I have a 79 Formula W-code.
W code means 4 bbl 301 NA.
Mine also has the ST-10 and 3.08 rear.
Rebuilt the motor, added headers and 2.5" X-pipe dual exhaust,
it is Not a slug. It will smoke in 1st all day long, break loose in
2nd and even chirp 3rd. Poncho's aren't high-winders like the SBCs
but the low end is there and that's what pushes me back in the seat.
I like the 301. Sure, it doesn't have the torque of a 400, but as a combo
of weight, performance and gas mileage, plus the last true poncho motor,
i would keep a numbers-matching formula as such.
