MS3 or FM13
The Best V8 Stories One Small Block at Time
NONE OF THE ABOVE
I had the TRak cam, as you know and maybe it's just that I'm paranoid but those Isky LS-K lobes worry me. I don't like the idea of having .649" lift beating up my valvetrain (rated at .650" lift). I've been doing tons of research lately and looking into cam specs beyond just the duration @ .050" and lift. For a streetable, and most importantly, easily tuneable cam, I'd recommend sticking to FMS/Cam Motion lobes or Comp XE-R lobes. The FM13 is a Cam Motion grind, and the MS3 is a Comp grind, but neither are my choice. I have to agree with SVT THIS, about the G5X4. In terms of size, it's damn close to the MS3 in terms of size, but seems to dyno better and respond better at the track. It should idle about the same, and, having a lower LSA, it's actually a better grind for our motors, which ideally need a 110 or 111 LSA. I've seen an easy 430rwhp cam only with the X4, and a consistent 10rwhp/10rwtq throughout the curve over the G5X3, and idles just as well. You have a 6-speed with gears, which would make this cam perfect for your car. I would go with the X4 myself, but I don't want to change stall speeds. I do stand behind it 100% though. I just ordered a similar, slightly smaller, custom grind, a 234/242 on a 110 LSA. So it's basically a few degrees smaller than the X4 to match my setup. PM me, because if you want I can get you a brand new G5X4 for cheaper than LG can get it to you. IMO, it may be the perfect LS1 cam.
Unfortunately, you have to pay taxes on it, though
I've heard plenty of awesome things about the MS3, and I have been considering getting it for myself actually. I have since changed my mind, and will be going with the Torquer V.2 to help out a little with the daily-driving along with get some very decent #'s. You should check into it, pretty gnarly cam
