swapping a 305 tpi setup onto a 350 requires a 350ci prom & 21lbs. injectors to replace the 305 prom and 19lbs. injectors.
Other than that I don't know that the specs are on the 350 tbi cam but it's anything like a carb cam then the thing will be a slug until you put something tpi suitable.

its like .385 gross intake lift 
but i cant remember the duration and LSA. just google it, but i think the lift should be enough to give you an idea of how horrid the LO5 cam is... heads are terrible too. If it is a roller cam motor its a little better since you'll be able to put an L98 or LT1 cam in there. You'll need a new knock sensor also. You can get one for like $40 from JimsPerformance. I'd also like to know if anyone had dealt with them. I was thinking about having them modify my harness to run the TPI and my 4L60E.
On the LO5 cam, I found some message board where someone posted up various cam specs. He lists the 93 LO5 as having a 350 int. lift, 384 exh. lift 178 194 dur @.050. He had a question mark next to the exhaust duration which i though was kinda odd too being so much different than the intake. But basically you get the idea, LO5 cam = CRAP!
