What is the biggest cam I can go with

So if I decide to stay with my D3 heads that I have done mild port work new valves and stock 22cc pistons and I go with the victor2 or rpm intake what is the biggest cam I can go with so I can race it occationally at the track and have still a nice street cruiser, and what kind of HP can I expect, also I will have 3.73 rear end c6 trans posi not sure on tires yet

What is it going in? Car or truck, and approximate weight. What size engine? Have the guides been milled down to allow extra lift on the valves? Do you have springs, and what style of cam do you want to use, hyd flat, solid flat, roller, and do you have adjustable valve train?

Its going in a frod f150 78 wanting Hyd flt cam 460 engine mild port work on the heads...

I would not go any bigger than this...... You'll need to put valve springs on it with this cam

I ran a lunati bracket master II in a similar combo with good street maners and got the old f100 13.0's. I tryed other cams all the way to comp 292 but the little lunati was the best all around. I think it was around a .515 .545 lift. No valve clearence problems.
