I need a new cam for my TPI- What is a good lopey low torque, daily drivable cam....
Ok- I need a new cam- mine is junk lol!.. I am wanting to go with something that would be the equivalent of a "hot cam" and still give me low end torque and great power over what i had, as well as maintain daily driveability.. I was looking at a lunati hyd. flat tappet cam( b/c i already bought lunati hyd. flat tappet lifters)
The lunati specs are as follows:Brand: Lunati

Would this be a good cam to go with, or does anyone have any other reccomendations?

Not trying to offend you my man, but if you would read the description of the cam it says right there they are Hyd. flat tappet.. And as far as the Lopey/ low end performance- you may be right . lol..

I was refering to the CC305 and CC306 cams mentioned as being roller cams. Sorry for not being clearer. No offence taken.
Ahh, i see- we are on the same block now.. lol

Can we assume it is a non-roller lifter block? If so, forget the cc cams mentioned.
Right- not a roller lefter block,
Ok- well i can kinda figure out that much, but, here is what im looking for- i have one hell of a top end for that motor- the votec's, But i need more on the LOW and MID powerbands.. What one of these that i've listed on here be my best shot at obtaining that? Also please notice the differences in Lobe Separation Angles.. Thanks!!!

I think that xfi cam you mentioned would be a good one. That's a lot of lift for little duration, 'specially for a FI type of cam, hmm, must have WILD ramp rates. I'll have to look into that more.
