    The 390's rock. Please check out my cardomain site, particularly page 2, where I go into length about the tunnel-ram part of the build.

    I run them with stock jetting, and literally bolted them on and laid a 50' patch down my father-in-law's driveway ten minutes later. The roller-cam engine, with its quick throttle response, seems to be a good fit for the tunnel-ram -- this is an older 289 "street" tunnel ram -- and the 390's appear to be an ideal size for a small-block. It runs a little rich and idles a little quick to get a good scary lope out of the cam, but it runs nice.

    EDIT: They are Holleys, though. If I could do it again, I'd buy Edelbrock 1403's and save myself a couple hundred dollars in Excedrin.
