I run thru an air filter and mufflers. Of course my "mufflers" are 4" bullets. If you can call those mufflers. It only stalls that high in high gear,I wish it was a tad looser. It really starts pulling at about 5000 rpm. I think my motor is over-cammed for the compression it has. I'll get my cam specs up when I find them. The lift is in the high 700" range and the duration is really probably too much for my comp ratio. Aah,the joys of buying other peoples take outs
Its a lunati cam. pretty sure the part # is 50210. But Ill find out and get back.
