Welcome to the club! That is one bad ass 3rd gen man! Wow.
I myself have a Prostreet 90 Camaro that I show,but do not race!
Total opposite of yours. I would love to run it at the track more,but in the past I have and it gets pretty expensive when things start to break.:rofl:

Yeah, you are correct there. Mine's extremely reliable but it's light like a potato chip, that's the key. My GN was heavy at 3600 with me in it and was going 9.60's at the time. The engine was reliable with only a couple head gaskets letting go once in a while. Everything else on the car never faired too well with the power and weight. Control arm mounts bending and one almost coming through the floor boards, plenty of broken converters and transmissions, U-Joints, etc. My Camaro is only 2450lbs with me in it. Simple 468 stock GM block with a set of heavily ported old Dart 320 heads and a good size cam with about 730 lift. The engine was built to run on methanol with about 17:1 compression but I've always run it on gas. I like the fact that the car is maintenance free, just oil changes about every 50-60 runs, plugs about every 20-25 runs, put in gas and go. If I ran methanol I'd have to drain the tank and purge on gas and that's just too much maintenance. Lots of times I leave the Camaro in the trailer if I know I'm running the next week. To me that's fun and it's really consistent.
We are still trying to figure out why the car is not responding to timing changes. I ran the 8.98 at night, cool weather and a hooking track at only 34-degrees of timing. Plugs look clean with no metal flakes on the porcelain so it's not detonating. We've added as much as 4-degress of timing with no signs of detonating but the car still runs the same number. We've tried different jets and all it does is blacken the plugs but the car run the same numbers. I'm gonna try a friends carb that I know runs well just to see if it makes a difference. Eventually I'll figure it out or I'll dial it down and be happy with 9.2 brackets in the heat and 9.0's in the cool weather. That amount of swing in the weather tells me that something is not right in the tune. A little variation is normal but not 2-tenths. I'll figure it out.
Sorry for rambling!
