just wondered if there was many out there and what mods have been done and maybe some hp figures and times? Thanks, please dont knock 350 tbi's here I know the pros and cons.

 

look around. many people have 350 cid and tbi

 

jprevost is running a 330hp gm vortec crate motor. so far he has gotten 102mph out of it and a tire spinning et of 13.8. he will be home soon with more tunign on teh engien and the chassis though, so stay tuned to see how it turns out

later

Well, may be 317hp on Desktop but join the club on what to do about fuel delivery above 230hp. There's several paths and they're all here for the reading.

 

see sig

 

Hey, why is it that only Grumpy and myself have actual 1/4 mile times with our 350+ci TBI motors and nobody else does?
Get with the program people!!! We need/want more people to have fun with their cars, do it legal, go to the strip and see what you can do.

 

LOL Jon, it's easy. I'd love to run at the track, but running with a 2.73 open rear will probably put me in the 16 range. Yuck.

Edit: Besides that, my rear end is starting to protest, and I am due for a new rear end soon.

 

15.501@87.xx. Street tires, 4160#.

 

My car has a 350 TBI and has ran a best of 15.041 at 91mph and that was clost to stock with 305 injectors now I need more fuel heads and headers and something besides 2.73 gears but it is posi:lala:

 

ouch id say a 350 should run faster than that

 

I do agree but you can't ignore that they were probably mis-matched cars. Too much power and not enough traction or just not a good platform for the 1/4 mile (like the gearing).
It's funny but if you look at some of the L98 guys posts and then at some of the LB9 with a few bolt on's it's sometimes too close to tell the difference. Seems like the T5 hardtop 305 TPI's had enough ***** to keep up with a 350 TPI auto t-top or convert.
Definatly learn to program your own eproms because there is still something wrong with having a 350 still in the 15's. We've got a basically stock 91 LO3 that's got headers, gears/posi, performer TBI intake, open elmnt and ultimate TBI mods that is going to see high 14's soon enough. A little tuning and I can see it being a stable high 14 second car. I do believe he (Randy) is getting a higher stall tc also and he's finally got some boxed LCA's and panhard bar.
Man I wish I could knock out all of Penn and bring Ohio next to NJ!!! Sucks being in school until June 14th

 

I have a 300HP crate motor with TBI, 5 Speed trans and 3.73 geared posi rear.
No ET yet, due to the fact that currently, the closest drag strip is two hours away, and I'm sure I'll scatter my T5 trans soon.
Can't afford a 130 mile tow bill, if it does.
I can tell you, however, that it's easily beaten a couple 97 and 98 Cobras on the street.

Well my set-up SUCKS I cross the finsh line at like 3200 rpms I'd prefer around 4500 tractions sucks for the most part 60' times like 2.4 and 2.6 arent all to sweet but my first time at the track I got a 2.092 and that was the good lane didnt get that lane agian
I need headers more fuel gears 2400 stall TC and finsh my heads then rebuild the trans after I blow it out:lala:

 

that it.... no more??

 

i got a bored out 305...works for me. i beat my friends 96 t/a t-top...lt1. any1 know what those run?

 

keep it comein, i want to know mods others have done so I know what to do to mine.

 

dude, ditch that Stock TB and get a 454 TBI. And get the Performer RPM intake. Also The 1 5/8" headers are holing you back some. Pull the heads when you change the intake and Port match them to the intake and maybe a little pocket port too. You prolly know someone who can do that stuff easy. The 2.5" y pipe you got prolly aint helping much either. Get that chip tuned up and you'll prolly be in the 14's easy.

Oh, dont' forget to get some good suspension parts too. LCA, and a panhard rod would help a lot.

I vote for putting on a Victor Jr. or 7547 Holley.
