I am puting a 305 in my 89 K5 Blazer and need the wiring for a 305 as
the old wiring wase junk can any one help me out ?????

Computer harness - '87 Chevy/GMC Pick-Up Small Block
'87-'91 Chevy/GMC Suburban Small Block
'87-'91 Chevy/GMC Blazer/Jimmy Small Block

You will need the PROM from the 305, and possibly the computer if the last 4
digits are different.

Engine Harness - '81-'87 Chevy/GMC Pick-Up Small Block
'81-'89 Chevy/GMC Suburban Small Block
'81-'89 Chevy/GMC Blazer/Jimmy Small Block

Either '90 or '91 went to the tiny headlights so the connectors will be
different.
