I just ordered my roller 230/236 cam and I'm having second thoughts that maybe its to big. I need to pass emmisions. Heads are 190AFR, ported superram,and Accel DFI.
Anyone running this cam? Thanks

 

Nope, I don't believe it will, but stranger things have happened.

A 218/224 probably will and a 224/230 just might if everything is "right on", but a 230/236 is a bit too big for the sniffer unless you ordered it on very wide lobe centers, like 114 or 116.

Even with the wide centers I don't think it will pass. The cam grinder should be able to tell you for sure.

Someone may know some tricks that may help though. There's gotta be a workaround.

That's a pretty stout cam, but should work very well in the 406. Traxion has a 230/245 cam on a 113 LSA in his 350 and was able to pass emissions recently with his dual cats and a little PROM-burning trickery. If you get this cam on a 114 LSA, you'll have no problems passing emissions in your 406. I know guys with 224/230, 224/236, and 230/236 cams in 350 engines that have passed the treadmill test.

I used that cam in my 383 until this year when I went to a solid roller. I had the cam ground on a 112 lsa and 4 degs advance. Last year the car passed an IM 240 emissions test without a problem. The idle was very stable and the motor made good power with that cam.
Your motor has some similarities to mine, cam, AFR190 heads, DFI etc.

I had that cam in my 406 with a mini ram and it worked out good. I dont know if it will pass emissions but I think you can make it work to your advantage using the DFI.

Mine was on a 114 with +4 degrees in it as well.

Thanks for the posts guys. My cam has the 112lsa. Can anyone estimate the hp for me?

 

Mine made 385hp at the rear wheels with the initial tuning. I believe with the refined tuning that was done the rear wheel hp was closer to 390-395hp.

The guy I'm buying the cam from said it would make 450hp easily. So I guess I could use my 24# injectors? Thanks again

 

I bought HiTech5's cam. It's still sitting in the basement next to about $3K worth of parts.

I'm doing a minirammed 385 with all forged internals, internally balanced. AFR195's (which I have not yet bought) with race porting. EA Pro puts the simulation at 510 HP at 6500 RPM, given a published set of modified AFR flow numbers and a 10.6:1 compression ratio. Torque hits at an estimated 4000 RPM and is predicted at an estimated 430 ft.lbs or so...

I'll be installing on a 110 degree intake centerline.

BTW, How did that solid roller cam work out?

WS6Transam - The Solid Roller is pretty impressive. It has a sharper torque peak than the Hyd Roller and after 5800, the motor flies to 7000rpm. I'm a little concerned with the longevity of the shortblock spinning that much rpm though.
