Nothing special, just your run of the mill conventional headed big block with a fogger and a plate. It's mild. Freshened by Pascal at L&L engines in Michigan, probably one of the most honest engine guys in the country. he races top dragster out in the Midwest, and consistently goes in the 6.50 range at over 200, with a normally aspirated 632 to boot!. Racing against a field of nitrous and blown entry's he qualified this year in mid pack with an n/a entry, man knows how to make power!!
