with a cam of that size it would seem difficult to tell if you have any low end. a 3500 stall doesn't get you to the low end.
as for picking your cam Suddog, there are none that will give you good low end torque from a 293 cube short stroke engine. the stock converter isn't a high enough stall with the stock cam let alone going bigger. the comp 206/212 is probably in the area of your best shot at having any decent low end torque. something like naked av is running would also be what you're looking for. |

https://ls1tech.com/forums/showthrea...ration+lifters https://ls1tech.com/forums/showthrea...aft+discussion not sure if youve read these but they are good discussions that will answer your questions, just remember they are using those cams in a bigger 5.7 so it will lower the power band in comparison to a 4.8 but the principales are the same. About the converter thing, if you plan on getting a cam that creates alot of its power off idle or down low it makes no sense to get a high stall. The tcc is there to put you into the rpm range of a larger cam, so with one that creates off idle power you would be stalling right past some of the power band, less area under the curve. A big stall doesnt create power down low, matter of fact it will only multiply torque once near the stalling point. For what your looking to do I thing your on the right track in picking a cam and wont need a higher stall. Look at the specs on the stock cam, read the articles then put the two together and you'll have a picture of what cam you want. |
Yeah LOL. My fault I worded that way wrong. A Stall with get you a lot of power of the line is what I meant to say by jumping up the RPMS to where power is at it's greatest. Wow, I bet yall think I'm an idiot now ;)

i knew what you meant by it, but wanted to clarify it for others that may have taken it the wrong way.

i didnt get my truck dynoed with this cam,but i put in in , drove it for a couple of weeks and then i got a great deal on a bigger cam to go with my whipple.this cam was real stong on the bottom end,pulled hard to about 5500 rpm
|
Mine gave me 15 RWHP all over, 20 RWHP peak, on back-to-back dyno runs, with the cam being the only variable changed. This is the same cam.
Best part of the cam install was the off-idle power....'holy shit' :eek: is the best way to describe my reaction. I am very happy with it. |
Kim Allen, PM with a price please.
