Default 11.358, 120.62 @ 22 psi (thanks Jack)

Thanks Jack for the great engine!!!!!!!!!!!!!!!!!!!

1st run - boost: 18 psi, timing: 24/22, O2s: .79

60' - 1.870
330 - 5.079
1/8 - 7.808
MPH - 90.26
1000 - 10.155
1/4 - 12.112
MPH - 115.80

MPH pickup: 25.54 (I knew it was going to be a good night)


Added boost and pulled fuel...

4th run - boost: 22 psi, timing: 24/22, O2s: .77

60' - 1.674
330 - 4.690
1/8 - 7.272
MPH - 95.61
1000 - 9.489
1/4 - 11.358
MPH - 120.62

MPH pickup: 25.01

Over the winter I did the following:
1) rewelded DS header
2) flow tested fuel pump and moved the hotwire to alt
3) got new alky pump from Julio (BIG DIFFERENCE)
4) new plugs
5) increased the trans psi

Not too bad for a 10 year old LU 12" 2800 convertor and stock MAF.

WOW!!!! That's great, your numbers look pretty darn good. The best part is you aren't even leaning on it yet. Heck, work on your 60ft, maybe a lb or 2 of boost and you've got an easy 10 second car!!!

Right around the 1000' mark the thing pulled HARD. The above runs were with a 5000 2-3 shift...I'm thinking there's a few MPH left on the table. Need to shift 2-3 at 5500 maybe 5700.

Yep, definitely could improve shifting 5600 to 6000 rpm.. give it a shot.
