Cam opinions I am looking to install a cam over the winter and some 243 heads if I can find some here in the UK
I have bought a used cam and I want to know what people think this will be like for me n/a as I am of the understanding it's a blower cam
It's a cam motion 222 230 .576 .578 114 lsa 110 intake c/l
Car has headers and ory ls6 intake 3600 stall
I may spray in the future
Real question is will this work OK or should I buy another cam that's a proper n/a cam
If I didn't already have this I would probably be looking at something like a 228r

That cam should work fine on your setup. It's a little on the small side, but will be a huge gain over the stocker. If you're looking to get every bit of performance availible this isn't the perfect cam. If you're trying to ball on a budget...this will do you fine.
On a side note, all of that extra exhaust duration would love a little giggle gas

But in all seriousness, that isnt the tightest LSA ever, and should let the exhaust valve open a little later. Should carry fine into the upper revs. What do you realistically plan to spin this to?
Like i said before, for a ballin on a budget type of build, i'd slap that thing in there and enjoy the ride! if you end up deciding you want to go with a different cam, we can all start talking numbers!

I was thinking of shifting at 6500 max
You are dead right I need to just go with this and see how it runs if I can make 35 -40 more peak with plenty under the curve I will be happy car runs 12.4 now I am swapping out the 2.73s for 3.73 this week too and that and the cam should see 11s and then maybe a 10.90 on a 100 shot?

should work fine but with that stall it would not hurt to move up a couple clicks...something in the 226/230 or 228/232 range. However if you only want to shift at 6500rpm then stay with the 222 cam.

2 things make a cam act smaller, compression and displacement. The 243's will increase compression over the 241's stock vs stock. Milling the 243's will give even more. Forget about static compression and focus on getting your dynamic compression around 8.3-8.7 depending on fuel quality around you and how much you trust your tuner (or yourself if you're gonna be doing it)
This will make this little cam idle better and drive more like stock. It will also make more power on this cam, so there's no need to swap.
Picking up the 243's, especially if milled, will make a cam swap even more useful than before though.

Cometic = higher cost but better quench and a tad bit more compression. Beware that if you combine these with 243's that have .030 or more shaved off, you will possibly run into PTV issues and may need to fly cut your pistons.

If you have your old gaskets laying around, I would slap it together and clay the heads to see what ptv is at. Of you have room to spare, definitely run the thinner gasket. Not only will it increase compression, it will help with quench. A tighter quench will help fend off detonation and provide a better burn. With a smaller cam and less than .600 lift my bet would be that you're okay, but I would still check to be sure!

I wasn't thinking of going crazy with the mill because even with stock castings and gm mls gaskets dcr will be around about 8.3 due to early intake valve closing 016 off the heads and 040 gasket should put it in the 8.7 range so I was thinking 010 mill
although I will check I can't imagine having any ptv problems the cam has -2 overlap @.050
I was also thinking of retarding the cam a bit but I don't have an adjustable chain just the I iwis chain
Cam events installed dot to dot should be
Ivo 1
Ivc 41
Evo 53
Evc -3
I was thinking that it may work better na 2* retarded
It's hard work making the decisions on this sometimes I think I should just button it all up unmilled with gm mls gaskets cam dot to dot and see how it runs then I think if I am going to do it do it right and then I question keeping the cam or getting something else

Just updating this thread
Buttoned it all up over the winter had to order shorter pushrods
Ended up with 15 thou off the heads and gm mls gaskets
Well the little cam done good
Still sorting out the tune and shift points not pushed up yet and it went 11.70 @115.1 first trip to the track done more 11.7xs and on diferent days
I think with the tune nailed shift points up a bit it will go 11.5 in some good air
