I have the gt40 explorer intake, not on truck yet. and i'm gonna port the ex side of my e7's. Out of these similar cams which is gonna give me the best torque in the lowest rpm range.

 

the 31 version is for a 302/5.0. while the other is for the 5.8. of course either can be used, just make sure the proper firing order is setup

 

That explains why the 31 came up during the normal search and i had to do a direct search to find the 35. thanks kemi,

btw, i'm USAF stationed in ga, but i'm from mid eastern oregon. hows the weather and fires seasons been doing back at home

 

we are having some pretty good Tstorms moving thru today/tomorrow, but so far the fire season has been behaving itself and has stayed under control. its hasnt been very hot yet or very dry. Hunt season should be real good this year
