I have to add timing info and carb info when I get a chance. Car has been so reliable in over 500 passes down the strip since I built it, that I kinda forgot most of my tuning data! LOL gotta love LS engines!!!!!!!!!

Here's a special treat for the few people fine-tuning edelbrock carbs:

engine: stock '02 5.3
heads: stock
cam: stock 191/191
intake: Edelbrock RPM Dual Plane
carb: Edelbrock Performer 600
squirters: 35 front/strongest pump shot
timing: Daytona Smartspark curve #9
jetting pri/sec: .095/.100 (#395/#400)
Primary metering rods: #6847 (.068/.047)
Step-up spring: Custom spring tailored to high vacuum opens at ~18" hg
Idle air bleed: .062
Idle by-pass air bleed: .040
Main air bleed: .040
IFR: Stock (.030)
Secondary metering: stock
rear gear/trans: 3.36/M20
car: 1969 Pontiac Firebird

The edelbrock Performer 600 really shines once the circuity is understood and fine-tuned. The step up spring can be easily replaced for a high-vacuum engine (stock 5.3 cam pulls 22" hg at idle) unlike the holley PV. Cruise ratio above 45mph is 15.0 - 15.5 and at lower revs is 13.5 - 15.0. Car is snappy and gets excellent mileage. PM me if you're interested in some tips on tuning these carbs.
