The Z28 probably needed the driver mod

the 4.30's were fine with the 28 tire. Even when i spayed 150, she went 10.60 @ 132 @ around 6900.

here is a link to the video. http://videos.streetfire.net/video/f...ad00c3588a.htm

This is when i first put it together and got all the bugs worked out. Best all motor was 11.60@121. Before anyone says anything about the long crazy burnout i was pissed because i couldnt get the mt drag radials to hook. You can see it spin like hell.

I know that I will loose some low end but, it will get better traction on the street and when I want to launch hard I'll just spray it.

3.73 gears with spray at the take off and a 3800 stall, sounds good to me! Streetable yet Vicious at the track!

Probly be best with 150 shot off the line.

Like posted above, if you get heads with a certain valve size or they are milled, you will have to flycut. Your stock heads, or the stage 1 PRC LS6 heads will not require you to flycut the pistons. But if you went with like the 2.5 PRC's or a large set of Darts or AFR's, then flycutting will be a must.

I plan on getting the MS4, and I have been doing a bit of research myself lately. I am trying to get the best combo for the cam without spending the extra cost of flycutting the pistons. This cam really is big, and to take its full potential, you will really need a good intake like a FAST 90/90, and a good set of heads. The PRC stage 1 LS6 heads will be a bit better than the stockers, but with how the cam wants to really breath, it will undoubtingly be more benefitial with flycutting the pistons and going with some much larger heads like you are thinking.

I am also considering just going with a MS3 instead, and then going with some bigger heads to make up the power difference and still avoid flycutting, but I am still trying to figure out if the MS3 with a killer set of heads will give me more power than a MS4 with a stage 1 set of LS6 PRC heads would.

yeah i have heard from a few people that milling takes away from air flow i tried to do a few searches.so i guess everything has its ups and down if anyone has used a stg.2.5 head chime in with your thoughts thankx

I've ran both the ms3 and the ms4. Both are great cams. I would say the power difference would be 10 or less rwhp. Tsp told me that a set of stage 1 prc ls6 heads and the ms4 would be around 460rwhp with a 6 speed. I've seen cam only ms4 90/90 set ups put down 430. Not sure on the ms3 cam only numbers
