It would help a lot if you told us what your engine is, what year your truck is, all the other engine modifications you have, etc. etc.

My truck is a 90, 5.7 tbi bone stock! I plan on doing the ultimate tbi mods while shaping to the new intake. Future plans are 2500to stall if needed, definitely gonna build the 700r, Regear to 3.73 or 3.42. I'm running 3.08 now. I have a set of long tubed I plan to run a h-pipe into magnaflows with 2.5 or 3 pipe into turn downs before the axle. Last but not least get a chip burnt. I may go vortec heads before the thou.

Neither of those two cams are going to be good. Even with tuning your TBI engine is going to hate them. The Jeg's cam has way to big of duration for a stock stall and the Crane cam just doesn't have enough separation for the TBI to like it.

You might be ok with that Jeg's cam and a tune and 2500 stall, but you're still putting a HUGE cam in a stock of an engine. You're gonna want to do some head work and you'll need a lot more fuel with a cam like that.
