You could go with an LT-1 cam which you can get on Ebay relatively cheap. As far as going with vortec heads, it would involve getting new intake manifold since the vortec heads has 8 intake bolts vice the regular 12 that is currently on your set up. You would also need to look into burning a new chip.

350 was an l98 engine with vortec heads. The car is running and am currently using 55## injectors and about 26-30 PSI on the fpr. Still need new exhaust pipe from cat to muffler, chip burned and 3.73 gears installed. The car runs strong but still looking to get a chip burned.

If mileage is a concern, leave in the LO3.

Sorry... I didn't mean that.
