I'd like to know who it was that did not remember me from an engine dyno session?
The 2 guys I use to seal my engines are Johnny Pruitt and Darrel Gabriel & every engine at either place over the last 5 years has been dyno'd.
Even though the on the head cam doctor does not reference lobe centerlines, it is pretty hard to change all of those numbers around without grinding some of the cam away and reducing the reference lobe base OD. I guess you could grind some off the front and back without reducing the base circle but the changes in either retard or advance would be picked up by referencing 1/2 on the duration numbers. Assymetrical lobe would probably fool that on the cam doctor but I am not sure that could be done and stay within reference #'s on the Adcole check.
That is the reason I was asking ???

I would also like to know who in MN did not remember me? Only folks I know from up there are Gene Pearson, Jason Line, Jerry Hemmingson, Warren Johnson and I think Todd Tesar was originally from MN. Myron Cottrell from TPIS, was a co-author on an article that Alan Lockheed did for Dave Emanuel did for Super Chevy magazine back in about 1982. Myron was a co-contibutor to the article and designed a manifold for EFI similar to the SmokeyRam I used on the 406 referenced in the article, my engine N/A was around 600hp and his 406 EFI engine was about 500 on pump gas. Bill Jones on here did the Heads and Intake manifold, I did the bottom end, Harold Brooksire did the camshaft for me and it was modeled on "The Engine Analyzer" software package by Alan Lockheed. I was told the cam would not work but it was one of those things where all of the parts were designed around the deal.The headers were done up in MN by "Headers by ED", at $3500 back in the day that was a ton but they were special for a Corvette with A/C. I still have the headers as a matter of fact...Dyno results from Keith Dorton at Automotive Specialists confirmed the results the CPU program kicked out. Might be none of these guys remember any of it, but I do because I paid for all of it out of my own pockets and that project from beginning to end cost about $38K from start to finish and I didn't get a penny for any of it. I did sell the engine to a street racer to fund the down payment on my first Superflow Chassis DYno.
Tshirt,
I am sure Dixie Performance, won't mind you talking up their crate engines and your carburetors, heck it might help out his crate business if he has only done 1 this past year. If he has only done a couple engines it would be difficult to determine what parts are there and how good they are compared to a baseline of the different series of parts that have come along in the last 10 years. Just so you know, there has been 3 different intake manifold versions, 4 different cylinder head versions, 3 changes in the timing chains and gears, 2 changes in the oil pans, 2 changes in the oil pump P/U, 2 versions of the crank & 3 versions of the PM rods.
The cylinder heads alone have had a variance of +/- 31CFM @ 25". If you can utilize 100% of this in your engine build that alone would be 30+ HP. This means the best set of heads you can find is probably 15-20HP better than an good set of heads and 20-30HP better than an average set of heads. Now if you match the right intake to those heads you will pick-up another 10-15HP if the final result of that is say 40HP and another 10-15HP you pick up by knowing what surface finish the rings like then you have an engine that is 40-50HP better than the next guy not working those advantages. Just because it is 50HP better does not mean it is illegal especially when it has gone thru National tech inspection dozens of times.
I am a true one man shop, no helpers or part-timers and I work 12-16 hours 5-6 days a week just to keep up. All of my engines that run in Fastrak or NeSmith have to be certified by another engine builder so not only is my reputation on the line but their reputation also.
why are you talking about Dixie Performance ?? I knew that man 30 years ago , he moved away ,, try again ,, I know where he is , he would laugh someone like you out of his shop ,, he's an expert ,, on engine building ,, not spreading BS ,, you might try that sometime yourself
and yes ,, i'm sure its quite hard for you to imagine ,, other people do know about the changes in those crate motors
