The original owner of this unique 1975 Firebird Trans Am had one goal: to rule over everything else in town, including the ’74 T/A SD driven by the local Pontiac dealer’s son.

With that in mind, he took the Silver ‘Bird to Yenko Chevrolet, where Don and Frank advised him that an L88 427 CI big block would do the trick. The craftsmen at Yenko Chevrolet fabricated the engine mounts, power steering and starter brackets and other hardware to facilitate the conversion, and installed 4.10 gears to maximize the L88’s considerable effect.

The result is this all-powerful Yenko L88 Trans Am, the only one known to exist. With just 13,000 miles on the clock, it is as fresh and powerful as the day it was completed. In the best Yenko tradition, the car’s history is completely documented, including the full ownership trail, title copies, all Yenko receipts and records and a listing in the Pontiac Historical Society.

Not denigrating this car at all, because it is a cool car, but here is a classic example of how things get distorted over the years. QUOTE: &quot;The craftsmen at Yenko Chevrolet fabricated the engine mounts, power steering and starter brackets and other hardware to facilitate the conversion.&quot;

I put a 427 Chevy into a kid's 75 trans am back in 1980 (I had put a small block Chevy into his buddy's 240Z and Trans Am boy wanted to one up him). Didn't need to fabricate anything. Got engine stands for an early 2nd gen big block Camaro; measured, located and drilled holes in the Pontiac subframe. No &quot;starter bracket&quot; to fabricate. Just bolt up the starter and use the Chevy support bracket. As for power steering, we just used all Chevy bracketry from a junk yard. Had to relocate the batter (IIRC) and used Camaro tray. All factory parts. Install looked factory. Located all parts ahead of time and did the swap in one day. Could have even hooked up the A/C, but he didn't want it.

Still, a really cool car. Just don't believe there was any serious fabrication involved in the swap.

I bet according to Yenko they had to fabricate everything.

Lynn:

According to the original Yenko Chevrolet Work Order signed by Frank Yenko, they did the following:

Install L88 Engine
R&amp;R gas tank cutout neck for high test gas
Build distributor for engine
Fabricate motor mounts
Fabricate alternat and p.s. brackets
Fabricate accelerator linkage
Rewire alternator, starter and gauges
Install new oil pan and starter nose
Fabricate new gas line
Install 4.10 Gearset
Install Lakewood bell housint
Operational Checkup

This is how the receipt reads. There are also 3 receipts for parts and 1 signed by Don Yenko for the L88 Enagine

When you have work performed at a Chevrolet Dealership, even back in the day, they delineate what was done and charge you for it. I don't feel anything has been distorted over time. Everything stated in the listing is completely documented with the original Yenko paperwork. Ed

No matter what, that is one Bad-Azzz car. Imagine being the guy cruising around in an L88 powered 1975 Trans Am back then; now THAT is the epitome of &quot;cool&quot;

So, what happened with your Trans Am? I recorded the Mecum auction and watched everyday except for the tuesday that they added at the last moment. I was rally hoping to hear more about it and see it in action.
