@ 10psi -- first pull was 551 / 587, but was getting a little knock and was too lean -- nearly 12.5:1 A/F.
We added more fuel, pulled a little timing for a safer tune and got it to 526 / 601 with the A/F sitting around 11.6-11.8.
Now it's time for another fuel pump or two. Fuel pressure dropped from 58 to 40 close to 6k.
The log manifold is leaking right off the first primary, so I get the joy of pulling all this stuff off to fix later this summer. Once I address the fuel issues, I'll turn the boost up to around 13.
^^^^ yes, i was wondering about that. i started to think that maybe he might be too rich, but he makes wonderful power with that AFR so...... my AFR is set at around 11.2 so technically im richer than him. and i have the back bumper to prove it

The motor is a low compression 375 with stage 2ex heads from Mike Morgan when he was around. It was supposed to be built beteen 8.5:1 and 9.0:1 compression, but he's since out of business, it's more of guess what's actually in it now. 
Cam is 218/218 .561" 114 LSA.
Let's see... drivetrain... spec stage 5 cluch, steel driveshaft, random tech torque arm, 12 bolt rear end. suspension.... lca's, 6 pt cage, kenny brown DD subframes, slp lowering springs, bilstien shocks. I'm sure there's some other stuff I'm forgetting as well, but those are the main mods.
Short term mods before I hit the track will be some brake upgrades and add a driveshaft safety loop. Add another fuel pump with a rpm activated switch, and dial the boost to around 13psi.... oh and buy some sticky tires.
All these mods are limited by pocket book funds, so if all goes well, I should be able to take it to the track in the next few months.
