how much HP am i running with these mods? HMF slip-on, Twin air airfilter with 6 holes in the lid, Hotcam stage 1.


And then what would i be running at with a 426 bore, JE 11:1 compression piston?

a 400ex has around 27 stock. I bet your mods now gave it a couple hp's. I bet a 426 with 11:1 that is jetted properly with your cam and other mods would prolly get well into the 30's in the hp department.
