Just reading some old posts and I wondered has anyone ported the heads on the ISF with good gains, also were any after market cams made with results. I know there are only a few people on here that will be able to answer this ?? Lowbux

 

rr racing's building an engine and will have results later on be patient , also they already build an engine with forged pistons and installed a supercharger on it

 

Be patient my #ss this car has been out for 9 years and only one company has done this ???? I know about there supercharger, is there any posts on after market cams cheers.
