Vortec cam in an lo5?

[SouthBoston]

Can you run a vortec roller cam in a tbi 350? If so does it do any good?

You can but you need the plate that holds the lifters in place and maybe something else, I don't remember.

The Vortec cam is a roller cam so you will need a roller lifter set up. Either stock or aftermarket.

I'm not sure if the TBI motors are fully machined for a roller, but CompCams sell a roller retrofit cams/kit that you might look into. Not exactly sure what it entails, but they are made to run in flat tappet motors.

Would this cam work in my 92 5.7 lo5 with everything stock except for headers, ultimate tbi with spacer and open element air filter?

Most TBI blocks are roller ready, but some are not.

That one appears to be a little big to try and run without a tune.

Horns: how does this one look? http://www.compperformancegroupstor...roduct_Code=08-464-8&Category_Code=RLERCAMXFI

I wish Comp would list specs on their page so I didn't have to try and look it up.

Haha thanks in advance to anyone offering advice. This site has been a great place to expand my knowledge and help me tune up and bandage the old z71.
