i am interested in the Ms4 cam, which is 239/242 .649/.609 on a 111, not sure of the icl. Now if that cam is ground on a 110, how does it affect the powerband. I know it gives it more overlap, but will it provide more low end. I am looking for a larger cam with a nastier idle than my tsp 231/237 but want to retain some low end or even try to get more than the Xe lobed cam i have now. I also want to be able to rev to 6850 which is where i am at now with the 231/237. Am i lookng at the wrong cam for my needs? Recommendations are welcome. i can also fit some bigger cam since i have -2cc valve reliefs.

I do not have this cam installed yet. It is sitting in my room awaiting the supporting parts to install. According to TSP'S site the ms4 comes in 111 standard or 112 for smoother idle. I can tell you that the cam is slightly larger then what the site states. The ICL on my cam card is 110 so mine has a degree of advance ground in. I'm not sure if that standard or not though. As far as getting more bottom end then your 231\237 I'd call TSP and check with them. You may lose bottom end with the ms4 some of that will depend on your setup (heads headers) etc. According to my chats with TSP and the GMHTP article the cam will rev out to 7k peaking at 6400 with very minimal falloff to 7k. The good thing about you having pistons with reliefs is that you will be able to mill your heads some to gain compression which will improve you hp and tq. Just check with the head manufacturer if aftermarket and TSP for how much you can take off. Hope this helps you.

If I remember correctly from previous post they only offer the 110* as a custom order because p2v is an issue and flycutting is required. Since you have -2cc valve reliefs that should not be an issue depending on your heads. I have the MS4 with 111 and love it. As far as low end I don't think it is too bad at all. I'm still waiting to have some free time to finish my header installation which will wake up the car quite a bit. Now back to your question I would definitely call TSP they know their stuff. They can tell you exactly what you need to know. When I ordered the ms4 he recommended me to do the headers first as the ms4 is very exhaust bias. He said I would probably make 380rwhp with stock manifolds and ORY. I made 385rwhp. I knew headers where coming shortly so I ordered it an installed it anyway. Once I finish the headers the car should go to where it should be for my mods around 410rwhp cam only.

With the stage 2.5 heads and MS4 (111 sep) I can cruise all day long in 6th at 1500 rpms with no bucking /surging. Hell I pull a trailer with tires/tools for race days and never had a problem either. Stop and go traffic is a pain in the *** though

Im thinking that i might just go with the tsp torquer v.3 or maybe the highlift F14.

so can I use the MS4 cam with TFS 215 heads on stock block with stock piston's?

MS4 fits with stock heads . Trickflows have more clearance than stock , probably could even mill them .

I need to do alot more research but now I want to know which would be better? MS3,MS4,VRX1 or G5xx cam along with the TFS 215 heads?

Anyone know if the MS4 will work (without flycutting) with LS6 stage 2 heads?

MS4 will clear stock valved 2.00/1.55 non milled LS6 heads 64cc

I had the MS3 before my current MS4. Before the MS3 I had the TSP 231/237.

I was SHOCKED at how much more down low torque I gained over BOTH the 231 AND MS3'S

To answer your question: yes, you will gain low-end BIG TIME.

Dragon, could you post up some of your dyno graphs comparing the 231/237 and ms4. I would like to see how the two curves compare. If you have them.

Also it seems like the noticebale power starts to come in around 3500 with my 231/237. Is that how yours felt and how does the ms4 compare.

Thanks
