SBC TBI upgrade 4 sale, Edelbrock multi-point - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**crossy** · 07-31-2003, 12:15 PM

The following write up is straight off of the www.Edelbrock.com website. there is also a picture there if you go to AUTOMOTIVE PARTS then MULTIPOINT FUEL INJECTION . My used kit is part number 3502 so it will fit any 87-95 TBI equipped small block because it already was the wiring piggyback in it . The Kit was missing quite a few fittings & hose when I got it but I went through the LIST OF PARTS that is with the original papperwork and I got eveything that was listed . all the fittings now are new EARLS brand with new PUSH LOCK hose. The kit requires that you modify your existing TBI unit but that is already done to my kit so you can keep yours in tact. the manifold is a little dirty as it was used 2 years and lived up to it's claims on a friends 95 Tahoe. I think Edelbrock could warn you a little better of other things needed but Just so there are no surprises to you I'll tell you you will have to get a custom chip ($50-100)and a high pressure fuel pump ( lots of options here , edelbrock makes kits) $?) . (unless it's for a 95 Tahoe/Yukon where you don't need one.) This will go to Ebay shortly but thought I would advertise here for 2 weeeks or so. $695 plus shipping. thats less than half price for whats here . I have paypal (ADD 3%) or accept postal money orders. DAVE

Performer Multi-Point EFI System
For 5.7L Chevy/GMCs Originally Equipped with Throttle Body Injection

Performer Multi-Point EFI Systems offer performance and improved fuel economy. All Edelbrock EFI systems use injectors that are angled towards the cylinder head port for superior fuel dispersion and better throttle response than other brands. These kits include everything shown on intro page. Fuel pump kits are sold separately to complete your installation (except 1995 Tahoe/Yukon). Important note: Calibrated only for use with stock compression, stock cam and heads or Edelbrock cam #3702 and heads #60859. See dyno test.

For 1987-92 ....#3502

For 1993-95 (includes computer piggyback adapter**) ....#3501
Installation Notes: Recommended intake gasket GM #10159409. Overall height (manifold & air valve): 1-5/16" taller than stock, same angle as stock. 1995 Tahoe/Yukon uses stock fuel pump.

** Price for these units will be slightly higher due to the added piggyback adapter.

Ok, I you got me wondering...
Does it have a TBI with it, or do you have to get a 87-95 TBI?
Does it have the ECM, or do you have to find/get one?

Or, is it this, with nothing extra?

**crossy** · 07-31-2003, 03:43 PM

If you are asking about retrofit? than I would assume you need to start with 87-91 (in our body style) Wiring set up that has ECM.
Mine is that exact picture , thank you, but does include an already modified TBI unit which is just air regulator now. MIne also has the correct EGR valve already in it .

For anyone else that might think about a retrofit to older rig I do have a set of factory 87 manifolds that have the O2 sensor bung in them. I also have shorty headers , alumacoated, with anti reversion cones in them ( old, but good ,technology). I am not 100% sure the headers fit though. offered only to buyer of injection.
That conversion can't be out of touch for mortals because there is a guy on the 67-72 board that has done all of his toys into TBI units.
As a matter of fact i was supposed to tell him if i wanted to sell this set up. Damn who was that ?????? or was that 75chalet???

Well, I already have a stand alone EFI harness, I just lacked the Throttle body. I can come up with an ECM also. No injectors right? Just trying to think through what I need if I got it to get it up and running.

**crossy** · 07-31-2003, 05:33 PM

It has the injectors I think they are Lucas (they prolly suck

) or Bosch. I also forgot to mention that MY TBI unit already has the IAC, and TPS on it . WHAT A DEAL!

*1FaastC10* · 07-31-2003, 08:33 PM

Dave, any idea what shipping would be to 46517? i've been thinking of buying the kit for my 91.

**crossy** · 07-31-2003, 09:02 PM

I have a nice heavy weight box set aside for this ,and properly boxed and insured for $700, this would be $20 UPS . I know Fedex is cheaper but there are no fedex depots near me.
Incidentally Captkaos , who has been PM me, has first stab at it and it would be $22 to Birmingham, Al. thanx for the interest. DAVE

**crossy** · 08-04-2003, 03:34 AM

I also just found out that PAINLESS makes a stand alone wiring kit for a TBI conversion for $265 ,so then all that would be needed is an ECM, used ones go for $25-35 on Ebay. DAVE

**Captkaos** · 08-06-2003, 01:41 PM

I am going to have to remove myself from the top slot.

*1FaastC10* · 08-07-2003, 09:52 AM
