ok heres the plan, my 89 GMC suburban and this little GMC commuter truck have the same engine, 5.7l TBIs. the one in the sub goes through 1.5qts of 15-40 a week. the C1500 doesnot go through any oil. the suburban is cool and fun to drive, the C1500 is not. so im thinkin i can drive this C1500 back to vegas and swap engines, and drive my sub back to phx. the bell housing bolt pattern is the same, the motor mounts are the same i think. the differences are the pickup has a 700r4 and the sub has a th400. i kno the pattern is the same, but wat about the TBI units, dealing with the TV cable and all?
