Best cam for the street both power & sound
Best cam for the street........
Any help is much appreciated!
As to the cam;
My alloy-headed, 367 street-combo had three cams in the first 4 years of operation..
292/292/108 @11.3Scr making ~175psi
270/276/110 @11.3 making over 190psi
270/276/110 @10.7 making about 182psi
276/286/110 @10.95, making about 177psi
the Quench varied from a high of 039 to a low of 028.
I ran 3.55s, for the most part. but up to 4.30s.
I ran the 2.66 trans for the most part, then the Overdrive, with a GVod, then a Commando still with the GVod.
I can tell you that I liked the
[email protected] the best; but it had hardly any cam-lope, cuz the overlap was comparatively small.
Some of the cam-lope comes from the overlap. Some from the carb-tune. Almost none from the Idle-Timing.
However, the strength of the lope is directly related to the escaping gas-pressure which at idle, is strongly affected by timing.
I have a 4-speed, so, to drive slowly, I gotta reduce the strength of the effective cylinder pressure at idle, else the engine starts to buck in-gear. The easiest way to do that is to retard the in-gear idle-timing; which kills the strength of the cam-lope, and the amount of power at idle. Thus, at 500rpm, I can get down to 3.7mph, with 3.55 gears, and parade there for as long as may be required.
This is less of a deal with an automatic, where the power-pulses get lost in a higher-than-stock-stall, convertor.
