I am rebuilding a 4.0 for my 2000 Ranger and the local parts store wants $1150 for a rebuild kit including rocker , pushrods , pistons , rings , and the full gasket , etc. . A kid in my class told me about this website RPMmachine.com , i am kind of wary of it , since their kit is half the cost of the one from the parts store but does not include rockers or pushrods. Has anyone heard of this site before , or am i better off going with the local place ?
