Your sig says 4.1 production block. If that's the case, a Melling 20IS2 will fit the stock 14 bolt pan. Summit stocks them. If it's a stage II, try TA Performance.
I can't find any numbers or info on the pickup mounted on mine. Mine is for a deep pan. It came with an engine that I bought already built. I would call TAPerformance or Nick Micale and see if they have dealt with a 0016 pickup. I may switch to an external pan pickup, but haven't decided yet. Here's some pics to give you ideas if you want to build it. Let me know if you want anymore details.
Thanks, Rob
TA Performance has the flange TAV1520F to build a pickup like the photo above, or TAV1520B for their aluminum block looks similar to the one above. I would call them to see if it will work with a stock pan. TAV1520C is for a deep pan.
