Here's what the rebuild shop was recommended after talking to another local shop anyone using it? Is it too close to LT1 factory?:

This would be a nice improvement over the factory LT-1, especially if you used 1.6 rockers. It should have a good idle, and lots of low-end Tq; very streetable. Cam choise depends a lot on what you want from it. The bigger the cam, the more high RPM power, at a cost of low RPM power. Also with a big cam, you need to complement it with better heads, intake, exhaust etc. It's all about the combination.

 

Good point on the rockers, which we have to order anyway, thanks

 

For an LT1, I'd go with a 305, esp if the heads have been ported.

 

Would it (the 305) require a new chip? Any idea if it (the 305) would be safe for (NJ) inspections? Maybe I shackled myself when I told the folks who recommended it that it must pass NJ inspections - it should, but it doesn't have to pass comfortably
Would the 305 sacrifice a little on the low end torque compared to the 304?

 

It's a HOT cam on 114* lobe center instead of 112*. More low end than a HOT cam, plenty of high end for an LT1 w/ported heads. I'd think about a 304 in an L98 or in an Impala SS (heavy) but not a 3300 lbs Vette.

It'll pass IM240 w/long tube heads, as long as you have cats.

I plan on keeping the cats, so now I'll have to hunt up a good deal on LT headers.
If the 304 has plenty of Low end, more than the HOT cam, and plenty of high end, why not in my '92 Vette? What would the 305 offer as an improvement? (I'd buy a different cam - LPE, Crane, whomever - it doesn't have to be the Comp Cam, which seems to be the preferred cam and IS fine with me!)

 

305 will make more HP than a 304 esp on an LT1 w/ported heads. The 304 cam is more like a 219 or ZZ3 cam. Those are good for an L98, but an LT1 w/ported heads is going to breath more, I'd choose a cam that matches the heads/intake. That's why the HOT cam and the 305 are the most popular LT1/4 cams, they match the heads/intake sooo well.

Eric

 

If I do not port the heads (put the $$$ into LT headers, for instance), would the 304 be a better match? (I'm still probably going to go up to the 305...)

 

The 305 or LT4 Hot cam will still make very good power on stock heads. That's why I really like the LT4 Hot Cam, it's an extremely versatile cam for the LT1, it works very in a stone stock motor or one that's been fully dressed out, or any combination in between. The CC305 makes very similar power and should behave the same way. If memory serves the CC305 is just a little milder because of it's wider lobe seperation, which would make it pass emissions easier, although the hot cam will do it with some tuning.

 

I went with CompCams 503.....pretty aggessive street cam..

Have you looked at CompCams 501 or 502?????

I am not an expert, but out of ignorance I finally came to the conclusion that the 500 series cams were a little better than the 300 series cam...

Then again the HotCam is also a good choice....

 

I hope this copy and pastes right:

[QUOTE=LT4BUD]
Have you looked at CompCams 501 or 502?????

Quess not, but you sure looked at a lot of them....

 

I got a lot of help here on the Forum, plus the 'Net had that list I posted above. Bottom line is, it'll be better than stock
If the CC 501 or 502 required addional mods, I may have not paid too much attention to them, should I have?
