Horsepower Loss With A Fresher Engine

[baredss]

i asked in another forum but no help , i swaped motors in my truck with a 1992 van 5.7 i dropped a lot of hp the only thing that differs per specs is the tbi the 1990 is #17090022 the 1992 is #17090061 , does anyone know if there is a cfm or injector size difference or computer communication problem anything will help thanks

What if you try swapping the TB from your '90 to the new motor?

I'd use the TB assy from the old engine, along with any sensors.

i had planned on that , i was really trying to put a method with my madness so i knew what actually made the difference for later reference & my own peice of mind , it's such a small peice anyways

 

thanks

a lot of times an engine will run stronger with higher mileage. Not 150,000 but like 10 or 20,000 my experience is that a broke in engine runs better than one with 2 miles. just my $.02

I sense some rivalry there!. ahh CSM does a good job though, I think they seperated from Trick My Truck so they wouldnt do that shit anymore. CMTs got some other posers painting bees and honey on the interiors now!

I think the van motors had lower HP and torque numbers than the trucks. The cams might be different, possibly other things.
