[QUOTE="swampratt, post: 2699597, member: 15054"] I went to ABEL Racing yesterday as Wednesday is dyno days. I made a couple pulls and checked Air fuel ratio (AFR) with the 600cfm edelbrock carb I jetted. I played with timing. 4 degrees more timing worked well from where I had it and my AFR at 2700rpm cruise was 14.0 I had it pretty close. The 4 degrees less timing was my 87-89 octane tune. I tested it with 91. It has 10.87 actual compression iron 305 heads and a 260H comp cam. iron ex manifolds and stock Qjet iron intake. I will go back in a week and dyno it with a 750cfm Quadrajet carb if it ain't raining. Then I will stick on a performer rpm intake in place of the stock cast iron Qjet intake and see what it does. 40 bucks of knowledge. I hope to break 200HP to the wheels. current best MPG is 17 cruising at 2800-3000 rpm, I could use a 4 or 5 speed stick with overdrive. wish I had one. [/QUOTE]
