We currently have a tired 184k mile 318 in a 68 B-Body with 2.76 gears and 275/60/15 tires out back. We drove 232 miles to the Nats and average 20 mpg driving. The 318 has a Weiand Action Plus/Summit Headers/Firecore50 wires/Mancini Racing Ignition setup/1406 Edelbrock/Summit Racing K6900 cam currently.
The 318 is getting slightly tired and leaks/burns oil.
We have a spare 79 360 minus heads/intake out in the garage that would need a rebuild but, I am thinking of keeping this on the budget side of things. That being said the 360 would have slightly off the line torque. My question being if I built the 360 I was thihking of using the above top end package off the 318 for the car.
A couple of changes I am thinking is we do have a TQ 800 cfm with an electric choke that has been rebuilt. Also, I am thinking of this cam for the 360 since we have a heavy car and 2.76 gears.

My goal is mpg here along with some peppy power and run 14.9s with the car? Just wondering what the opinion is here. Also, we can get a set of factory LA heads cheaper than the Magnums so we would use the 1.88/1.62 heads. What do you guys think? TIA.
