Stock cam
#3
ok wise guy
I'm trying top to pick my cam, it will be the 218/224 on a 112 lsa or the 224/230 on a 114 lsa. I cannot decide!! I don't want to loose any low end power, not that I will tell anyway since I have never ran my LT1. The 218 sounds like a better match for my stock heads, but the numbers that 224 throws down are really impressive. I'm running iron heads, so I'm thinking the 224 might take advantage of the slightly better flowing capabilities of these heads. I will be polishing them up a little, but nothing major.
any input, what would you do?

I would recommend the Comp Cam 305 for what you are looking for...it's a 114 lsa, so it still has good low end, and 220 degrees of intake so it will pull all the way to 6200-6300 rpm (specs are 220/230 .544/.544 114 lsa (lift #s w/ 1.6 rockers). I have it in my car, and didn't lose any low end on the dyno to mention, and I get comments from people all the time about how it sounds (idles, etc), and esp the power it makes. My cam has a VERY definite lope to it, people always comment on the "roughness". I can have 3 people in my car and when I get on it, hardley even tell. Like tonight I took a couple of my friends for a ride, and could hardley tell they were in the car. It rocketed through 1st and 2nd gear in a couple seconds. Definitely a good cam. I would recommend it for a daily driver over a large cam or even the XE224. This is because I have seen more positive results with the CC305 at the track, where it really matters compared w/ the 224. There's guys on this board running 12.0s w/ stock heads, and some w/ ported heads, etc.
If you do decide to get the XE224, make sure you go all out on the springs and get dual coil springs, enough to handle the steep ramps of the XE grind. Otherwise, you'll be disappointed when you hit 6000 rpm and your power disappears completely.

I plotted the CC305, the XE218/224, and the Hotcam vs my LT1 with just headers, CAI and catback. All of those cams lose low-end TQ compared to me up to 3000 rpm. Above 3000 RPM, they make about 15-20 rwtq more.
Compared to a bone stock LT1, the cammed LT1's mentioned above make more TQ everywhere above 1800 rpm. They max out at about 50 rwtq more than the stock cam.
All of the cammed LT1's mentioned above were with headers and CAI. They make the TQ in a much more useful RPM range when going WOT.

allright, I think I've decided. I think i'll go with the cc305. compcams website says it makes power starting at 1500 rpm's. They give specs using 1.5 rocker arms, will it affect the power band going to 1.6's? I also noticed this cam makes good power all the way to 6000-6200 rpm's.
My other possible option is still the 224/230. How much do you think it will pull down the powerband on this cam if I went with a 114 lsa? I think i'll be happy with either of these cams, but i'm leaning towards the cc305 due to the slightly lower powerband.
Any final opinoins to help me decide? This has to be the hardest thing to pick for an engine!!!
thanks, matt!!
