But you and cheverlade have 6 speeds! The fall off with the 4speed sux cause I have to spin the cam past peak #'s so the shift drop isn't so bad(down to 3900rpm) until I got shift points moved to 6700 then it drops to 4250rpm BUT I've lost 30-35 rwhp from 6250rpm to 6700! No doubt this cam would be better suited in a 6 speed truck but even still stop pulling so early sux! All that being said the cam is a beast from 3700-6250rpm some people even thought I was spraying the truck cause it hit so hard( which I like) but wish it would make power till 6800 or so!!

I think the big dur. Splits on l92 heads make alot of sence due to port volume and valve size. I've talked to Roger @ Vinci and he spec'd me a cam that I like and made alot of sence and will pull to the moon! I think with this cam and 6 speed swap to come will make up on bottom end! Thanx for all the input guys!! I will let y'all know what I do and the results! Might even do a thread on it
