Saw the vintage Dymo labels saying "Never exceed 7,000 RPM" and I had to chuckle, because by the time you get there, it's gotta be feeling like a NASA Saturn V rocket launch!

the strangest thing for me is that I really don't like yellow cars - but the combination of parts and the potential to scare the s#$t out of myself with it just won me over. And, yes, the sound from those pipes is unreal - sonically, I'd put it up against a Ferrari V12 any day, total big-block symphony
anybody have any insight on the tach design? I am used to 5700 RPM yellow line and 6500 red line in hi-perf Chevrolets. This thing doesn't yellow until 6200 or so...

I had to take my clock up to the shop to have the guts changed, so I took the opportunity to check this thing out in a bit more detail.
This car is truly amazing!! You couldn't ask for a more authentic period correct day two racer. The paint has this really cool patina to it, some very subtle pin striping. There are so many tiny little details like the warning stickers on the gas cap door and tach. Also there is the data plate on the shift plate, and a sticker on the console about engine damage if 101 octane isn't used.
Somebody went through a ton of work to make this car a real deal streetable racer.
Really neat car!!
I would have asked to take it for a spin, but we got a bunch of snow Saturday morning.

Had some fuel delivery issues which were solved by an electric pump and a new sending unit (tank stinker removed intact 
But I think there is more power to be had. A very experienced big-block builder has advised me that until I remove those side-pipes the power will be "below expectations". The exhaust pulses are completely thrown off by the side-pipes according to him. He had a '69 camaro that absolutely came alive when switched from hooker side exhausts to a traditional undercar system.
My problem is this: these are factory GM recommended exhaust pipes for the L88 road race cars. If you were a racer buying a ZL1, L88 or LS7 no less than Zora-Arkus Duntov wanted you to use these pipes. Every L88 racer (in fact nearly every Corvette race car) I have ever seen had side pipes, as did the 427 Cobra. I would think the L88 race cars were performing at the top of their game given their wins at Sebring, Watkins Glen etc. back-in-the-day. What am I missing...?
extra tidbit - the original intent of this car was for Gymkhana and autocross events - an early experimental roller cam set-up is installed that enhances low-end torque and horsepower....I had no idea roller cams were even available in the early 70s, but this thing has one.
