How much different are the CC305 and the CC306? I pretty much planned on the 306 but I might step back down if it's gonna be a pain to drive every day. I have a 3000rpm stall and 3.73's if that makes a difference.

I am so getting that when I get my taxes. UNDER $500 and I can have the Hotcam kit. That is absolutely amazing considering a cam from Comp Cams is like $250. Of course, one has to wonder what is the quality of the springs included in this kit. Are they subject to valve float? I doubt I'll go too far over 6k rpm, if that even.

Jason Cromer has the best deal on the HC kit, AFAIK.

You hear that alot about the Hotcam springs, but the fact is that guys are going 6200 RPM with that kit no problems.

You can get the Hotcam kit even cheaper here:

Good lord. I'm going to get very very anxious. I think the price alone has settled it for me. At first, I will probably be disappointed, unless I save up for LTs and a stall before I install the cam. Otherwise it will be going through stock stall, manifolds, etc. It'd probably still give me a good amount of power increase over stock. Will the 1.6 RRs included fit under stock valve covers as well?

Andy, you've already got your answer. The hotcam kit, for the money is what you should be looking at. I don't think a big cam is the answer for you. You need something that is going to make torque, not high rpm power.
Hotcam, longtubes, and a good converter and I think you've got a 12.50 car. And of course I'd do the tune for you.
Great example is Darren's car. Exact same thing as what I described above with 3.42's. It's gone 12.70's and there's more in it, I just can't find it. It makes good power, it's just not getting down the track quite yet. But remember, his car was a pig stock too...it was a consistent 14.30 car with the 2.73's and would only run 13.30@99mph with shorties, 3.42's, and a converter. Car has just never mph'd. I'll get it this year though, if it kills me.
Get the HC kit and be done with it. It'll go mid 12's.

Dan K,

I was wondering when you'd chime in. I think I'll get Long Tubes first though. Just to get that out of the way. I was wondering what Darren's car ran. I was hoping you'd do the tune...well, for a price of course. Actually, if you wouldn't mind, I'd like you to do a lil' modifying to it as is. I hear you can squeeze a bit of power out of a stock car. At least once it get's nice enough for me to want to drive the car. I figure mid 12's is something decent to shoot for. With you doing the tune Dan, I'm sure it'd get there. You're gonna have fun with Brian's car in March.

Also, what converter should I be looking at? 2800? 3000? Personally I think anything higher than 3000 may be too big for a Hotcam, but then again, I have much to learn. I might not get the Hotcam kit this year, especially after doing LT's and gears, but damnit, it's gonna happen someday.

Then just do the longtubes and gears this year.
You can always get the converter when you get the cam too. It'd be nice to have it before though.
Shoot me an e-mail in spring and I can get a program for your car. Be really nice to set the fueling up at the dyno in march, or just at the track...either way would work.
I'm still looking at getting a wideband...everyone would just need to get a bung welded into their exhaust somewhere. No biggie.

if you're gonna be runnin street tires i think anything below 2200RPM stall will be fine (no sense in making itharder to get off the line if you aint got proper tires) if youre runnin somethin like slicks then 3000 or above wont be too big.

I don't have any traction issues with DR's if I heat em up real well. 3k stall and 3.73s. I do take it kinda easy at first though, cause it will break em loose if I want to.

I just installed a 230/236 112 LSA from comp cams, and WOW... who says big cams dont make low tq? I can say that at 2krpm tq is a beast, and at 3k its even meaner. I havent taken it past that though yet... 300 mile break in... I like the tq kicking in right at 2krpm like this cam does. Seen many people dyno in the 350 range w/ this cam and stock heads too....

The gears are definitely a for sure thing. Longtubes will probably come along a lil later in the year, depends which one I wanna do first. Setting up the fueling at the track would be cheaper than the dyno, but probably not as accurate. But then again, I don't know everything you can do with that laptop Dan. You'll have to explain wideband to me. I've heard of it, but know nothing about it.

For stockheads with an automatic I would suggest my cam or the Hotcam. Ken95z ran 11.80 with the hotcam with stockheads. Frank95z
Your car is the reason I started looking at the smaller cams. Everyone seems to assume, the bigger the better. Not true. I have been looking at small cam/stock head cars for about a year and they run just as strong as big cam/heads cars do. They put up similar mph and et's. The 210/224 and hotcam match the stock LT-1 heads so well b/c stock heads have big intake and small exhaust. The intake/exhaust duration of these cams make up for the heads ddesign flaws.

Has anyone tried to port match their heads to their XE 230/236? I'm not talking about a full-out port job for maximum intake/exhaust durations at .600" lift, I'm talking about matching the mid-rpm's to those of the XE 230/236...

Thanks!
