No the crank is a 4340 steel with 5.7 h beam rods and Forged pistons comp is 8.2 /1 supercharger is a T Trim all with 3 " piping and a intercooler. the power drops off when belt start to slip at 5500 rpm
COME stroker? the Ttrim is a decent blower, capable of meany PSI. i didn't know they run of a serpentine belt setup. though they always used the timing belt/gilmour style drives.
you running maf or map? if maf i suggest you get a bored out MAF sensor from MACE engineering (will need a retune to use) also get there plenum insulator (reduce intake temps) and plenum spacer(gets better manifold air distribution). both of these have proven dyno gains. also do the EGR gasket support plate mod(helps reducing intake temps when EGR opens:whistling).
if you are running maf i suggest maybe changing to a MAP setup. the people from kalmaker can now do this on the ecotecs and have seen some good results but still get the MACE insultor and spacer.
