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 .

 

I was recently reading a thread that Tony Mamo said you wanted close duration and close lsa with those heads. Looks great let us know what it makes

 

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.

 

Anybody else got opinions or suggestions about this setup?

 

When ya gonna shift? Is this a dd cam or track? need more info man

 

The car is not a daily driver; gets driven a few times a month. Will mostly be a street car, but will see some time at the strip. Looking for a cam that has good power under the curve, yet still pulls hard up to 7 grand.

 

I had almost the exact same setup afrs milled to 62cc with a 230/234 111+2 lsa had a lopey idle but also drove very well however it peaked around 6300 or so but the power didn't drop off much after peak even up til it hit the limiter at 6600

 

i dont know if AFR makes the 205. I believe they have the new 210 heads or 215 heads.

 

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

 

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.

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.

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!

I see what your saying. So which one of these would you suggest. 230/234 111 LSA or 230/234 110 LSA. Will there be that much difference between the two? I want something that's going to pull hard up till at least 6500, yet still give me good under the curve power.

 

I have the heads already; bought the AFR 205's used.

 

Splitting hairs between the two. 110 will chop a little more, plus help the bottom end. For as little as you can really use the upper end on the street, I would lean towards the 110.

 

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.

 

Thanks for you help. What lift would you suggest on a 230/234 110 LSA?

 

Ok, sounds like I'm on the right track then. In your opinion, what lift would be good for a 230/234 110 LSA cam based on my setup?

 

.580 - .600 range will be plenty

 

So I've decided to go with a 231/234 110 + 0 LSA. Anyone know what my powerband will look like?

 

Peak HP @ 6200 rpm .. peak TQ @ 4800 rpm .. shift it at 6500 rpm ...
