interesting....something else to watch out for when buying flea pay parts.

 

These were all brand new parts not used

 

have a 103 build with 255 cams original. then the next winter I got mva heads had to change the pistons to the 10.5 :1 to match the combustion chamber of the heads. cold cranking pressure is 212 psi in both cylinders. hooked up acr's no way it will turn over with out them when its hot. Have se tapered pushrods, vance and vines power duals and monster rounds was hoping to get 100 hp but didnt quite make it. The dyno guy spent about 1.5 hours on it but i dont think he really did anything but try 2-3 programs, once I got home and pulled the info off the vci and looked at the program its exactly basic right off the se race tuner files he didnt do any ve valve run changes no timing changes and had all the afrs except the last 2 columbs at 14.6 when i asked during a phone call i was told they only worry about wide open throttle runs. sure isnt what I expected for the 400 bucks it cost me. set all my afrs at 14.1 in most rows and set 2500-3000 at 14.3 for crusing gets 42 mpg us and flat roads and 40 on hills. about in town.
