Do you have emissions where you live and did this make a difference? Did you
keep the stock manifold? Doesn't sound like it would necessarily changes
things that much as far as emissions go. Pugs 756

Subject: Re: Cams
Terry replaced my cam when I had the engine (AMC 360) rebuilt last winter.
This car is mainly for show, not racing or high perf driving. I went along
with his recommendation to swap cams since I do drive the car to meets and
generally try not to waste any time getting there :-) Here are the specs:
Competition Cams part # 10-200-4 grind number A 252H-10
at 106 intake center line
206 duration at .050
.2706 lobe lift
110 lobe separation
According to Motion Software Desktop Dyno, the calculated horsepower/torque
with stock vs replacement cam with 600 cfm single plane intake, stock
manifolds and mufflers is:
rpm stock replacement
2000 rpm 113/296 120/315
2500 rpm 146/307 158/333
3000 rpm 184/322 201/352
3500 rpm 211/317 233/349
4000 rpm 225/296 256/337
4500 rpm 222/259 266/310
5000 rpm 202/212 256/268
5500 rpm 174/166 232/222
6000 rpm 132/115 198/173
....etc...
These are calculated not actual dyno numbers. However, they illustrate a
rough comparison of the two different cams (c.p.). The exhaust is stock and
there are no major modifications to the engine other than a Holley 600cfm
4-bbl carburettor. The new cam does make a noticeable difference, and I
have
been satisfied with it. The cam and lifter set was was relatively cheap,
about $225 from Summit.
