Hey all

[DSMRon]

Hi guys i got a question.
I'm going to be rebuilding the engine real soon and i was wondering
what the best setup for the internals would be so a can to run a big 16g all day
prob around 16psi.
Now i heard a 1991 6bolt engine with bigger fuel pump and bigger injectors would prob run it all day now is that true.

A 6 bolt with stock internals will support a 16G just fine. Or, you could just rebuild your 7 bolt, both will be just fine with stock internals and a 16G...Especially with the 16lbs boost you're going to run.

You'll need upgraded injectors and fuel pump (Walbro 190lph), plus an SAFC/GMAFT or something of the sorts to run larger injectors. Assuming you know the rest of the stuff to buy.
