Mild Torque 318 suggestions wide open!

For your wife, it sounds like this will be easy and the idea of not going too high on CR or cam or HP sounds spot on the money. I'll pull back my suggestion on the 1.6 rockers... it won't do a thing for her.... it's just for you LOL

Find a good 600 cfm vacuum secondary carb... the old List 6619 Holley's did a great job and had good economy, but it may be hard to find one in good shape. And if you want a stock type intake, then you may be stuck with a spreadbore type anyway.
