The dyno printout should show the whole run, so the actual “peak” may not have actually occurred at 5300(but..... then again, it may have).

I don’t recall all the details of the conversation he and I had about the power expectations when we were discussing the cam choice....... but I think it basically did what was expected.

With the 6bbl, the numbers are within 7hp from 5200-5900.


Yes Dwayne, i will get that sheet from the shop, but i don’t think it will be for a few weeks. I will send it your way and try to post it on here whenni get it.
And as far as our conversation, i think the cam choice was perfect for the intended usage. We knew it would never be raced at track. And his converter is not matched with a high horsepower build. So, you tried to keep it very streetable for power brakes and torque production from lower down. He thinks his converter is around 2500-2800. The sixpack was also a given from day 1. I am extremely pleased with the cam choice.
