flow bench prep





some more progress...(not finished)



turns out setting up a build with off the shelf parts is not "good enough."

i will have more specific numbers when this is complete but so far on the rod bearings, the ACL HX is too loose in our eyes.

our goal on this build is as close to oem spec as possible...while producing 450whp.
oem spec is really kinda vast though...

That's been proven to be true already Jake, look in the cylinder head flow database. Any well ported USDM head can flow more than the biggest of the stock big port JDM heads. Unfortunately everyone who gets their heads ported doesn't get well ported heads. My first set off ported heads that I bought used they blew major ass. My current DPR heads are head and shoulders above the first set.
