Alright internet,
March performance, 1st sent us the wrong pully system packaged as the correct one. That really threw us off. Now it appears we have the correct pully system but the diagrams they sent are for the kit with A/C. Looked on March performance website for a schematic but no luck.
We have a blue print 5.7 350 for an 87 Chevy...
Hoping someone on can make our life just a tad easier and help to confirm how the instillation goes.

Contact March? They should be able to provide the correct diagram for the kit you bought. If not, that company has went WAY downhill in recent years.

I tried yesterday, the phone just rang and rang. It was during normal business hours but late in the day. They are closed on the weekend so I thought I would scrape the internet.
