Hi chuck,
yes the hp is with exhuast only. not sharktuning ....next dyno will hopeflly be in 2 weeks as the raptor sc , cams and 24 lb fuel injectors are just now installed and have really awakened the engine..
I have started on the stroker short block as the low end torque hasn't improved any really with all the above stuff and I would like the improvements to be all through the rpm range..
