Peak Horsepower: 360.4
@ 5500
Peak Torque: 405.0
@ 3500

this is with hp ported 2.02 1.60 heads a 256/268 duration .447/.454 lift comp cam (hydralic flat tappet) 10 to 1 compression performer intake 600cfm carb small tube headers
this is at a 4000 lb weight
it should say performer behind the carb close to the firewall
or if its a performer rpm its in front of the carb
the 260 will cut your torque and hp down
