Are these the TQ20 specs: 214/224 @ 0.050 .512/.536 lift?
I've got one of those little puppies. Good low down little torquey cam. The only difference to my setup is I run an MSD ignition (not that it'd add much), I have stock 2V heads, valves & rockers and a weiand xcelerator. I need a little heavier springs but can't be stuffed waisting the money on this combo....so I lose a fraction up top.
So.....after rambling on.......I make 250-255rwhp.
I reckon you should have 260-270rwhp. It'll go great with those 3.9's. My 4.11's are too low for that cam....still fun though.
Sounds like you already know the HP numbers? C'mon, let us in on them
