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>
^ What he said. 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.?

If you want a smooth idle , buy a new Mustang, just not a muscle car without it.

ill take the smooth idol with a win over a lumpy slow cam.

I have a Federal Mogul 143 version. The price was right, but I have not installed it yet. Should I get the Crane? 375hp engine in 69 Camaro , M20,3.31 rear. Hoping for mid to low 12's. What do you think?

I'm sure the &quot;1320 boys&quot; 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

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..

Thats what i meant by &quot;bone stock&quot; usually a slapped together big block only came in at 10:1 or so from factory. 100% agreed still. Lucky to get out of the mid 13's if this is the case.

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.?

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]

I did say it was a 375hp. That is 11.0:1. It is &quot;bone&quot;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.
