving about 1/8 clearance. His engine has to be raised to install/remove belts, and yes there are rub marks or groves if you will on the steering arm. His front frame mounts were cut and re-welded to add additional clearance for the carburetor enclosure by Granatelli for the prototype R3 engine.
I have a set of R3 front rubber motor mounts here, well Stephen grabbed them actually to help eliminate some of his hood rubbing problems on his R1, they are about 5/16 of an inch shorter. I experienced steering arm rubbing when I used them on my Avanti with the carburetor enclosure, so I raised the body as the original R3 cars did to give the additional clearance. I no longer rub the steering arm, can change belts and have sufficient hood clearence.
I have no idea where the rubber R3 mounts came from. They arn't in the parts book,so I am guessing they are from the reproduction vendors. The factory R3 cars raised the front of the body for the clearence and you can't use the short mounts with the high output pulleys either.

Originally Egberts Avanti, forwarded to STP for development of the R3 engines. When Studebaker closed down USA operations the car was sold to Vince Granatelli Jr. Ron and I bought the car in 1970 with 34,000 miles on it. The engine had been dynoed during development at 435 hp. The head work is incredible to say the least. The cam is a standard R3 276 deg, with dual valve springs. Carb is a reworked carter AFB 3507S. The engine is 299 cubic inch with Forge(d) True pistons, Rods have had extensive rework and polishing, the cranks oil passages are reworked and is also polished, the oil returns have been deburred, enlarged and polished. The Paxton supercharger had been reworked to devolope 9 to 10 pounds of boost. The engine has a R3 pressure box and R3 exhaust headers. The engine has a standard oil pump and R2 pan. The entire engine was painted black with the exception of the headers painted white, intake manifold painted aluminum, upper pressure box painted wrinkle black and lower box natural. This car was on the cover of Hot Rod magizine with several pictures of the engine and engine compartment. The car was used regularly by the press for test drives and some TV advertisment as well.
