What brand of opti-spark are you running, sounds like you have alot of
good perf. stuff on your motor. What about the block? anything done to it? how many miles on it. Ever do a leakdown test or compression test on
the motor? any results from those tests.I dont remember what you said about your exhaust system,but I am sure you are aware these motors like to breathe! ed

Those are awsome low end #'s. I am no expert, but I think you are lacking fuel. It just drops off like you have no more fuel?

Yes i definetly plan on getting it to the track asap, and i have CIA long tubes, K&N CAI, High flow CATS from CIA, hooker catback exaust. And I have a Delco Opti, ya i went all out and, i'm telling you i have been to hell and back litterally with this car and still can't get it right. I'm about to really give up. Plus the dyno is from when it had 100k bottom end the blue graph and the red is after the bottom end rebuild only about 3500 miles on it. Block was honed at the machine shop

wouldent' the dyno show good fuel pressure or the car would not run right, if the fuel pressure was a problem right. I don't have an aftermarket fuel pressure regulator on the car

Was the converter locked or no?

Looks to me like the torque converter just screwed up the dyno readings with the crap loads of torque down low and falling off so fast. Ignore the low end torque, with stalled autos its not going to be accurate. Didn't the dyno give a readout of the afr?

I just skimmed through some of that other thread and the power it made on the 100k mile engine seems about right to me for your setup, it had to be something that changed from then to now IMO, but track times would tell a better story.

that's true, but the tuner said that i was a little lower from the motor being a fresh rebuild. on either of the build it still way less than the 370 to 390 hp that lloyd said that it should make

How many miles on it? It should be back up to full power within a few hundred miles.

350rwhp isn't that far away from 370 when you consider all of the factors like how much power your torque converter is eating and the way that dyno reads. Without the afr its more of a guessing game though, if you can get it that should give you a better idea. The tune will make a huge difference also.

If you have 3500 on the bottom end you should be back to full power. There are way too many variables with just a few dyno runs to compare. It looks like the TC is doing something funky to the dyno. It also looks like you were still making power when they shut it down, it doesn't look like it has peaked yet.
