To MILL or not to MILL, that is the question... I have the newer PRC Stage 2.5 5.3L (62.5 cc) heads as some of you may already know. I also run the MS3 cam on a 113 LSA, stock gaskets.
Combo made numbers in sig...HP is nice, but torque is a bit low. I decided to keep the heads. I am going to swap cams to something a little tamer with a more useable powerband for the street, something along the lines of a 228/232 112 (or 110 +2 like Pat G suggests to many people), G5X1, etcetc.
My poll is intended to get some feedback on whether or not I should mill the heads, run a thinner gasket, flycut, etc to get all my $'s worth out of the heads/cam combo.
I like the idea of just swapping the cam, it certainly easier, but if I can make the power I am making now, PLUS 400+ rwtq with the smaller cam, the money and time spent would be worth it to me...
I don't want this to neccesarily become a $ to power ratio poll, but I guess it is a factor.
Choose one of the options, and state your case.
The other helpful factor would be to suggest a cc to mill to, and a desired gasket thickness as well...Oh yeah, I only want to run pump gas, 93 octane.
THANKS!

Hey Pred....I thought about the MS4, since a lot of people claim the power band is better than its older brother, the MS3.....but isn't the MS4 still a hog of a camshaft?
I was looking for something more streetable...isn't the MS4 defeating that purpose, or no? I bet the peak power and torque with that cam and milled heads would be OUT OF THIS WORLD!!

This sounds an awful lot like the suggestion I made in one of your post weeks/months ago. If you do not want to flycut, then I think you should go with a cam very similar to what you listed (228/232, you know what i chose) and .040 gaskets. You would not want to mill your heads with that cam because I think it would put your DCR over the top. However, if you did mill the heads then you would want to go with a larger cam (like the MS4 or even your old MS3) but you would need to flycut. I do not remember if you ever posted your ICL, but I would suspect if you reused your cam you would want to advance it 4-6 degrees, but i would check with Pred, Pat to get there recommendations as they have much more experience with this than I do

Hey bud,
I remember your suggestion...hell I have had a lot of ideas thrown at me...I am just posting to get some thoughts from others...
All of you guys are a HUGE help!
Thanks

I would buy a set of trick flows, or ETP's, run around 11.5:1 compression without flycuting and run a slightly smaller cam if your not happy about the driveability.
The 228/232 is a good cam. I would do something along the line of a TRak or Torquer 3 myself. I personially believe there is some nice gains out of the aftermarket heads.
Not having to flycut is also a nice feature.
My suggestion.....
ETP 215 59cc heads. a Torque 3 or similar camshaft. Ported 90mm intake with a stock gasket. On the same dyno you made you numbers on another camaro with the 59cc ETP 215's, Torque 3 and non ported Fast 90 made 470 HP and 440 TQ.
THIS WAS THROUGH A stock 10 both just so your know.
But that is great power, and with a ported fast you could be in the same power range with the 12 bolt you have.

I just read a post of a guy who is going to run an MS4 on a 110 +4....that sounds SICK...and I think even though it is a LARGE cam, something I was considering getting away from, the 110+4 may bring the powerband in a lot sooner...
Anythoughts Guru's on a cam like that?

If you are thinking of the one I think you are, he has aftermarket pistons with valve reliefs.

The VEs of a Reverse will produce more trq, of course this comes at the cost of acertain amount of peak HP.
Even the 90/90 is a restriction (by design) as to how much air can be sucked in through it. That is why sheet metal intakes exist.

i think the ms4 or similar lsk intake / xer exhaust lobe on something like a 110 will net you some nice midrange and low end gains while picking up alittle hp also. flycut and get some .040 gaskets and run the numbers scr/dcr wise and mill acordingly to get up over 8:5 dcr and it should be a sweet setup and not have to spin the motor as high as you do right now.
