Need to sale this for a carb, used for 2 months before engine swap. Willing to trade for a 650-700 cfm carb.

 

First-design or Second-design injectors? Photos? Payment method?


Don't get me wrong, I bought one of those a year or two ago; and have yet to actually install the thing. I'm just suggesting that more info would make for a better post.

The one I bought has the second-design (better) injectors, but a cooked harness. I've got about $140 in it--$90 for the TBI unit, plus another $50-ish in the replacement harness and pigtails. I hope it works.

 

It is the newest Holley with the mini delphi injectors 65 pph at 12 psi and 85pph at 21psi. It is plug and play for 87 -89 trucks and vans. 350ci engines. Through you could use it for smaller engines at higher compression and higher psi or mildly upgraded 350's. I was told by Holley not to run them over 21-25psi. They are not designed, as a low impedance, to flow higher than 85psi. The injector connections do have to be spliced in. THIS TBI WAS BOUGHT BRAND NEW. USED BY MY 305 FOR 2 MONTHS. THAT IS ALL. Will include a higher pressure spring for regulator. I am asking $500.

 

 

Add fifteen dollars for shipping, and the new owner needs to buy a fresh base gasket ($26) and you're within spitting distance of a new one fresh from Summit with a new warranty.

[Edit] Looks like you have a TBI-to-4-barrel adapter--is that included? If the new owner uses it on a 4-barrel manifold, I don't think he'd need the expensive Holley base gasket.[/Edit]

 

It is the newest Throttle Body yes. Asking $500 or best offer. This thing cost me $600.

 

I'll include the adapter.
