i have a 283 torn down $50.00 or a 305tbi $200.00. my camaro has a 5 speed and with the 305 and 3.08's it gat 35mpg religously. i am currently working on a 78 malibu 200cid solid roller cam 4.3l crank, heads, and injection 2004r and 2.29 gears.
i want to take it across the country on trips the car has 48k original and i seriosly think 40mpg isnt out of reach.
