yet another cam question I'm rather new here, and not exactly road race, but I think road racing is closest to my application of drifting.
the setup will be in a nissan 240sx tipping the scales around 2500lbs. with me in it.
Motor:
- stock bottom-end
- PRC dual valve springs + titanium retainers
- Hardland sharp OEM rebuilt 1.7 rockers
- Comp 7.400" hardened push rods
- Typhoon intake manifold
- 90mm throttle body
- 42# injectors
- Electromotive TecGT engine management
- custom long-tubes w/ 1.75" primaries
- ARP rod bolts
The engine will be running E85 for fuel and I'd like to spin it to 7k on a regular basis if safe/possible
From what i've found in the search (which is rather intermittent)
Is that I shouldn't go with anything too aggressive; i'm fine with that.
I have gathered, my best bet is a cam in the area of: 232/232 w/ around .600"/.600" of lift.
However, from what I read I need to really keep an eye on the ramp-rates and keep it more moderate than a lot of the drag race guys seem to like.
So, that being said; does it all sound right?
Any input, even suggestions as to what cam, or what I should expect, or do or whatever, i'm fairly new to the LSx stuff!
