whats the next best thing after the CheaTR cams? after researching smog legal cams(pass sniffer) I finally decided that a CheaTR cams is what will meet my needs.
Only to find out that they are out of business.
what are you guys take on my options.
Id like to do 243 heads w/ ls6 intake and looking for a cam to match.

Technically our 224R cam on a 114°LSA (224/224 .581/.581 114° LSA) should pass California emissions. That's the biggest cam that I would sell you. Feel free to give us a call. We would be happy to help guide you in the direction you are wanting to go.

Id much rather spend that on combination of suspension mods and power mods.
Id imagine with 243 w/ cams and bolt on ill be around 400whp.
however procharger may be in teh future plans but thats after an engine build up.

im a bit familiar with it. but isnt the ls1(full stock) safer around 450 -500?
500-550 is pushing it correct?
so yes it may be in the realm but im also looking for reliability. I need this running rain or shine.
I also have the 98 w/ the crappy 806 heads so that number may be lower than other ls1.
not arguing simpleness or anything else. just the cost is way too high for what i want to run reliably. unless im mistaken on limits of stock ls1

I'd run it all day at 10-12 PSI on a stock shortblock. It's all about the tune. Otherwise, as long as you aren't in the gas, it would be more reliable than a heads/cam setup due to the stock cam/valve springs/etc that are designed for reliability. Remember, an aggressive cam is aggressive at idle too. The procharger isn't doing anything but adding a bit of parasitic loss.

FYI, If you're stock exhaust manifolds/shorty headers you need a split pattern cam with at least a 8* I/E split, with LT headers a single pattern cam like a 224/224 115lsa is fine, Unless you super charge the engine then you'll still want a split pattern cam, and I'd still go with at least a 8* I/E split.
For a split pattern cam I'd run a 218/228 115lsa+3(IVC 41 with -7* overlap) with your untouched factory heads, or a 218/226 114lsa+2 (IVC 41 with -6* overlap) which I'd run with ported factory heads, or aftermarket heads.
Furthermore since even a SC engine will benefit from a cam swap, I'd still do a cam swap first; it's still worth it!
As far as the heads just have your factory heads CNC ported because you can still fail visual inspection if the gm heads on your engine weren't available for the 98 engine. Your other option is aftermarket heads that are CARB certified, but then you're looking at spending over $2000 on heads them.

This would be a good CheaTR type cam that will work with manifolds and pass smog.

IMO, if he decides to go with a 214*(@.05") Intake lobe he doesn't really need such a wide split. A 226*(@.05") exhaust lobe would be more than enough, and then he could easily run a 114lsa and pass smog with -8* overlap (214/226 114lsa +0) and it'll have a IVC of 41, and there's still other shelf cam option available.
