Since 2007 I have been sitting on a used engine that I pulled from a rolled over 95 Mx6 V6 MTX, the car had over 200k miles on it but the engine ran strong. Over the years 2007-2019 I have scavenged and sold parts off this engine never having any intended purpose for the engine. I have always figured if I blown the engine in the Turbo Mx6, this engine could be a quick fix for it..but not a reliable fix with the high mileage. But in 2020 I still have the basics of a short block left of it making it a perfect candidate for a engine build.
When the opportunity to get in on a bulk buy for Forged Connecting rods came up during spring of 2020, I decided to join in on it and build an engine over the duration of of winter 2020-2021.
The goal for this engine build is to reduce the compression a bit from stock, and have stronger internal parts. Everything else on the engine, such as valve-train, cams, oil pump, etc will remain stock.
After receiving the forged KAI connecting rods, I began buying all the parts needed to rebuild this spare engine.
Initially I planned on re-using the cylinder heads from the spare engine, but I found damage on a cam journal on the front head. I had also used this front head as a mock up for fabricating coil pack mount brackets. The mating surface of the head had suffered some deep gouges during all the handling of it when fabricating parts.
Additionally I did not want to invest the time into cleaning all the valves and valve seats. So I opted for OEM ford cylinder heads that I found on eBay for a reasonable price. These heads didn’t come with valves, so I bought those separately.
