Figured id toss up a post about my latest attempt at finding a few more hp.....put the car on my friends dynojet for the week, Precision Dyno in Cranston, RI. Baseline test showed 553rwhp at that point i put some fuel in it and a hair more timing which netted, 560, then after a few more shots i wound up at 568rwhp......graph below

from there i wanted to check cylinder balance so i put a WB02 in each header tube did 4 at a time.......

at the end of the test, it turns out paying the extra coin for flow matched injectors is worth it, as well as taking time on the cam and airflow in the motor, even with the single plane intake with runner length differences i saw no more than .24:1 AFR difference from one cylinder to the next i got them to within about .2 it made no noticeable difference.........
all in all i think it went quite well I picked up 15rwhp and 13ft/lbs peak but about 18ftlbs up in the high rpm range....through 29" slicks, an unlocked 5200 stall th350 and 4.56's in a dana 60 I think those are awesome numbers for a car that i had already spent time tuning before and was already running great.....it ran 9.77@138.xx going easy on the launch with the old tune....i think its got some impressive numbers in it dialed in especially later this year in cooler weather....

Those are great gains...esp for just TIME invested in tuning.

That's some impressive #'s, even more impressive threw a stalled auto.

I've owned and modded my LT1 since 99 but only recently got back into the message boards(mainly this awesome one), and had no idea these numbers were capable. Crazy stuff!!! Wish I could make the shootout to see and hear it in person!

Those numbers just show what an LT car can do......
