Re: How's this Crane cam compare to the LT-1
 

Mark;

Did you degree the cam in, or just install it "dot-to-dot"? Having the cam degreed in can make a very noticeable difference in when/where the powerband starts.

Since you've dropped your compression down to 9-1, you can probably get away with upping your intial and total timing as well, which should also help driveability. You might try something along the lines of 16° initial and 38°-40° total, all in by 3000 rpm since you have a stick and 4.10 gears.

Just thought.

I went dot to dot since I'm not racing it on the track. The old LT-1 rebuilt in '85 which got 43,000 mi was set by my builder dot to dot and it was still dot to dot when I took it all apart. Amazing.

I'll set my total timing to 36* @ 3000 rpm with dist vac disconnected. Haven't done that yet, got to swap the springs first while the heads are on the car. I only did #1 cyl so far. I really appreciate your replies too guys. https://www.yenko.net/ubbthreads/imag...iggthumpup.gif

For the rercord...I still have the orginal 11:1 stock pistons in my 70 Z with the Crane cam and it runs just fine on 93 octane pump gas. I do however add Max Lead to the gas which puts the lead back in the gas, and also raises the octane level to around 100 or 101. I found a place to buy Max Lead for 45 bucks a gallon and 1 gallon usually lasts me the entire cruisin season. Anyone interested in usuing Max Lead can read about it and buy it here: http://www.maxlead2000.com/

ah,the max lead 2000;just what i was looking for;building a 11;0 compression or more 396 and wasn;t sure how i would drive the car much ;with racing gas prices.I will try it out.thanks,chris
