[TPR] JB 351C build info

[Asa Jay Laughton]

I say.....
Four Blondes, four redheads, dressed in nothing more than a tight 
bikini, evenly spaced on each side of the engine, dribbling fuel in from 
graduated cylinders.  OH..... just the picture of that in my head 
SCREAMS horsepower.  That's gotta add at least 100 HP.

If you ask me -today- I'll probably say a balanced and tuned carb from a 
pro shop, like competition carbs.  Feed in the engine, trans, final gear 
ratios and tire sizes... and out pops a carburetor that seems to be born 
of the same DNA as the engine.

Ask me tomorrow, and I might multi-port Webers of the Fuel Injection 
variety.

But honestly, try the blondes and redheads first.   And get photos. :)
