A little bit milder cam. Everything Optimized. I punched in IN 220 @ .050, EX 210 @ .050. IN .460 lift, EX .470. Inbetween stock and Jose grind. 17" vacuum at idle of 800RPM. 15 initial and 32 total @ 3000RPM ignition timing. Mild head porting and 2.9 valves. Offy intake, 390 Holley, Headers. Cam @ 5 advance(1 tooth). Advertised duration probably around 270 intake 260 exhaust. Still showing lean under 2000RPM. Trying to install a scanner to show chart. 195 FTLBS TQ @ 4500RPM, 190 Flywheel HP @ 6000RPM. That would be approximately 152 @ rear wheels. Remember this is a computer program and hypothetical.
Performance Trends Engine Pro. I'm having issues installing the scanner to show the graph. I'll figure it out.
Guys, Here is what the program shows: Cam straight up 8 to 1=5.5, 9 to 1=6, 10 to 1=6.9, 11 to 1=7.5. 4 degrees cam advance 8 to 1=5.8, 9 to 1= 6.5, 10 to 1=7.2, 11 to 1=7.9. 8 degrees cam advance 8 to 1=6, 9 to 1=6.8, 10 to 1=7.5, 11 to 1=8.2. This tells me ideally you should have 10 to 11 to 1 for straight up. 9.5 to 10.5 to 1 for 4 degrees advance. 8 degrees advance 9 to 10 to 1. all graphs in the 7 range show 190 to 200HP. I'll do a chart with a lower duration cam next.
Mike, Does the 2.9 crank put the piston at zero deck without decking the block? The longer stroke will change the Dynamic number. The calculations were done with a 2.8 crank stroke. Are you sure you only have 9.3 compression? I'll run the 2.9 stroke to see the difference.
So with my build plans; 2.9 crank,2.9 valves, .030 over bore, 0 deck height, and rough calculations show 9.3:1 CR, offy intake, Holley 390, it looks like I would need to run one tooth advanced on the cam.
One cam tooth=5.3 degrees.
