What I'm talking about is finding someone who is very experienced with making the Jim's 131 crate engine all it can be. Like switching to gear-driven cams, making certain the crank is absolutely true, experienced with which lifters are most reliable in this engine, which roller rockers hold up in this engine, which cams are the best for the type of power I'm looking for, etc.
I have googled quite a lot already, and about the only good recommendation I can find out there so far is Latus Motors in Oregon. I have also found a number of posts saying the Jim's cranks often have excessive run-out, and that the lifters that come with the Jim's engines don't hold up. And all Jim's engines come with chain-driven cams. I am trying to find someone very reputable who really knows their stuff regarding this particular engine and who has done many builds of this engine over time and who KNOWS and that I can TRUST.
