408 Stroker

dont think about a cam till you get your pistons and compression ratio worked out
what kind of jeep use, what gears, tires
lots of difference with a rock crawler application and a off road racer or snow plow
do you have a 4" stroke crank
the piston stock crank combination will give you a very low compression ratio
Speedpro h116cp or kb107 are the pistons that will get ya there..
Speedpro H405 pistons, what to expect for performance?
do some research
which heads- casting number please
do the math- get the results you MUST learn how to calculate deck height/clearance, compression ratio, etc
