What motor to go with?

If you don't want to get too wild just refresh the 318 and throw some bolt ons at it. I am pretty suprised how well mine goes with bolt ons no converter and 3.23 gears. A converter would really be the icing on the cake for what i currently have i think.

I have a 73 318 with what i assume has at least 150k miles on it. stock heads and bottom end, 340 cam, ld4b with a 600 cfm edelbrock carb and headers. Pretty incredible difference over the stock garbage. Still no racecar by any means but goes pretty decent. would be good for you if you did not want to go too wild. If you want to go wilder by all means go for it.:cheers:
