Now that i got yalls attention.....
Does anyone here know the specs on a 92 Chevy 350 TBI off of a Silverado would be? Or rough estimates.... Its stock HP and TQ numbers.

What HP and TQ numbers would it have if it had the TPI intake?

Base/ Plenum/ Runners and 19lb injectors?

Stock is 210hp & 300lb/ tq on a TBI 350(LO5)..... if you want to convert to TPI its gonna be a b****....& when you look into stock TPI set-up your going to see its limitations & then see how much parts are for it to make it run quicker(52mm TB, SLP runners, Hi-Flow base of some sort, then the wiring harness, sensors etc.) & realize how much it costs to convert to TPI your talking about $1300+ unless you get it all on ebay to build a high flowing Tune Port that produces 350hp+/-. I was going to do the swap but I'm on a High School going to college budget & can't afford it..... as for injectors 19 lb/hr is for 305 & 22 lb/hr is for 350.
