Shnalla Posted November 22, 2012 Share Posted November 22, 2012 Hi buddies, I am questioning myself about camshaft... I got aluminum heads for my L48 small block and a nice Performer Air-Gap Intake. My goal is low end torque, from idle to 5000 rpm and keeping a decent mileage. Heads are 62cc (intake runner 170cc, exhaust 69cc and 2.020 / 1.60 valves). I Got true dual exhaust and stock converter. I wonder which cam fits the best my needs ? Quote Link to comment Share on other sites More sharing options...
gprimm Posted November 23, 2012 Share Posted November 23, 2012 I would suggest calling a cam manufacturer and you can give them your rear end gear, type of trans, etc. Otherwise, I have kind of the same set-up. 350, aluminum heads and I just put a 700r4 and 3.42 gears in it. Based on that I have a Comp Cams XE268. Idles nicely and the RPM goes to 5,800. Strong all the way around. Now, my son had an engine built by an engine builder and the builder loves Howard cams. It is a 350 also, and torque first then horsepower was the goal. The torque is close to 400 ft. lbs and the horsepower is about 330. Extremely effective cam. Howard Cams #112571. The engine is in a 78 Malibu Classic Wagon so the weight will be around the same as the Monte. He drag races it (14.2 seconds) and Autocrosses it and beats BMWs. I built the wagon and there is nothing stock left on it (drive train, suspension, etc), although it looks stock everywhere. Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted November 23, 2012 Share Posted November 23, 2012 I imagine that it would be tough calling cam manufacturers from France. I think that read that you have stock gears. Something along the lines of a comp XE262H would probably work well for you. Some people have had poor luck with flat tappet cams in recent years and prefer retrofit hydraulic roller cams. There is a little more expense but rollers last longer and seem to make more power. Quote Link to comment Share on other sites More sharing options...
gprimm Posted November 23, 2012 Share Posted November 23, 2012 Well, I should have said contact them. Since the time difference is 5 hours from there you can get them. They also have email or forms online and they'll get back to you. Comp Cams actually has a program you can download and put in the parameters that you have; weight, gear, head type, intake type, headers, stock exhaust manifolds, etc. They will give you an approximate HP and Torque results. This is based on their testing. Pretty good. I downloaded it to my hard drive. You can get responses online with their tech questionaire. If you have trouble, I can do some homework for you. When I called Comp CAms they recommended the XE272, so I stepped back. Going one lower wouldn't hurt at all. The Howard Cam my son has is very impressive.
