nothing wrong with the 110+2, it will just lope a little harder other then that you wont ever notice. The tight lsa will make a broad power band and make the engine feel snapy

he said it would be better for my application and that was with a bigger converter
also he said 243s with a valve job would be better for me than a ported head

I dont see how just a 243 with a valve job would do better then a ported head, 243 is a damm good head but its better when its ported, havent seen a single guy lose hp or tq anywere below most stall speeds they just seem to gain power everywere. dont think you would go wrong with a ported head.

Get to work then.. I don't see why a good ported head wouldn't help though.. I figure them prc 2.5s would make a heck of a difference

At least just grind out the rocker bolt boss from the runner, that alone will free up some flow and you really cant go wrong with that.

Geoff is very knowledgeable and knows his stuff. He does not like spec'ing bigger cams for trucks, and with good reason.

runner volume on a ported head is to big for a 5.3
basically the air would stop flow and lose speed because of size when the valve would close is how explained it
said it wasnt worth the price when a 243 head with valve job would be equal in performance

Considering i went from a V6, to this. I haven't had time for dyno/track numbers yet. Just a few mexico runs. Im not complaining one bit. You'll like the eps cam. Do some searching on ls1tech. Those guys are putting great power and times with small-mild cams. Plus the eps lobes supposedly aren't as hard on the valvetrain.

Hope that helps

Any dyno numbers or idle clips with this cam?
