Had to leave for a minute but back at it.    Well, spending?   the Holley 950 Commander Pro TBI unit  4 bl. Stand alone 700cfm with 4 65 lb. injectors  Part # 950-22s is about $1,700.00  (http://www.holley.com/950-22S.asp)   From what I'm learning, that should handle present and future fuel supply needs.   And can be tuned at home without continuing to burn chips.   then, I've been told I'm gonna need a better cam to make the whole thing run to its potential.  Probably a stall converter.   So far, those are the expenses I know I'm looking at.   I am first going to try getting this injector that I have unstuck and even getting another TBI unit if I have to.   They are pretty inexpensive, injectors and all.   Can't hurt to try.    But sometimes this winter I'll probably spring for the best goodies I can get.   Just want to make sure the money is spent in the right place.

Looking at mapquest, I am about 90 miles from Williamsport.   I checked out the site.   33 years of experience sounds good to me.   I could get it there.  Do you know him personally?
thanks

Capt Kaos, I was definitely considering the 4bl. FI rather than the carb. unit.   I am trying to keep the plus sides of the fuel injection.    I could "find" the bucks that Holley wants if I had to.  My kids will understand that they will just have to go out to the garage and look at the engine in the truck to see their Christmas present.

Wishr, I don't live in the area so I don't know the folks at the engine building business.I found them thru a web search.
 You want to have a powertrain system in your truck that runs like a bat out of heck and gets good gas mileage- we all want that, but as Capt Kaos has told you- the components of your build need to be planned out so they work together. You'll be a much happier camper that way. I think the pros at an engine shop are who you're looking for. Hope it all works out great for you. And not too expensive. Keep us posted-

The TBI unit can leak fuel around the injectors if one of the o-ring seals fails. It happens all the time after people swap out injectors.

Pull out your leaking injector and reinstall it with new o-rings then test it again with the wiring disconnected. If it still leaks fuel past the injector then it has a stuck injector. This isn't as common as the bad o-ring problem but does occur.
