helooo guys....and masters...
please teach me bout a best camshaft setup i should choose...
right now my engine is 4.0L all stock AMC 242 6cyls... with 60mm TB and 30mm spacer... also piggibacked and rev limit removal to 6500rpm....
i need a decent camshaft which can give me power from very early rpm....
im using this motor for offroad competition
and the track has a lot of hillclimb... towing... winching... and extreme superball
see if anyone can help me to choose the best cam....
so far my eyes cought into compcams and crower

 

Have you looked into building a stroker?

More people talk about stroking than caming the 4.0 motor...

 

we have 3 cars in 1 team for the race competition
2 of the cars should reach finish box... thats how things work here

and the first car is already 4.5L stroked without cam.... its efi and tuned by me on mainline chassis dynamometer awd1200

the point is the second car with the second driver which is lack of experience and stil very young at the age of 15 is very reckless..
i need to lecture him till he can master his car on his 4.0L
and my target is to have a proper cam to at least give additional power to the second car so the gap between 2 cars is not so far....

 

K.

Have fun with that.

 

I would invest in a big valve ported head before a cam. Head flow sucks.
Like-
505Performance or Newcomer Racing.

 

any sugestion or reference how to port the head bro...
please lecture me

 

thanks bro....
