a few tech questions


Hey guys

I am considering building a copo camaro to run in the FAST series, and I have a few questions regarding the rules. Sorry that there are so many, but I just want to make sure I understand them before I decide to build it or not.

First off, what do the camaro guys run as exhausts? Can we run dual mufflers instead of the factory transverse muffler? Also, I have been considering a chambered exhaust, but with better mufflers. (Something like these: http://www.classicchambered.com/classic/products.html) Do you guys think those would be better than a transverse muffler? Or better than dual drnomax ultraflow mufflers? (if those are allowed on a camaro, that is.)

Next up, what type of carb modifications are allowed? The rules say any internal modification. What is considered internal modifications? I remember reading somewhere that at least one guy (i think it was a mustang) has removed his venturis from his carb so that it flowed better, and that he still passed inspection. Wouldn't that be an external modification because it can be seen by looking at the carb?

Next up, a few engine questions. Would a Can Am aluminum block be allowed instead of an original ZL1 block? It doesn't have a raised deck height, nor a raised cam, and it was made by gm during that era, so I would think that it would be considered an oem replacement block. At least I could hope it would be. If it isn't legal, I see that you are now allowing aftermarket blocks if they are approved. Could you approve an aftermarket aluminum block? I don't trust the stock Zl1 block with the amount of power I plan on making, as I've heard it likes to (quote) "move around" at high rpms.

Last but not least, do you guys test for battery voltage up front? I was thinking about putting a correct appearing dummy battery up front and putting the real one in the trunk, but I see that the charging system must "be functional at all times", and I didn't know if you guys meant that the battery had to actually work up front.

I would, but I can't talk on the phone, as I have a speech disorder and I'm just to hard to understand over the phone. In person I'm a little more understandable, but over the phone, not so much. Even my family can't understand me over the phone.... So pretty much, I can only communicate in person or by writing or typing.

Re: a few tech questions


You can run true dual exhaust, the venturis would be internal, just the outside of the carb has to look stock, i`m unfamiliar with the Can Am aluminum block. If you e-mailed me some info on the block i`m sure it will be approved.. Although we are allowing aftermarket blocks so maybe your better off looking at a newer type block? See what`s out there and send the info to me (hemidave1@aol.com) from there we can approve it..

Actually the battery rule it a little outdated... Just make make sure the battery up front looks correct and there`s voltage at the cables, it can be gutted.

Re: a few tech questions


I just finished emailing you about it.

Oh, and about the using an aftermarket block instead of the Can Am block; I'd prefer to use the Can Am block over the aftermarket blocks as it's more "correct" than the aftermarket ones. At least I'd be using a vintage gm block, instead of a newer aftermarket one. That way I can still say it's based off an actual gm block.
