the cam is all done at about 62-6500rpm straight up. Retarding the cam 4-6 degrees will allow you to buzz it 7000-7200. The cam is a proven piece of art. Has a smooth idol when the engine warms up. it would work well on the street, and well on the strip. </div></div> That would be a killer for me. If it had a smooth idle no way would I have it. If you want a smooth idle , buy a new Mustang, just not a muscle car without it. |

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: XXXBlackLs6M22</div><div class="ubbcode-body">Another great camshaft that I have used on a couple of LS6 motors is the Lunati 20202 Camshaft.

Here is a video of my car idling in the garage with the sound of the Lunati 20202 camshaft. Puffing white smoke at the rear as it was -10 degrees outside on the winter day the video was taken. http://youtu.be/gY6TBYtok6o Exhaust is stock Manifolds with a 1969 Chevelle Chambered exhaust system. I chose not to install the rear resonators on the rear tail pipes so it has that nasty sound. The motor is idling at around 850 to 900 in this video. Rear end has 3:31 gears with M22 trans. My car fries the tires anytime I nail it [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Go with the crane version, the pure stock guys have done the research over the past 2+ decades now after trying everyone else's flavor yet the crane remains the gold standard. And I wouldnt worry too much about the gear, it idles fine and has plenty of beans down low, the converter is more important...that cam has gone deeeeep into the 11s through exhaust manifolds and on polyglass tires so it can't be too bad. </div></div> That is the sound I'd like at idle. How is the vacuum -- power brakes OK, etc.?

Sorry XXXBlackLs6M22 -- haven't figured out how to reply ... again, that is the sound I'd like at idle. How is the vacuum -- power brakes OK, etc.?

I'm sure the "1320 boys" will chime in on this...seems to me you would need a little more gear to get there...but, maybe with headers, good tune and traction it might work. The M20 will help the low end torque...wilma

Plenty of Vacuum for the Power disc brakes and everything else, if you look at the hood when I touch the gas pedal, even the cowl induction has very good vacuum. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

depends what you have for tires and exhaust.. if its a 10:1 bone Stock engine, with small tires and manifolds.. i would bet you will make 13:40's with 3:31 gears... IMO... Its hard to say!! we need more info on what you have for a set up. 3:31 is not a 1320ft friendly gear..

Re: LS-6 camshaft
I did say it was a 375hp. That is 11.0:1. It is "bone"stock. Non modified 840 heads,4346 Holley,stock exhaust with transverse muffler. F70x14 bias ply tires. I do have an xtra rear end that has 4.88s,but hesitant to change as it is a later date casting. 3.31 is original.Car has traction bars.

Re: LS-6 camshaft
if its a fully blue printed 375 hp 396, makng a honest 375-400hp at the fly. With the M20 and a set of 4:56. The car will have potential to do 12:20's @ 112-114mph. You ll need to get a 1.8-1.9 60ft time. And power shifting will be a must.
IMO the 4:88 will be too much gear for that motor. 4:56 will be the perfect 1320ft gear for your combo. I think anyway... Thats what we always run. Good luck!!
