HEI ignition, Edlebrock performer intake and 4 bbl, and a air/fuel ratio guage for tuning.

Look for a NP-833 (MY6) out of a 81-87 truck. It's a direct bolt up (Minus the whole in the floor for the shifter). I got mine of eBay for less than $400 w/shifter!
With the 307 I certain wouldn't go as radicly low as my 2.76 rear, but the Overdrive is great!

I've actually broke 19 mpg with my old 350, and since I put the 383 I haven't gone on any road trips but my mileage around town and to work and back (20% city / 80% Hwy) my mileage is between 12 to 16 (Depending on how mant HEMIs I eat!). . .

Good Luck.
