NCRS Standards

[Joe C.]

All:

In the spirit of this organization, whenever anyone restores their Corvette, then they should endeavor to keep it as close to "factory" as possible. The camshaft is the "heart and soul" of the engine. Any changes to it will drametically affect engine performance, and hence, the characteristics of the vehicle in question.. We should not endorse any changes here, just as we do not endorse any changes to paint systems.

the CAM and the COMPRESSION

For some reason, some of the people here seem to not mind castrating the operating characteristics of the original engines. Altered internals of an engine not to original specification are in the same category as BC/CC paint. Period!

[Warren F.]

originality versus practicality

That line of thinking might be what all of us strive for ultiimately, but what about all of the members here who purchased cars used, and have engines that have been bored and rebuilt, originality is lost there forever.

Re: NCRS Standards

if i had a older corvette that was all orignal and was not chasing NCRS points i would replace the orignal engine with a GM crate engine to make sure nothing happens to the orignal and then you can drive the hell out of the car without fearing a big engine problem that could ruin the value of the car.

How About Clutch Systems?...

Surely replacing that ole diaphragm clutch with a Centerforce aftermarket clutch to improve yer overcenter problem would be O-U-T, out. It would be an outrageous un-sanctioned modification!

So, Joe...I guess you'll just have to strap a block of wood under yer clutch pedal if you want to continue doing those racing shifts and driving yer Corvette like GM apparently never intended. (Otherwise, the engineers would have provided a clutch that functioned properly under those conditions.)

You really should try some of that Fiber One...works miracles for me when I start getting a little cranky.

Re: NCRS Standards

Clem,

You have the best advice of all. I've often thought about doing that exact same thing to my 63 so I wouldn't have to worry about loosing the original. Just park it in the corner of the garage, fill it to the top with oil and enjoy the car with a clone motor.

Sooner or later ..............

it will come back to you that these cars are more fun driving than sitting next to it in a lawn chair at a car show. Thirty years ago, restored Model A's and early Ford V-8's were hot items. Now Model A's are worthless and the early Ford V-8's have more value in street rod form. I have no problem with some Corvettes being updated or modified to make them more roadworthy. They shouldn't all be maintained museum quality when only a handful warrant such care to preserve the history of the marque. My opinion. Jim Weeks Member #2978

Re: How About Clutch Systems?...

I always get a chuckle out of this sort of stuff. What it really boils down to is that these cars are never going to be as original as the day they roled off the line. After that, you can split hairs over everything. What about cast iron rings vs chromoly rings. Few would put cast iron back into an original engine. Can you tell if a person used cast iron rings? I supose if it smokes and runs crappy after 30,000 miles. Unless it is an obvious cam change, it would be impossible to tell. Also....if you rebuild your engine and put an original grind cam in it...it is not the original cam, it is a reproduction cam. I should go to St. Louis and start bottling reproduction air and selling it in the driveline for tire air. Can someone tell me what the difference in point deduction would be for reproduction vs regular air?

What is the point in putting a cam in an engine that can't be driven on todays gasoline without detuning it? Maybe the engine runs but it doesn't run the way it should. Do we subtract points for unleaded gas? What's the point diffence there?

Just having fun:) Terry

Re: NCRS Standards

If you build these engines right (read better connnecting rods), don't seriously overev them or run them out of oil, they are essentially indestructible.

Re: My Opinion

ANYBODY who is willing to put THEIR hard earned bucks into a thirty, fourty and even fifty year old driver or trailer queen, deserves a metal regardless the make!

Those people who poo poo ANYONE who exhibits the passion of owning one of these money pits should keep their collective and selective opinions to themselves and think of the overall good of this particular automotive sport.

There are contributors to this board who own those top flight cars who graciously (and patiently) share they're wealth of knowledge with us "Driver Types" without hesitation. To those folks, my on-going gratitude.

My top flight goal will be to see how far I can skip from one "Yes Maam" to the next without touching down

Re: NCRS Standards

Duke,

I still have a set of lightly used Carrillo 5.7" small journal rods (somewhere) so the bottom end shouldn't be a problem. Deck plate hone the cyl's to .030 and then a little cyl head work, the 097 cam and I'll be set.

Wonder if Crane makes a blueprint of that 097? The 097's that came out of GM the last decade or two before they were discontinued were terrible.

[Chuck S.]

Aw...Chuckster...

I hate it when you put that soap box down and climb up on it...you get all serious and overwrought, talkin' about them hard earned bucks and everthing. Is it too late to install an LT-1 cam and do a little port polishing on that old 327/300?! It'll make that old granny car a real D..D..dRRR...DRIII...well, you get the point. It sounds so good, I'm thinking about eschewing originality and putting one in mine.

Re: My Opinion

I think the most under appreciated car is the unrestored or mostly original car that is in nice condition. Unfortunately, they are rarely pretty and shinny any more. Terry

[Mike McKown]

My answer to that would be

that Chevrolet released oversized pistons and undersized bearings. They did NOT release low compression pistons for ANY SHP applications, nor did they release for service (while this engine was in production) any cam other than what was in the engine at time of production for SHP applications.

I've not understood the thinking behind some of the NCRS judging rules. They seem to be somewhat hypocritical.

If a C-2 Corvette was entered in a NHRA drag event that had the modifications some of you suggest, it would be illegal and tossed out the gate. Yet it is okay for NCRS judging and then you turn around and zap somebody for having a decent reproduction of a block deck and restamped numbers that is a decent replica. Or you get them for having the wrong head marking on a bolt. BS. Make the rules consistent with originality. All of them.
