How does this setup look? Would this cam work well with my setup? 2002 WS6, 6 speed, with long tube headers, dual exhaust and AFR 205 heads, which are milled to 62cc. The cam I'm thinking about is a 230/234 110+4 LSA. Will likely have the cam ground by Futral Motorsports. Does this combo look ok and do you think it would get me close to my goal of 450 rwhp and still have a mean *** sounding idle. I'm open to suggestions as well, so please come in and help me out.

I would say it should give you what you want and maybe even a lil' more. I'm sure FMS will hook you up. It seems I'm one of a few FMS fans on this board,so I know what you are getting. Go for it and keep me/us posted

So close duration would mean more along the lines of 232/234 or even a 230/230? The reason I'm wanting it on a 110 or maybee even a 111 LSA is for that choppy, mean sounding idle. I've been doing a lot of research on longer and closer duration, but seem to be getting even more confused. I'm also going to be running my stock LS6 intake for a while, so not sure how that plays into it.

Let me put it this way someone was complaining about the afr heads and had a 230/238 115 lsa cam and tony told him first thing that had to go was the cam. and also said that for N/A setups nothing over 114 was good for those heads the smaller the better. I think youre in the right range and with that advance in the cam itll make good power sooner

It all comes down to where you want to make power, and balancing the valve events for that goal with what the engine wants. If you keep adding duration without closing the LSA some, you end up with a cam that peaks so high you cannot use it.
Good luck!

[QUOTE=hammertime;14114578]Tony chooses valve events to suit the customer's plan when he builds an engine. If you are familiar with the "Blue Pill" combo, he uses a 4 degree split in favor of the exhaust and a wider LSA with just enough duration to get the job done.

4 degrees of advance will close your intake valve at 41* ABDC. Your power would peak about 6100 rpm and be pretty well done by 6400-6500. If you really want it to pull hard past 6500, get it ground at 110+0 and install it straight up. You need that split to the exhaust to keep pulling in the upper range, but your IVC needs to support the goal as well.
Good luck
Phoenix ... Hammertime is correct on this...go with the 110 +0 LSA on the cam ... those heads will like the smaller duration and the lower LSA numbers for sure. If you wanted to go even a little lower on duration that combo will still work great.
