318 build #2 "cost minded" for the '74 Duster

2.94 gears can actually start to make up time as MPH vs RPM in the quarter.

That was my experience on the street with my poly 318 '66 Coronet racing against predominately gm 350 powered cars with the common 3.08 factory gear.
Not a lot of difference between 3.08 and 2.94, but I'd gain a little on the top end around 70-ish MPH.

That 2.94 was actually a pretty good street gear. Not as much of a dog off the line as 2.76, and that slight top end "walk" came in at just the right time.
My poly 318 was way torquey, and did great off the line. Easily made up for the difference in 2.94 vs 3.08.
If you were one of my victims and got jumped by a fender or almost a fender off the line, then kept even or maybe gained that fender back, but at 70, started getting walked you pretty much knew going on was a lost cause.
Any faster than 80-ish MPH on the roads I was on was asking for trouble, and most of the cars I raced were built street cars kinda in the same boat.

Surprising 350 guys with a 318 was a super bonus.
