when you said the wiring harness is intimidating ..well that is really profound.
time is a big factor. it takes time. for me i had to be by myself and think of a new harness at $300+ dollars. i used labels, diagrams, solder, butane, and plenty shrink wrap.
i have a '95 LT1 from a buick roadmaster with a soloman tune. and the van is a '87.
this is all need to RUN engine for OBD1.
VSS codes disabled. for the 700r4. another 95 4L60e trans is showing up here soon...there may be stalling coming up to a red right caused by no VSS. i dunno yet, and this may not happen. maybe idle screw tuning will help??
I am ready to sew mine up and start engine here really dang soon.
yet i am still baffled where i should place PCM.
i thought of replacing battery location and mounting PCM there.
i thought of replacing old ECM and fabricating a location there for the PCM.
ANY TIPS ON WHERE TO PUT PCM?
WHERE DID YOU LT1 OWNERS PUT YOUR PCM?
yes you will have to modify the frame using the non-corvette accessories/bracket for the a/c compressor. I got an a/c delete pulley for temporary. also i am going to have to customize another location for the ac dryer, cause i will probably keep the camaro/impala/buick style bracket on that side.
i have yet to buy a battery for the van. i got a single 16" 220 watt fan on ebay for $38. i bought a new starter cause engine came with out, for $52. i am using 700r4 (i will need aftermarket tcc lock up kit) and original radiator. egr block off plates on ebay, $12. i got a/c delete pulley on ebay for $38. later when more time and money is available i will get bracket for a/c and mount at the corvette style location. new melling 55HV. oil and consumables; less than $1000 for van and LT1.
time=priceless. about 2 weeks of gathering all i needed. about 2 weeks of hands on actual time involved. but i have been on this project longer.
exhaust will be simple true dual with out catalytic(s).
i have a problem with the heat shield on the LT1 factory manifold on left side of engine touching the floorboard. the slots in the JTR mounts are not jammed up yet and i think i can get engine over 3/8" - 1/2" and maybe trim there at the floor board where the doghouse cover comes up to meet.
i got lost in my wiring for it seemed perplexing to begin. it was time consuming. but it can be done. there is therapy in it. lol. and it is an education. but i have good news!! i did it so can you.
