from a 228R to a 230/236
Well I did a search in this area and dyno comparison area...found some but not what I'm really looking for.
I am not happy with the outcome of my setup so it's time to switch something (best bang for the buck now) and that will be the cam. I have a 228R cam and been thinking of something bigger but not much. It's my DD and I still need some street manors and the 228R is just fine for that so I think I can stand something with a lil less DD manors. Here are my current mods.
01 SS 6sp
FFHP forged LS6 347
LS6 heads w/ bowl work & valve job (stage .5)
Kooks LTs, cats, custom bullet catback OTA
P/P TB, lid
UD pulley
fuel system to support 650hp+
valvetrain to support 620 lift
I make 402/376...I'd like to make 425/400 if possible with a slightly bigger cam. I still feel I'm missing 10hp with my current cam but oh well. I will switch to a 90/90 and EWP when "bang for the buck" doesn't matter so much.
I did a search for the comp cams 230/236...I've also been eyeing Livernoise 232/232 cam.
I'd like some imput from the cam guys, the guys who know thier **** about these motors...maybe u can figure out why I'm only makin 400hp lol.

Well I am by no means an expert and even have some questions of my own, but from what I see, you may have more to gain in the head department. Perhaps having your heads ported to increase the flow and milled to bring the compression up would net you the gains you want.

I don't want more compression because I want to run on 91 octane, I'm already at 11.0 to 1. I already have everything for a 150 dry but I'm switching to the halo. I didn't say anything about the nitrous at first because I didn't want those people that would tell me "just spray it, that'll get ya more hp"......no ****.
I have considered getting more head work done but like I said this is my DD so changing a cam is more efficient, I don't have to wait on anyone but me to get it done.

Your running the 228R and need more? LMAO Step it up to a Torquer 2 or 3? Hvae read many goo dthings about these cams, but I think with the Torquer 3 it requires double springs......do a search and you shall see.....

the t2 will probably get you to 415-420 but the tq you have seems alittle low.your numbers does seem alittle on the low side.to get more hp and tq you will either need a more agressive setup like a 228/232 on a 110 with maybe a * or 2 built in to optimize your dcr . a set of afr 205,tea 215 or any good head with a small runner should get you what you are after with a good scr/dcr.the heads may be the culprit but to get more tq and hp you will need your setup running maximized.

Where in the power band do you want to add more power? If it is the low end that seems lacking then a bigger cam will only make it worse. I'd do a quick calculation to see where your dcr is at. If it is low then a more properly matched cam or heads can help bring it up.
I guess there is also a chance that your heads were cleaned up improperly and they are actually hurting your numbers, do you have the stockers to see how you do with them?
Since you want a good DD still, I'd suggest a great set of heads over a larger cam. You'll get power everywhere and the idle won't suffer.

thanks for the cam suggestions but I don't want a 110lsa or a T2 or 3...too big for me. if I want higher #s (I'm only looking for 25hp) then I'll just spray it.

Last week I put down 425/ 400 on the 228. My graph is on here somewhere. The tune is off and I can get more out of it.
I do have a T2 112 sitting in the box on my work bench and im thinking of that cam, maybe the 230/236. Id really like the next cam to be my 3rd and last

may i ask how you installed the cam? i mean, did it have any advance ground in? did you advance it after install?
thanks, man.

Also, the 228/228 on a 110 LSA is still going to be more streetable than a 230/236 on a 112, because it will have less overlap, and overlap is what kills drivability.
If you want 25rwhp, listen to some of the guys in this thread. Milling your heads and/or running a little advance in your cam (timing gear for adjustment) will help bring that DCR up nicely - that will give you a bump in power everywhere in your powerband while actually giving you better part-throttle response and low speed drivability.
You could probably even send in your heads to TSP or TEA for porting, or maybe use them as a core charge, and get a new set of heads in just a couple of days for about the same as what a local guy will charge you. I think right now, it's about $300 to $350 for stage 1 porting of your heads. The downtime sucks, but it's a good bang for your buck upgrade since you already have a decent cam. Just degree the cam to set the valve events where you want them to optimize it for your configuration. An adjustable cam sprocket is also fairly cheap at about $40-50.
Remember, it's the little things that add up to give you a lot of power. With an EWP and ported FAST 90/90, you're looking at a 30rwhp increase. Put a set of PRC Stage 1 LS6 Heads milled down for added compression and a Cometic .045" gasket, and you're looking at maybe another 40rwhp over what you have now (especially if the work done somehow screwed up the heads). Degree the cam to get the DCR up and you could see another 10rwhp. Ricer math shows me that's a 80rwhp gain, meaning you'd probably hit 450rwhp without much trouble.
Also, 11:1 CR means nothing as long as you keep your DCR down around 8.3:1 for the 91 octane. And about the nitrous, configure your car to run without it NA and then tune it safely for nitrous.
