I'll challenge any of yous guys with 2 carbs to a race of your choice. My '50 3100 has a 235 high pressure '53 engine with a YF2100 carburetor on a stock intake/exhaust manifold.
How will I beat you? A T-5 transmission, a 4.64 to 1 limited slip rear end out of a 2001 Nissan Xterra (6 lug Chevy bolt pattern), and 30 1/2 tall skinny radials. That's how.
(I normally answer this multi-carb, soup up my truck question more tactfully, but I thought I'd change it up with a different strategy of bold directness to get my point across. No offence intended.)
