Re: 91 4.3l

High Output uses CMPFI central muti-port fuel injection-a 61 psi fuel pressure requirement- recognizable by the intake manifold and air cleaner set-up- the standard uses a throttle body- lower fuel pressure and air cleaner right on top of engine --- after '93 all M-vans were high output......a much better set-up.....
