true, about the crank. a t3/t4 could hold it. i ran 15psi on my stock ls w/ stock fuel injectors and an fmu and a t3 for a couple months. its capable. he just wants it to spool quick and blow big air. ur probably right on the injectors..... he should go higher but well see hes still not 100% on what hes gonna do. we still have the bare block on an engine stand. we'll just have to work out kinks. his block will be strong though.
