Cam timing

[73Scamp]

Hi,

I have a question about the installed centerline for the Comp 282 Solid cam (pn 20-247-4) for my engine.

I have a .030 over Mopar 318 in a '73 Plymouth Scamp. The car weighs in at 3400 lbs and is street/strip. It is topped off with thoroughly ported iron heads, 1.6 rockers, headers, a Victor 340 single plane intake, and 750 DP Holley HP. It runs a bit over 10.5:1 compression and has an all forged bottom end with no problems spinning to 7000 RPM. The engine is backed by a Torqueflite auto with a 3500 stall converter, 3.91 gears, and 26" DOT slicks.

I originally installed this cam at 110 centerline and it is very lazy on the bottom end. The combo will typically pull about a 2.0 60-ft time and just seems very slow.

I've decided to dig into the engine and advance the cam to the 106 centerline that is recommended on the card. I'm wondering what I should set this cam at for installed centerline. The cam card states that it should be at 106, but I'm wondering if I should be looking for more or less advance on the installed centerline.

Thanks!
Gabe

i would move it to the 106 centerline, as it is the best compromise between maintaining the top end pull of the cam but still giving you the bottom end grunt you are looking for.
