228r whats better hp for DD?
I've got a 228r for my rebuild project, I got it 6 mos ago but I've been reading about these rev split cams. I know the 228r will give me the smooth idle for a DD, but with sooo many other cams out now I thought best to look around before putting it in...
Everything is new, ls6 crank/rods/pistons, 243 patriot 2 heads and all the usual boltons.
My goal is nothing too loopy, my 228r is a 114lsa so I could go to 112. I'd also like nothing too high lift up to .600 is ok. RWHP is 410-420
Thx

I have the 228R on a 114. Although I dont use it as a daily,the car drives good enough that I could. Its got some lobe, but nothing stupid. A friend of mine has the same set up at me, but has 228R is on a 112 and you cant really tell the differance at idle. The funny part is, I put down about 7 more RWHP than he did on the same dyno on the same day about 20 minutes between his and my run. Honesty I dont think the LSA had much to do with that, but HP between cars with the same set ups can differ like that. Im just glad I was on the higher side lol

I would stick with the 228R if the car is going to be a DD. It will easily meet the power goal you have set. My car made 400rwhp cam only with the 228R.
Car drives great and has a nice lopey idle.
