850's and 1600's... what fuel pump should I use...?
I'm noticing some hesitation under load... I'm starting to think that it is my FP not putting out enough. It just kinda "misses" There could be ton of stuff wrong, but I was unsure if my RP fuel pump would be adiquate for that much fuel foing into my motor... Thanks!

Motor is weak anyway... need to be carful.The jacobs should be wired so that you can join the stock wiring back together without the amp. I'm guessing you used the GM connectors RP supplies with the Jacobs.
Hey, where did my $$$ go?

If it were me (which it isnt) I'd just run a single MSD on leading with the stock coils and I'd also pull out those 11's till its time to tune. Your just going to foul them since your car isnt tuned.
Also, I'd ditch the J&S, it only retars leading and can cause negitive split, especially if you run a pretty tight split to begin with. If you get tuned good you shouldnt need a J&S.
BTW - How much fuel pressure are you running at idle???

40psi... I pulled the wires to the leading and put the trailing in their place... I'm not exactly going very far... I probably won't drive but mabe50 miles the next couple of days. I'll probably swap plugs though... those damn 11s are expensive! Sweet... polished manifold and TB just showed up!
