Im helping my friend find a good cam (he doesnt have the internet). however he does have around $200 -$250 for a new cam (hydraulic roller is a must) Here is his mods:
3.42 posi, ported plenum, airfoil, ported slp runners, ported manifold, ported heads, headers (no emissions left), ypipe, cat and hooker catback. I need you to help find him a good cam! Also it is more like a weekend driver than an everyday.... im guessing the lift should be a little less that .500 Anyhelp is appreciated.....

 

I love my cam (see sig) and a lot of LT-1 guys have great results with this cam as well (low 12's N/A with the usual goodies like you have). I got it for about $190 with tax and everything. It is a roller so if you don't already have roller lifters, you will need to buy them.

SLP has a similar cam as well. SLP actually has three different cams and their largest one is about the same size as the LT4 HC, just a little bit bigger. I think SLP's cams are a little bit more expensive though, more around the $400 mark.

The LT4 HC's specs are: adv. dura.: 279*/287* dura. @.050": 218*/228* with .525" intake and exhaust w/1.6 rockers. I think it would work well with your combo and it should yield some good power. It idles nice too... a little lopy but very manageable with a little PROM tuning.

TPIS's ZZ9 cam is a pretty nice one for our cars as well. I am not sure, but I think it is a bit smaller than the LT4 HC. It is also like $385 so that is likely not an option for you going by your budget projection.

And of course Comp Cams sells a bunch of cams that work great for our cars. I think they are in the $250 range for our cars (if you already have a roller motor and don't need lifters). I have heard time and again that Comp Cams makes the best cams in the industry and I know a lot of guys with very fast cars that swear by them. Somebody with experience with Comp Cams can tell you which ones are the best for our cars, or you can call them if you don't get any responses form here........

Good Luck.

LOL get this..... hes still got the 305 TPI auto PEANUT CAM with all that stuff! What are the horse and torque number gonna look like between the Hot Cam and the ZZ4 cam???

 

I got the LT4 HOT cam for $165 from www.gmpartsdirect.com. It sounds like it should work nicely with your friend's application.

Is the LT4 hot cam and hydraulic roller..... I also forgot to say that the engine is a 305 TPI. Does that make any difference??? Also how streetable is the LT4 Hot cam??

 

Read my post above again.

I think i remember somewhere on here where they make just an LT4 Cam, a little toned down compared to the LT4 Hot Cam..... Is this true? and where can i get one? I want to keep if a little below .500 on the lifts

 

that would be the gm 845 cam my friend.

There's a difference between the stock LT4 cam and the GM 845 cam. The stock LT4 is something like 203/210 and the 845 is 214/220. The 845 is slightly milder than the LT4 HOT cam, if thats what you meant...

For a 305 TPI I wouldnt run the LT4 HOT cam. Its been done but I personally think its too big. Go for the ZZ4 or 845 cam.

 

Someone please help me with this one. How much hp/tq am I missing out on by using the cam in my sig vs. a LT4 Hot cam or similar. Would it be worth the upgrade?

Anyone?

 

Scott,

The ZZ3 cam on engine analyzer made 3 more hp and 6 more tq than your current cam.

You cam made 339 hp @ 5000 rpm and 408 tq @ 4000.

The hot cam made 360 hp and 423 tq at the same rpm, and the LPE 74219 made 362 and 424. The CC 210-220 made 342 and 413.

You make your own decision. Port the lower intake if you pull the cam.

 

Great info, man! Thanks! I knew that my cam was on the mild side, but I'm pleased to see that I'm still close in power to the "big" ones. I'm not going to tear into my engine again just to gain a possible 20hp or so. I'll find a way to make up that difference somewhere else. Thanks again!!

 

Hey guys, sorry to change the subject just a big, but with emissions controls still intact, are these emissions passin' cams? Sounds like everybody knows their stuff in this thread, so I figure I'll ask here instead of starting from scratch.

 

Also dont forget that some of the cams require that you use 1.6 rockers. They cost more than the cam sometimes.

It looks like the ZZ4 cam doesn't require 1.6 rockers, so I'm going to do that swap.

My question is, would I see any benefit if I upgraded to 1.6 rockers in the future?

 

Uhm... which cams are those? I've never heard of a cam that required 1.6 rockers.

1.6 roller rockers all around will gain you about 10 horsepower. Just make sure the springs on your heads can handle the extra lift.
