Sure glad there are guys around to remind >me that performance is the least important measure of a car. > The point I was trying to make is that if I bought a 280Z, (300ZX now), or a Porsche or BMW, and I took all the emission control garbage off of it, or perhaps add a turbocharger or nitrous oxide injection, you could probably end up with a car that could accelerate just as fast as your 427 corvette. Your comparison between your 427 and the emission control-strangled new 280Z's and BMW's and Porsches is an unfair one because whenever an engine is designed to meet emissions standards, something must be compromised, and that something is usually POWER. Your 427 does not have these constraints. If you had to make your 427 corvette meet emission standards and gas mileage standards, your 427 wouldn't be any faster than today's Porshes, BMW's, etc. Dennis -- Call-Me: Dennis Gibbs, Univ. of Md.

Conversely, if you bought a Porsche for the price of a 427, it wouldn't
go too fast, either.
Just to set things stright, a 427 is a four hundred twenty seven
cubic inch engine, or seven liters even. All else being equal, the 427
is going to put out, just on the basis of its size. In addition, the Chevy
Rat has among to most sophisticated heads on any American V-8, the famous
canted-valve open chamber heads. Check out a 427 (or 396, 402, 454 etc)
with its valve covers off. Those pushrods are splayed for exactly one reason:
FLOW!
You know, there's something people don't mention a lot about cars
like the old Vette: solidity. Every control in the car feels solid, really
solid, and most require an incredible effort to operate. All in keeping with
the mystique, I guess.
