Sorry if this is a newbie question, but can you run a MS4 cam on the stock 241 heads and not have to do any flycutting. Is there anyone running a set-up like this or no? What kind of power are you making? Also if no one is running this, why aren't too many people doing it, too big of a cam for the stock heads?

TSP says you should be okay, depending on the LSA, but I would measure it anyway just to be sure. Taking the time to measure everything is a lot easier and cheaper then bouncing a valve off a piston

Yah, that is good advice.

you should be fine on a cam only swap, people start pushing the limits when they mill the heads, get bigger valves and so forth. But the cam really does need a set of ported heads to show its true potential.

as long as you get the cam on a 111 or 112lsa you will be fine without flycutting.

not to hijack your thread or anything, but does anyone know what the ptvc readings are on stock heads and gasket? I have tried looking all over and can't find anyone that has actually measure it. I'm about to plug an ms4 into mine. If i can't find anyone that has i will post it up when i get mine in.

If you ported the stock 241's, will it be pretty good with the MS4.

yeah the ms4 is fine on the stock heads... as long as you dont go under 111LSA then you should be fine. about porting the stock heads, i would look into a set of new ones b/c on a good porting job your looking close to around the same price so if thats the case spend a little more and get something better

I am also on a 110lsa, but I have a forged motor so I didn't have to worry about flycutting.

How do you like the 110 lsa so far? The motor will be forged eventually..

What CC valve reliefs are you runing? Dyno numbers?

Thanks

I love the cam now that it is tuned, I am running -4cc reliefs, have not had a chance to get it on a dyno yet, but with all my mods I should be knocking at 500hp's door.

gen accepted were .120/.100 now everyone is going with .100/.080 PTV clearance

MS3 MS4 T-rex g5x4 etc etc come ALOT closer then the generally accepted amounts

call texas and they should be able to give you the actual measurements they've found
