thanks for the comment, here is info i have on the head work: IA heads worked, twin plugged, with all the other mods, electronic xdi box and pods Head Heights: 3.573 total chamber volume 93.2cc IA new cam blanks ground to match up with IA headwork.
Intake fully open: .455
Exhaust fullt opem lift: .401
Retainer thickness: .200
Cam timing is 1.7 with 1mm lash overlap. Please set 1mm cold.

disclaimer: i'm no mechanic, but i would think with the $$$$$ spent on this engine, i would have hopped to be in the 400ish WHP range which i would think i'm missing about 100hp at the engine.

my rpm solenoid has the 5200 chip in it....not sure if that is correct but thats what they have in it.

appreciate the help.
