Seems that the new ACDelco O2 sensor fixed the knock count problem.

The last thing now is I really Really Really wish I had them rebuild my stock converter... The stall on this exchange / rebuild is just way too low... Belongs in a truck.

Time to swap it out? Have you chatted with the folks that did your trans about it??

Trucks typically have loose converters. That way you can take off with a large load and not bog the engine.

I'm just going to put up with it for now... I drives great but I swear the convertor is locked up at about 900 rpm. I did the motor / trans swap by myself in the driveway.... I'm still having re-occuring nightmares,,, and my hands/knuckles have just healed up.

More patience than I ..

The last transmission I did on my back, I think I was 18. I've had a lift since about 19 or 20.

As nice as fuel injection is . I still run carb. You cant beat it for off the line grunt and power.injection may get better milage, but who cares, were talking performance.you cant beat a carb dumping a butt load of fuel all at once to get a car moving! I have a 72 grand prix 463 cid 750 double pumper Holley . It leaves the line hard as hell. Run 12:40s all day.

You have got to be joking! My 2011 Infiniti M56S has been 12.2 @ 112 at 4,500 lbs race weight. The 338 CID V8 has not been touched save for intake, exhaust and tuning. The injection system is very capable as this one sprays fuel directly into the chamber at about 2,500 psi during the compression stroke.

You think a a processor that can execute over two million instructions per second reading from a TPS sensor, and injectors that atomize fuel precisely, can't do it better and faster than an accelerator pump?

Here hold my beer!

Fuel Injection Makes more Power... period.

It is true that carburetors have excellent throttle response. My injectors max out at 60% duty cycle so I can get all the fuel in before valve closes, even at 7000 rpm. I have no trouble matching the throttle response of a carburetor.

And I have a wide-band O2 sensor with closed loop compensation during acceleration so the fueling is always spot on. Can't do that with your carburetor.

Pretty sure any one of us could make our third gens faster than the for way less than 130k tho, lol!

But you will never have the luxury and electronics that car does. It still be a flexy squeaky rattling thirdgen fbody haha

I guess you're right, but our cars are still cooler

Speed isn't everything. If it is, there is always someone faster. Cars start to lose their fun to drive factor as it slowly gets converted over to pure straight line performance.

It's supposed to be about how it makes you feel when you drive.

The faster cars I've had stayed tore up a lot. I've enjoyed cruising in my L03 for a while but I'm working on a L98 to put in next year. Got bored i guess. Hope I don't regret it later.

QwkTrip

iTrader: (22)

I don't know how you can regret an L98. It's still docile as a bunny.

dmccain

iTrader: (2)

True. Just hope it's as trouble free as the lil fellow in there now.

fullsize fun

if you want a better convertor, pick one up from a mid 90s tolower 2000 S10 with a 4.3, highest stock convertor there is .

dmccain

iTrader: (2)

I agree. That's what I run. Gives me around 2400 stall.

Jazzyjeff87

Not optimistic.... You have to take advantage of critical amount of torque. Not high rpm lt1 or ls1 ...i seen a 383 with procharger and Afr heads tuned and tweaked put it right right in air facing sky. It was 9.09 at 138.he tuned the hell out of it and tpi smart.tpi scavenge effect like headers they are desinged to be Torque monsters. Keep gears low at 3.12 or 3.23 ..any higher puts you out of torque and horsepower peak. Unless t56 6 speed manual then 373 potential option depending on full application. Get back.... I'm tpi....conisore. lol

KyleF

3.42 Gear is an awesome gear for a TPI.

iTrader: (11)

It sure can have some of them, and the only thing in my 3rd gen that squeaks or rattles now is the passenger seat, I spent a lot of time with the 1/8" closed cell foam in the dash, vibration damper on all the flat sheet panels and mass loaded vinyl on the firewall and full floor. Still have more to do, but it is much better than it was before. If my rear didn't howl, it would be close to luxury car on the inside for sound.

Jazzyjeff87

OK they were not Ferrari tight....its cause they had the heavy third generation door. It depends on factory,some came great, yeah some little choppy. .some were tight as could be.the t-tops never helped keeping it perfectly straight. Subframes kept them tighter.

what's the rest of this 9 second 383 tpi combo?

-- Joe

Orr89RocZ

iTrader: (20)

9.09 at 138 is letting out way early and costing which means its well into the 8’s at very high mph

Might be possible but hard to believe without more data

Did you mean 9.90? I can buy that. I tuned 550 whp on low boost on a 383 tpi and it easily would make 9 sec power if it didnt throw belts. Alignment problem

KyleF

Unless he is bouncing off the rev limiter in high gear. 1/8th mile car running the 1/4?

I'm sorry, but I don't believe a factory TPI Casting (Base, Runners, and Plenum) are running 9's no matter how much porting and matching is done.

Now if by TPI we mean a TPI computer is controlling the system but everything else is changed, sure.

Take the Audi to a car show and nobody will look at it unless they need a bumper to tie their shoe on lol .....but everyone will take a quick look at a third gen .........

I go to car shows a few days a week.

The only thing they associate thirdgens with are trailer parks.

iTrader: (2)

Have to say mine gets a lot of attention at carshows. Does well. Some people like to see something other than 57 chevys, 68 Camaros, etc.

Orr89RocZ

iTrader: (20)

I dont do shows lol i go to race tracks

KyleF

I haven't seen a thirdgen show up this year at our cars and coffee. The last one had a Ferrari 430, no less than 10 new ZR1's, and even 3 different generation Ford GT's (GT40 from the 60's was one of them to be accurate). Too many Z06's to count... not one Thirdgen.

Wished I had left my 'Vette at home and taken mine.

The Trailer park thing is changing as those have all rotted away into oblivion after 30 years, but a clean IROC... it gets attention. I know

no new tires

Need to finish your build first buddy.

I like going to both. The builds are cooler at the car shows, more attention to detail. Fast cars at the track for sure, but most of them look like mine. Not show quality, just go quality.

I don’t get the trailer park thing either.. show up with a showroom IROC and you draw a bigger crowd than just about anything there.. had lots of people take pictures, videos.. it’s hard to go look at other cars because no one has seen one of these in showroom condition since the 80s and wants to talk about it. I’ve had people offer to trade me their classic cars that were restorations worth more than my IROC. I’ve had guys obsess over it saying they’ve looked at every cruise night hoping to see an IROC.. Some of the “old timers” with redundant 60s restorations don’t get it, but that’s fine.. Had a guy with a restored Chevelle come right up to me and tell me that my IROC was his favorite car at a cars and coffee..

The trailer park thing happened when people would buy trashed or beat third gens or IROCs and put a spoiler on top of a spoiler, have 3-different colored body panels, hood pins, Summit, Edelbrock, etc stickers covering the back window, interior ripped apart except seats, rusty American Racing wheels, etc..

The reason that happened is because third gens were very eye catching and such a big hit that as soon as the people that could afford them new trashed them, the leftovers went to people with no taste and gave them a bad name.. by the 90s there were few IROCs that weren’t heavily altered by bad taste..

People forgot how awesome they were in brand new condition..

I guess it could be somewhat regional/age group based. I have a Chevelle SS that is an older repaint from the 80s and is badly showing its age up close, but from 20'+ looks decent and has newer style 17" wheels, lowered ~1". It gets a lot more attention and comments at a gas station than my 33k mile iroc. However, I will say that when someone says something more than "nice car" it is someone who really loves third gens and ends up being a conversation rather than a 5 second exchange.

Whoa, this was a side track, sorry to the OP.

Jazzyjeff87

no it was ported everything cowl hood. .. Had it worked I didn't believe it til I seen in hit the bumper.. . It was fastest tpi car with power adder I've ever seen.... It was insane ... Twin ported runners.... Vortech supercharged ,it was insane. Nothing on YouTube can compete.on bumper for 60 ft..... 700 r4 built with Ford 9 inch. Don't believe me...dont change it was real and happened.dad and son built it. ...tuned by IDK.

So no proof this exists... and what is a "Twin Ported Runner"?
