What to do? Been a memeber for a few years but have done more lurking than anything. I have been debating a cam swap for quite some time but I just cant decide whether to go the safe route 224/224 114 (which I have read is basically the largest cam you can run and still stay smog legal.) or go all out and just try and find a "good" smog shop. THis is the point where most people would ask what my goals are so I guess they would be to have a cam only car that would have all bolt ons and put down somewhere in the neighborhood of 350-365 hp with a nice idle
. I have a 98 Ls1 with pretty much stock drivetrain with the exception of a magnaflow catback and slp lid. I just dont know if its worth the hassle here in cali esspecially where I live in Pomona where the cops are dicks about modded out cars, and they know their ****. The only other option I could think of is to go the nitrous route. Oh and before I forget, this car isnt a daily driver it see's the street once ar twice a week mostly weekends. Any help is appreciated, hopefully it will help to sort-out my options.

A 100 shot will give you awesome power, more then a cam and boltons would. here is a link i made not too long ago hope it helps.

Best advice if you're looking at staying smog legal.
I also like this route given stock appearance/manners with power on tap, and also it's much cheaper than modding every little piece of your car.
If you go the full exhaust route (LTs, ORY, etc.) then you shouldn't worry about the cam since you're illegal anyway.

yes it will pass emissions no problem, i was going to go a small cam route before i did longtubes but i ran out of funds. with a small cam like the cheatr most cars will gain about 30rwhp or slightly more
Nevermind...go with a big cam

thanks for the quick responses. I think that I might go the small cam nitrous route. I figure that I'll do the cam first becasue I was going to change my timming chain and oil pump anyway. While were on the subject if anyone has any extra parts, or good used parts that they need to get rid of I could use them. Shoot me a pm and price. thanks again

will you really pass emissions with half ethonal?? i plan on getting a 226/232 custom cam pretty soon, would a smog shop know that my rear o2's are deleted?? and do u think i can pull it off by having a cat only on the I pipe if the guy does not do the visual test? sorry for the hijack
Shops do not care if your rear 02 sensors are deleted, mine are and I had no problem passing smog.
If you guys are worried about cops or passing smog with long tubes or a cam this is what you need to know. Long tubes are illegal in Calif because you are relocating the cats and by law we are not supposed to mess around with emmission stuff (ie. moving or taking off the cats).
If you want to run a bigger cam then stock the biggest you can run is a 224 with a 114 LSA to pass with flying colors, whichwill still give you good power. You can run a 112 LSA but without a really good tune you might run into some problems. Anything bigger then a 224 cam wont pass smog

I have thought about that 224 224 114 myself for years, I did the LS6 cam to just get me by 4 a while. The more power you throw at it though the more things you will have to replace..The rear-end is one thing I know will not last.
If you have over 500TQ. If he's shooting for the 360-365 Range, then he shouldnt have any problems with his rear end. Thats another thing to think about too. Getting a set of gears. You will suffer on fuel economy (a little) but your 0-60 time will go down.
We can calculate overlap and have a good idea if the cam will pass smog, but lope is subjective.
can you get that power with smog legal a boltons??
ill just do ported TB, ls6 intake
seems like you should do the ls6 intake first then go from there...
and see if you want more power just do cam on top of it all
and plus some nice gears

perry ford in san diego area has it but you should call around the chevy and ford dealerships. I am surprised more people dont know about it. It costs around the same price as gas aslo but it is a bigger molecule so it will make your car run leaner. So do it when you are at the very end of your tank and only add what you need.
