    I had a 60 Buick Invicta with the 455. Boy that car had some oomph!

    Do numbers of these size equate to speed? I like going fast so I can defer tickets.

    In that case, I'd like to suggest ANY Corvette with the magic L-88 in the furnace room.
    I'd still like to find the real numbers for GM's LS6...

    My 2010 Camaro SS is rated at 426 from the factory (crank), after some exhaust/intake tweaks I pulled a 427 HP at the wheels on the dyno.

    I had no idea the 351 Clevelands put out that many ponies! I had a 351 Windsor, recognised as the 'weaker sister' of the two engines, but it was the toughest thing I ever owned. I commuted from the NY/Can. border to NYC & back several times for day jobs with ZERO oil pressure! It just kept ticking 'em off....

    Finally sold the van to some guy who put the engine in a wrecker....it might still be going today for all I know........

    My first car was a '72 Buick Electra with the 455. I had the Stage 1 heads, and that was the best "sleeper yacht" I ever had!!

    Sometimes I'd like to get that car back, and do some serious house cleaning - getting all the distracted drivers off the interstate.

    I have often thought about the 60 Buick Invicta. It was a boat and a half. White, that funny extended back window, and the squarish fins and shape. It was graceful and beautiful to look at.

    If I had it now, it would be fixed up and looking like new as I prowled the roads. It would probably take away from some of my time though.

    Well we sure can't be allowing any of THAT to happen!
    Your Spydering season is already too darn short for human consumption!
