200 mph 67 Imperial!

["Rob P" <fristpenny@xxxxxxxxxxx>]

The horsepower probably isn't the biggest problem.  Tristan was talking 
about turbos.  Check this site out.  Never saw his dyno test/et though. He 
uses a carb, not the hot ticket for a turbo.

500-600 hp isn't crazy power for a big block these days.  The O/D trans 
might help, but I hear that the gear spacing is a little too wide.  O/D 
replaces 3rd, you flip the rods and 3rd becomes 1:1. I always wanted to do 
this to my 'cuda, but I never fix what isn't broken (& sometimes not even 
stuff that is)
Gear Vendors supposed to be gauaranteed to 1,000hp, but I have heard some 
sob stories about them & three times as many people who swear by them. 
Remember this is all possible if you spend the $$$$$$$$$$$.
Keep me posted
Rob
