I haven't found many references to the Mr. Gasket chips. Looking thru the old threads, 10-20-04 ecoman asked about a Stage 1 and Stage 2 chip. He got ZERO replies.
The only other modifications I found - descreened MAF, punched cat, and a set of turbo mufflers. The internals of the engine are unknown. It has been out before and now has a 1 piece rear main seal, which according to my information didn't come out until 86. The heads are cast iron. I haven't taken the time to pull the AC compressor off to get to the stamped I.D. numbers, so I have no idea of the origins of the block. The car seemed to run really rich, and had a history of failing emission tests. I replaced the Mr. Gasket chip with a Hypertech chip and it seems to run better. The fans come on at about the same temp. with both chips.
If you have access to a device programmer, you can read the bin from the Mr. Gasket chip, then compare it to a stock bin with something like Tunerpro. It'll do a byte-by-byte comparison and display the results.
Let me know if you have any Prominator questions...
geekinavette - as soon as this low tech guy can ask an intelligent question...
Edmond - I have been wrenching on my own cars for almost 30 years, so I will build it myself. Probably a 383, roller cam, and aftermarket heads. I love the look of the TPI so I will use big tube runners and intake. As for headers, I have thought about building a set of Tri-Y's. Some people feel the design is better in the mid-range than the four-into-one .... and didn't Hot Rod just put a set of Try-Y's on their project Solstice?
Show's will push anything, that's where their money comes from.
As far as headers go, the brand that get's some of the most positive reviews are the TPIS headers. They're not cheap but they are nice looking. Most say that fit and installation are quite easy. Since you've wrenched for 30 years, I don't see you having any problems with them. Can't say the same for me but then again, there was never a problem that a big or bigger hammer couldn't solve. :L:L:L
