Hey everyone
Well it's been quite the freaking trip with this car. I went from worn valve springs, to cracking all the valve seals, then I broke a bolt in the manifold, then some plug wires were switched, and there's still a few problems, but anyways, I finally ran the car after a WHOLE SEMESTER of not racing. This is a crime in my mind . Anyhoo, I was supposed to race Friday night, but the track is sooooo hilarious because they closed it and didn't update their web site, hilarious guys, hilarious. So I got to race Sunday during the day, because that was their little "I'll try and make it up to you" day, I guess. I was having problems shifting the car into second, I'm pretty sure the clutch is about to kick the bucket, but anyways I mustered this on my last run:


15.3@90.71 with a 2.211 60'

I'm excited because I'm EXTREMELY confident that I can hit 14's, no problem, for the following reasons:
-The oxygen sensor was PEGGED on 1.000 and above the whole run
-Had some knock; not enough timing down low, too much up high
-Bad 60', I've cut 2.0x's before the cam and intake, I should be able to get into the 2.0's no problem, I just haden't driven the car for a while
-That MPH is good enough to put someone into the 14's in and of itself, as soon as the fuel and spark curves are ironed out, it should be no problem at all

So basically I totally realize the value of prom burning. I'm pretty pumped, this is going to be a fun semester. The only thing that irks me is my FPR, but I'll post that in a different thread.

Thanks
Tony

 

Well you have seen my setup Tony. What makes you think I can beat that????

 

nice times considering the 60', you should be around the mid to high 14s with that MPH. And with some tuning, consistent mid 14s shouldnt be a problem. GOOD LUCK. I would have been able to get new times with my ACT 9.5" 2400 stall and probuilt tranny today but we got rained out.

 

Heads, I think with your car tuned well it'd be interesting. The only thing holding you back right now is your gears, open rear and maybe some stickier tires (your tires now are pretty nice though, actually). Add those and a torque convertor, and it would be all over for me .

Yeah, this semester should be fun!

 

Hey congrats. Prom tuning is the key. I bet your times will be limited until you get those headers on. Than 14's should be the norm for you. I can't wait to see what my LT1 cam combo runs.

 

I'm waiting patiently for the times too... I wanna see how it works out for you.

Yea Shifty and me will get to the track with some good prom tuning when the FREAKIN COLD GOES AWAY !! Ahhh its only been like 2 months of cold now and I already cant stand it.

 

I KNOW you can break into the 14's with your setup. Of all vehicles MY car did a 15.3@87.00 (you have no idea how well I had my car running that night) so with a little fix-me-up and that cowl induction hood you'll be all set!! Let me know when you're ready to put those headers on cuz' I wanna be there...

The thing is, I want either the prominator or the autoprom, I'm still not sure of the differences between the two but I do want one of those. I definately want to hit at least a 14.6 before I spray it.

Fun times

 

Does any one think its possible to get an l03 into the 13's with out nitros?

I was pretty confident it could be done until I read CHP's artical about their 87 carburerated z28 305. They did everything you could possibly do and only got the car into the 14's until they added nitros.

I'm talken everything. Heads, Cam, Intake, Full exuast, 3.73 posi and the thing barely managed 14's on a rebuilt motor.

 

pretty sure you cant get an L03 into the 13s but you could get a 305 TBI into the 13s with alot of work. Right now im running 14.791 with the mods in my sig minus the torque converter and new tranny, im sure id be able to get it in the 13s with a LT1 camshaft, edelbrock carb intake, and some world torquer SR heads or ported 081 TPI heads with 1.94/1.5 valves and a **** load of tuning. It could be done im sure, just take alot of work.

 

vj, can't remember who it is, but there was someone in the 13s with stock heads, cam and intake. he used to post on here a lot, but i haven't seen him in awhile. if i remember correctly, he'd done a lot of chip tuning and suspension work.

btw, when does it stop being an l03 and become a 305 tbi? i'm thinking the heads?

 

i think a L03 with an aftermarket intake would still be considered a L03, but if you have a new cam, i think it would now be a 305 TBI with L03 heads. New heads and it just becomes a 305 TBI. Thats my logic and im stickin to it.

 

that seems logical

 

To me an intake manifold is considered a bolt on. Anything short of touching the actual block or heads and cam is a bolt on and would still be an L03. This is my thinking atleast. My goal is to have the fastest stock block bolt on L03. This means stock head's, cam, pistons, crank, etc, but intake, headers, even rockers are a bolt on to me. If you only have bolt ons you can safetely still call it whatever the original engine code was. In this case, an L03.

 

hopefully i can get my L03 into the mid 14s before i get a 350. Im sure my 2400 stall, tranny, and edelbrock performer tbi intake will be good enough for at least 3 tenths.

 

An LO3 is an LO3 no matter how you slice and dice it. What defines an engine code is the block, not whats attached to it. As long as you keep an LO3 block, your still running an LO3 IMO. You just better include the "heavily modded" part...

what is the difference between the L03 and LB9 blocks? So, even if you put TPI on a L03 new heads, camshaft, intake, exhaust, etc. It is still a L03? That seems like cheating to me LOL.

 

Well that is kinda like putting SS or IROC stuff on your car. Is it an SS or IROC then? Even though it has the same exact GM pieces that go on the real thing? The blocks are the exact same but since it was not a TPI in the first place it is now instead a clone. I would say that it would be a TPI set-up that is identical to the GM produced one. That is what I would do if I made such a conversion.

 

I would just say, "Yeah, it's an LO3, I just fixed it..."
