thanks a lot. Where do you get the MS3 cam? What are the numbers for that cam? How is the idle?

462 rwhp? that would be great. What other mods to you have? I already have headman LTs, offroad y pipe, borla cat back, and an slp lid. With this setup it dyno'd at 346rwhp after a tune. I am really shooting for 450 at the wheels. I will probably put a little shot on it to get over 500 rwhp when the time is needed.

you get it from TSP,
237/242, .603"/.609" 112-114lsa, your choice.
idle will depend on the lsa, 112 on the rougher end, 114 is a little smoother. it also has ALOT to do with the tune. a good tuner can make most any cam idle well.

gotta question on my own setup, as it isnt together yet and im in afghanistan just waiting to get back home wrenching. been reading some threads lately that had me worried, so i mays well ask here and now about possible power numbers and ptv clearance.

-got a set of 5.3 heads, p&p, 58cc chamber. don't know who did the p&p and i havent seen the heads yet either. boo on me i know, but they were used and affordable until i could afford some trick flows or afrs.
-.040 head gaskets
-comp 918 springs
-stock pushrods
-comp r lifters
-f13 cam 230/232 585/595 112
-bbk 80mm intake
-bbk 80mm t.b.
-ceramic hooker longtubes dumped to 8" bullets
-granatelli maf

car is a m6 with a stock gear 10 bolt, and minus heads and cam the car made 375/360 at the wheels.
do i need to be looking at injectors?
any opinions on what im going to be looking for with the heads and cam? sorry for the hijack lol

MS4 Will not clear with those heads But MS3 Will.

Get MS3 with those heads its great combo with alot power.
