**blackout5.3** · 07-14-2009, 02:35 PM

What sort of numbers will the Gm Performance Hot Cam expect to bring?

Intake Duration at 050 inch Lift 219
Exhaust Duration at 050 inch Lift 228
Duration at 050 inch Lift 219 int./228 exh.
Intake Valve Lift with Factory Rocker Arm Ratio 0.525 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio 0.525 in.
Valve Lift with Factory Rocker Arm Ratio 0.525 int./0.525 exh. lift
Lobe Separation (degrees) 112

and will it have a lope? sorry to ask this if its been asked before but cams i know nothing about.

With a 112, it will lope some. Obviously your looking into a cam that drive exactly like stock or you wouldnt even consider doing all that work for a Hot cam. I would say a 224/224 or better yet, a 228 would be better. Thats just me, call Cam Motion or COMP and talk to them.

Looked into this quite a bit. Supposedly you can use your stock converter etc.
It does sound very mean but im sure a custom grind cam could yield you better results IMO.

For GM cams I've always liked the ASA 226/236 .525/.525 110 LSA.
A bit more powerfull then the Hotcam with a nice choppy Idle and also easy on valvesprings.

Hell, you could run a nice Yellow spring with these cams.

Not a fan of GM cams, But Thats just me.

**Hi-Po** · 07-14-2009, 04:50 PM

110 LSA will do that. Myself, Got a 114 LSA with a 110 ICL and a nice 4" E cut out.

Same affect.

thanks,

an to the OP i would DEF go with the ASA. drivability isnt bad at all, especially after a good tune and gettin used to it.

best of all i got 28 mpg on the highway through 4.10's comin home from the tuner

On the other side of the spectrum, for us a4 guys, on most sites it says you can run these with a stock converter and be fine. Probably a 22-2600 stall would be better because of the tendancy to push through the brakes.

**blackout5.3** · 07-14-2009, 04:59 PM

well im going to use a hughes 2000 stall and not using a pcm its going to be transplanted into a 79 t/a

Sweet! I need to get pictures of our 79.

Going carbed so you can use the shaker?

Should be a good cam for that project though
(off topic)

**blackout5.3** · 07-14-2009, 05:04 PM

keeping the fuel injection actually, i been trying to figure out a way to mount the shaker, i will have to get it shoved down in it first then think about it a bit and go from there

+1 Just installed one of these

Cam install is just too much work for a small GM hotcam. You'll probably wish you went bigger.

**blackout5.3** · 07-14-2009, 05:46 PM

so what other mods am i going to need with the springs and valves if i run the 228R

or would this be plenty http://www.texas-speed.com/shop/item...d=174&catid=49

Pretty much all you need.

Although depending on mileage, I would look into an LS2 timing chain and upgraded oil pump.
Also verify you will be getting the new batch of COMP 918 valvesprings.
