Doing a rebuild due to a severely spun rod bearing. Looking to see if there are opinions on how much flow i could expect from a 22re head. I know the limitations lie with the fuel injection, so i guess is the 150hp range feasible with my engnbldr 268 cam and a good flowing head?

 

Define a good flowing head.....are you talking about 22re

Not much info out there LCE was supposed to have a page on porting but it was under construction forever, engineblder has a ported head $$, he gave me some advice- knife edged the swirl ramps- keep them though, gasket match, clean up the machining- to tell you the truth other than upsizing the valves I didn't do much- that said, I bought a new head off Ebay and even though it is offshore manufacture, the casting/machining quality was far better than the oem head it replaced 20 years of tech. I also ported and epoxied around the injectors.

 

These might be helpful.
