IMO, 600 hp. will get a lot of attention when even more people become aware of the fact that they exist,IMO.

I think the cars will get attention, but I'm not sure who will be the most attentive: the collectors or the parts guy! Not being negative, but from my limited experience with our late models and those of some friends, I don't see how the tranny or the rear even stand a chance! Tranny problems are frequent, and the little 10 bolts are weak enough even without further weakening it with a set of gears. I've seen cars with only !free mods be hard on parts, so I can't even begin to fathom what the phase IIs or phase IIIs will break! 600hp...it's not WHAT will break, but WHEN!

Regarding warranty on the '69 COPO cars, we had no problems at all. Right from the begining I had ring sealing issues and the engine got re-ringed under warranty.

Keith:

You are one of the few who I have talked to that had any luck with warranties on these cars when new...maybe you got better treatment in Canada? Or maybe part of it was that the warranty problems I know of are associated with Yenko cars, and the dealers weren't really sure if Yenko or Chevrolet was doing the 427 cars. Our car and another Francis Chevrolet car both sat for a while trying to get cylinder head problems fixed.

Those pumpkins are going to blow like they have a stick of dynamite in them. Their only salvation will be the fact that the typical owner of these cars is far less likely to "abuse" them than the typical Camaro owner.
From what I hear the trans is pretty tough.

They sell a girdle for the 10 bolts, which seems kind of like a band-aid to me. From what I've heard, most of the fairly serious guys get a Moser 12-bolt and be done with it. All I know for sure is that the 10-bolts in the Camaros (mine included) seem to be hard on bearings.

As for the T-56 being "tough", I don't know...my SS is on it's 3rd gear set, and I know of a couple of other manual cars here in the "woods" that have had problems. But, I've also seen some power adder cars run them with no trouble, so who knows. And, the new 500hp Viper is using it, so someone has some confidence in it! I'm not up on the auto cars, but I hope the 4L60E is tougher than the 4L80E that I had in my truck...2 rebuilds in just over a year. A manual tranny soon followed!
