Yes another cam question! TF 220's I have been searching the forum for about a month now for cam specs and now that I have ordered a set of heads I have narrowed down the list.
Ordered a set of TEA Trick flow 220 as cast heads and .045 head gaskets that Mike recommended. They are installing pm guides to run stock rockers, springs that are good to .650 lift, doing some hand blending under the valves and milling them to my spec (as of right now my spec is 63cc).
I have a week or so before I have to give Mike the final say on the CC size so I'm trying to decide on a cam to match to the heads so that I can get the right static/dynamic CRs.
The cams that are in question are:
230XFI/234/XER 114+2
231/235 (Mike had mentioned something in this range, custom ground)
232/234XER
235LSK/235XER 114+3
235/239 (kinda leaning away from this one for drive-ability concerns)
I want to maintain good drive-ability with a nice tq curve. Looking to get somewhere near 490/450 at the rear.
Supporting mods are Callaway honker, LG 1 3/4 LTs, h/f cats, borla exhaust, Fast 102
Car has stock gears and is a 06 Z51
Flow #s on the heads should be a little better because of the blending but here is what they are stock from TEA
.100 67 52
.200 139 114
.300 220 174
.400 269 210
.500 301 227
.550 310 232
.600 310 237
Thanks guys
