Well went out to moroso just to have some fun at the track. And wanted to now what you guys think about my run. I have everything that is listed in my signiture, I am not tuned, i have a 305 throttle body, My posi is not locking up any more (open diff), and missed 4 gear, but got it in right away,n/a. Had alot of fun sow some chicks, nice weather. had fun

R/T - .190
60' - 2.24

1/4 - 14.81
mph - 94.39

 

Hopefully that run wasn’t on the juice….LOL

Not bad, but I think there is a lot left in it. I ran a 13.8@98mph with a 218*/226* deg cam, headers, exhaust, open element, and a performer RPM intake. This was also in a Monte Carlo that weights 300-400 lb. more than your F-body. Your 60 foot times weren’t great, you can knock a tenth or two off there. Every tenth in the 60’ is worth 2 tenth in the 1/4. Also your MPH is a bit low, have your replaced your intake? What kind of “chip” do you have? If you haven’t done any DIY tuning then I’m surprised it ran as good as it did.

Depending on your heads, and intake, I’ll go out on a limb and guess that you could run a 13.7@99ish with traction and an aggressive launch….which would probably crunch the T5.

 

Thanks for replying, i have the bottle but have not run it on my l98 yet. My intake is a torker 2 open plane , i have a chip from brian tbichips(mail order chip). my heads are i think 198, the stock heads that came on the l98 350 tuned port. The heads have been redun with comp springs,and flow benched 5 angle valve job. my rear end is not locking any more, it is a 9 bolt with 3.45 gears. My t5 is built to hold 550 hp, tires on the car now kumho 711 that are nice for the street but not on the track. I also missed 4th gear but got to get it in right away. i know i need lots of tuning and a couple of parts for the motor, i should run a little better. -Eric

 

A 350 should run stronger than that MPH, get the car on the dyno and tune it. And like BMonteSS said, 60' is crucial to ET.

 

Sounds like a cool little setup, That chip is holding you back big time, your turning the same mph as a stock iroc but with a much bigger cam, and much less restrictive intake setup. If you take a look at the „ come in for free tune“ thread you’ll see that XJ’s TBI.com chip was over 10% off and he only had a big throttle body and full exhaust. I also noticed you said you had the stock TB....probably with the stock injectors. Your running out of fuel way early, probably enough to hurt something if you’re not carefull. I highly suggest you start datalogging and looking for a 454 TB with 80 or 90 lb/hr injectors. Then of course you need to get you some burning equipment. You have 50-75 HP locked up in the tune of that beast.

 

And if you don't have it already, a better fuel pump. With that and the larger TBI unit your setup has some serious potential. Tuning is the key (EBL).

all that is going to be done in the future, My funds ran out on my paint and the motor swop. i have stock 350 caprice injectors, but yes i have the stock throttle body, i now it is holding me back. fuel pump is oem but new, so it is passing right now. Need to start learning and studying tunning. Thanks guys -Eric
