biggest problem I see is no converter to get that thing moving.
With 4.10 gears his 2500 converter should be fine. The 1.8 60 foot bears this out (3900lb car),
With that 60 a VERY low 13 or more likely a high 12 should be possible if the top end is doing its job. He's not making the HP

What did he shift at, I would shift that combo at 5500.
I agree. I bet that combo noses over if you try to shift above 5500.
With a 1.8 60', it should be capable of running high 12's. Does it pull hard all the way through the traps? Do you have a fuel pressure gauge to see if it is falling off?

before the season is over we are going to pump a lunati 240/250 520/547 cam that i have sitting around, my 4.56 gears & 4200 stall converter,only guessing do you think this would improve the et dramatically thx...
As it is now with a heavy car, stockish heads, low CR (9.5), low stall speed; that is about what you will get. Perhaps a tad better with tuning.
The 4200 will really wake it up, IMO. The proposed cam is about the biggest I would go at that CR, and I like Lunati, but I wouldn't be too quick to swap out the Isky. Keep the RPM below 6000 and it will be happier.

 It runs about what it should, not "way" off, just average. I also agree that it will like the changes and pick up a bunch.
