Yes, that is true to a point... It had AFR that wasn't shown on the sheet for the Vicky and I did some tuning. It showed me that when the power valve opened, it went fat. Blocked the power valves and it improved and got the fueling into a range that is acceptable. By the way, it added 0.2 HP leaning it out but it is saving gasoline out the tailpipe. Pulling the slotted round air cleaners with the K&N filters, added 2.0 hp and leaned it out a half a point. Tells me that I need different air filters if I want to make the engine happier when I take a road trip. Dropping the exhaust off the header changed nothing appreciable...counter intuitive I haven't been able to tune this engine, hell these guys got their rocks off on the old school stuff and they charged $60.00 per car as much time as you wanted to spend on it. It confirmed that my seat of the pants was close but I have other problems. Installing a different cam to find out I had another un identified problem....it's worth the investment in my mind. We were at 8000' density altitude when we did this too. Additionally, I wanted to know the hp and torque numbers on the Riley headed engine. I was impressed with my $300.00 engine. Riley knew what he was doing and on a 5.5:1 head..... It was my trip to the casino plus there are some young guys that were at the dyno/performance shop that now want old school, banger stuff. One said daily driver and I believe him My buddy took his car yesterday and found out that his tuning was spot on and he did all kinds of things to change his numbers. It has a Lion III head with a single Stromberg 48 it did 53hp to the rear wheels and 133 ftlbs of torque on the best pull. All his timing changes, etc made 1.5 hp change. It's nice to have a base line to compare things to.
