Speedway cams are made by Elgin. You can call them for a recommendation. I don't recommend them at all for your combo of part's. You really need more compression to take advantage or the timing point's. At least 11.5:1 and you can regain what you will lose at the bottom end with 106 LSA. If you run the cam style, I would get the #02 cam. Just know that you might be leaving power on the table.

go to a JRM 108 or 107 cam, don't even look at the speedway cams. If you really want to go fast then get yourself a Camcraft.

wow that calls a behind the barn discussion u know what i mean . anyway i understand your money situation i build for locals here. i really do see the difference in budget parts. with a cam grind like those u will lose a large amount of holeshot. u said 600 rear gear (how long is track) what intake r u running and carburator hopefully not alky with 9to1 budget motor

It's interesting that the majority of you guys seem to think he'll automatically lose power with any of the Speedway cams.

Last season, I stuck one in a motor in a pinch (#15001) after blowing our primary motor with the isky cam in it. Our motor combo is a little different than the one in this post (11.5 compression, camel humps, marine intake, 4412 carb).

The Speedway cam made as much power or more than the isky for half the price. We liked it so well, we put one in our primary motor this year. Trust me, we're not down on power with it at all.

I'm not saying that it will work with his combo, because I do think that their cams are designed for higher compression. However, they aren't bad cams for the money.

The engine doesn't care about brand names. Timing event's are it's only concern. If you got them right, you got a good cam.

Almost all manufactures will fudge the duration and lift no. to protect thier customers from over camming a engine. It's prevent's Joe Blow from being unhappy with the power output because he over cammed and blamed the manufacturer for the poor performance.

you also must realize that these shelf cams (Midwest Motorsports, JR Motorsports, Speedway) Have been produced for numbers of years. I ran a JRM 108 Last year and liked it, but you can only go so fast on a shelf cam. I'd consider the JRM 108 over the 107, but the option is yours. If you want to make power, don't skimp on your camshaft/heads/intake/carb combo. In cowboys case, i'd go with the JRM Cam if your limited on budget. When you get some money saved up for another good motor you can make sure and get a good custom grind camshaft made specifically for your application.

For your B-Mod I don't recommend those Speedway cams, just too much duration for your application. For the money I do like the PRC 105 cam from JR Motorsports and the E1133 from Elgin. Many feature wins in hobby stock with the Elgin cam. If you run stock rockers, stay away from tight lash camshafts.

I ran a 14102 speedway cam for years in 3 different motors and all proformed well. Now i run a Howard's cam and it outproforms any i had up to the custom grinds from Reed.
