Rhoads lifters 360cid

Rhoads lifters are not so much a cruch for me but a cost issue....I already have them. This little eng. build is going to freak my wife out if I dump too much moola into this one.
Looks like this is just going to be a shade tree-er stab at performance.
This is a thought I hate, but one that will create a running engine and a semi-compliant wife person.
Looks like I can afford a cam, springs for extras.
I have an LD340 intake to use
Many other items will come from either a swap meet or pick and pull.
This is not my dream build.
A real old cuda would be the dream.
I'd be real happy w/ a good light duster.

Thanks.
