Norris 301 Cam Questions (long)

I have a chance to pick a NOS Norris 301 cam. My 1974 2002 has a Pertronix/MSD/Blue Coil, a Weber DFAV 40/40, and a soon to be installed TII exhaust manifold. Would this cam be a good match, or is it too much cam for a daily driver ? I see that Norris is still in business, mostly doing Small Block Chevy cams. Does anyone know anything about Norris, pro or con ? Any ideas on the HP increase if I decide to have it installed ? TIA!!!

The idle was really not too bad with that cam. Low end power was ok, it wasn't really too bad for street use. I haven't degreed mine or anything, but I can say it feels less aggressive than a 292 schrick, so I have my doubts as to how numericaly accurate the "301" rating is. They are definitely regrinds though, the lobe base circle is even with the rest of the shaft.

Regrinds usually have some where around stock lift so they try

and make performance with enhanced duration cause if you can't

open the valve farther then open it longer.. this works to a point..

going schrick is really the way to go.. party on

I had one of these in my tii for a number of years and liked it for both street and track. Idle somewhat lumpy but not bad. Made power at 4000 rpm and up, will benefit from higher compression ratios. It had some effect with 9.0:1, and came alive with 9.5:1 pistons. With the 9.5:1's I dynoed at 126 hp at the rear wheels on the tii. (No porting or electronic ignition, just the cam and pistons.) I have the cam specs somewhere, have been told it is more like a Schrick 285. Lash caps are required. If you have the money, or really want a true 301 cam, schrick is the way to go. However, the Norris 301 is a fine cam for low-cost HP improvement.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
