I'm GLAD you guys/gals know what your talking about!!! Where as I thought I knew enough about engines, I now belive I know enough to get myself in trouble! Now on to my question,

'89 350 TBI (in a siverado) all stock besides a beautiful set of headmans (I still have a few scars to prove I put them in...)
eventual I'm going to yank the engine and repalce it with a crate motor, but until the budget allows I'm sticking with the stock motor/heads/tbi/etc.
What do you guys/gals recomend for a good streetable...inexpensive Cam? Lift and duration? I was looking at the Thumper and Magna Thumper but wow! are they expensive for what I want.
For now I want the "chop" of a strong cam, while I invest in fixing the gremlins in the rest of the truck.

The engine came stock with rollers and I would like to keep the OEM ones (new)
