Great street cam for SBC

I have had this cam on my shelf for the last 10 years waiting to put it in my 70 Vette I am restoring. It is in, sounds mean, idles very nicely, low speed is smooth on power and when you open it up it rocks. Timing wise it is a LT4 SBC cam if you 1.6/1 rockers.. I am using 1.5/1 so I am settling for the .500 lift in the old block. I would recommend this cam as a great street cam that actually works in city traffic too. Be prepared it sounds like a big block for real. ...read more

great cam ,with the right parts ,makes about 450 HP in a 383 stroker Chev V8 . Also I,m sure it,s the largest cam you can run with an Automatic trans with a stock torque convertor .
