Looks like I may be searching for an 85-95 RPO LB4 TBI 4.3 that may have come in Caprice, Monte Carlo, El Camino, Parisienne or GP. Believe this will have the correct computer 1227747 .. now to see...

4.3L is a Chevrolet engine correct? ... this is what I need to cannibalize right? I see the 85 Electra came with Olds 4.3L diesel ... this would not have a distributor ... Im looking for an 85...

PS Thank you for sharing that with me! .... really like this forum ...

I tried to edit the computer number I boobed but edit didn't take when I pressed save, not sure why, happened before

Ok this becomes my recipe.

1. EVERYTHING includes items available when I pop the hood in a junkyard or do I have to get underneath the car? I do not need the intake manifold? How do I identify the...

Have some big ideas on conversions with bigger motors Im thinking about and possibly a nice little fairly simple conversion has dropped into my lap to get my feet wet with. I just purchased a 1978...

Probably best idea is to get both engines up and running on carbs that I know more about first. Both engines are customs that may need to be dabbled with before trying out converting induction...

Really Im just having trouble accepting a 302 Chev would turn 8000rpm in 1968 and wont turn 7500rpm in 2016. Early 302s had the smaller main crankshaft but later ones didnt and held up better at high...

Lost last portion of post ... didn't lose whole thing because of auto-save, a nice feature I haven't seen on other forums. Is there a hidden key or something you can hit to do that manually, I...

I know I use forums sometimes to collect my thoughts (guesses sometimes :) ) as well as gather and share information. Spent some time on Pontiaczone pondering what makes rpm increase exactly and came...

Think I need to read my book before I pester you guys with silly questions :) I was thinking why not simplify and use computer only for fuel control and not spark control. Not sure why it needs to...

Had to start my'90 z71 today, first time in a month or 2. Battery cranked very slow but started right up and seems to run perfectly instantly. Let it charge battery awhile and zoomed the throttle...

Not sure how quickly this will go ... was thinking the computer in the truck might drown the smaller displacement (350 low compression to 314 high compression) but it is supposed to be self...

Hey Scott, Yes I live in Pittsfield near Concord NH. So your 455 is a TPI setup not TBI right? Actually I think Pontiac had fuel injection in the late 50's ... not sure what kind of setup , surely...

ScottP was wondering how many injectors on your 455 Poncho and how does it run compared to a carb'd car? I know my 90 Z71 tbi seems like it stumbles if I do a quick to the mat stab ... something I...

Wow , more great info ... will have to hunt a Pontiac 301 distributor ... now I have an excuse to go grab the whole engine that has been sitting on a shelf at a local junkyard with the factory turbo...

I used to be an electronics tech and think of this as a bit of a challenge. I wish I had a diagram with computer inputs and outputs to start with. Just helps me collect my thoughts as I am used to...

Wow got some good info here, not sure I mentioned I would not be running an electronic transmission just a simple turbo 400, and the intake I have looks like it has 2 isolated sections with a...

New to fuel injection performance modifications and just trying to get my bearings really. Printed out the "TBI Conversion" article on homepage and was glad to have clear pictures and explanations of...
