Re: Ray Allen versus Jack Werst '1970 SS/EA Showdown'

My friendship with Ralph grew steadily over the years because of a mutual respect.; and I was deeply saddened a couple of years ago by his passing. He became a true "best friend". As far as the Briggs Chevy is concerned, I believe they used a relatively mild cmashaft, by GK standards, that had been designed as a small block cam profile for 1.5 rockers. The 1.7 rockers on the Big Block, however, turned it into a very good combo. It was a 309/318 grind, can't remember the lobe center, but I think 110. I know the car was quite heavy but I don't believe they went through any deceptive measures to illegally **** weight around - that wasn't Ralph's or Tommy's style. At the time they were into cylinder wall finishes, ring combinations, etc. There was a time when they were into very smooth (polished) cylinders with chrome stainless .043 rings, moved higher on the piston, and low tension second and oil rings. At the time that was pretty innovative and it no doubt found its way into the Chevelle motor. They eventually went away from the smooth finish and more in to .043 dyke type top rings - still high on the piston. Hoffman Machine would fill in the original top ring groove, because back in those days they would use the TRW replacement pistons. They felt that Chrysler really wanted a car in their class to dethrone the Chevelle; and the car that, I believe, was built particular for that purpose, was the Fink Brothers car. I hope I have given you some info, but I will probably remember more later. Dave Colbert P.S. I am planning to try to reprint that GK catalog from 1972 because it has hundreds of pictures of cars from that era that were GK users (just about everyone back then) for every make and class except the top fuel cars. I think the folks on this site might be interested. |

Dave 'Bad Banana',
The big thing back then,,,,was the Sunnen CK-10 Power-Stroke Cylinder Hone,,,,,,,,,that unit could really get that fine finish,,,,and proper cross-hatch,,,,,, Every Top Machine Shop had to get one,,,,,,,,that was the #1 piece of machine shop engine rebuilding equipment for the performance shops during those times,,,, That CK-10,,,,,,,a beautiful piece of machinery... |

The man doing the honing......Honing is right up there with other very specialized skills......I honed many many sets of rods and worked my butt off to make them straight and round.... I worked in a shop that did a great deal of machine work for Ralph at T/K's The owner was named Bill Crowley at Crows Head Shop here in northern NJ.....If he honed your block you could be assured it was right and Ralph often called up after an engine that had just been dyno'ed with a fresh hone made more power than ever before..... By then the super smooth cylinder wall finishing idea was long gone..... Bill was fanatical about blocks and had a little technique for the final finish that seemed to always work..... He was also a super talented head machinist and long befoe there was a Serdi or similar type machine his VJ's were just about perfect.... He also was a very skilled head and manifold porter.....and did some intakes that were not topped for many years.... He went to Nascar country......along with many others in the engine business......

John Hoffman never had a Ck-10, he used a big ice tub and honed by hand and his stuff was fast.

When I worked with Ritchie Zul in the mid 70s he was still using the mirror finish cylinder walls on the Pro Stock motors he built for a few customers, I did all the block prep and boring but Nassau Hone did the honing.. My ears are still ringing from the dyno pulls. |

I used to let Ralph send my blocks, heads and manifold to Crow's; Got my crank work done at RC Automotivr in Alex., VA and then go up to T-K to assemble, dyno and tune the motor there before taking it home. In those days we only had stock blocks so we had them all checked for wall thickness, especially on the thrust side of the bore (at least .100) and hardness checked. Good (thick) but soft blocks may have gotten the chrome stainless rings and hard blocks the moly rings. I had a time convincing Ralph that I wanted to use cast cranks. Of course we needed to have them "magged " to find a good one; but they were lighter and while they made no more power on the dyno at a given rpm, I always felt the motor was able to accelerate through the rpms faster.- and hit the converter harder. |
