Customer supplied 88 Formula with T-tops. He has to comply with emissions so I gave him the option of running the WCF headers so he could run both a cat and a muffler; or run just a cat with resonated tips, or cut out the trunk and run a cat and muffler using the stock manifolds. He opted for the latter because of a concern of loudness with resonated tips and he didn't want the WCF headers.
As described earlier, the engine is bone stock. The customer wanted as low-buck of swap as possible. Even so, I try to make new innovations with every swap I do. The customer wanted poly mounts, so I fabricated some on all 4 corners (which can be done when running an auto). Doing this meant he didn't need to run a dog bone at all, but he still requested it so I built a bracket for that that would work with the OE 3800 tensioner bracket. I also came up with a new low-mount alternator solution which I noted in another thread.
Another first was the use of approved Nylon fuel lines. That's right, the same thing the factory has been using since the early 90's. The line I used was SAE approved which I bought from a local NAPA. Installation is as easy as heating up the end and pressing it onto approved fittings. I must say it worked out nice and looks good -- certainly much better than rubber hose and clamps; safer too... NAPA also recommended stainless crimp-type clamps for this nylon line which I used also.
Everything is fabricated in-house except for the A/C lines. I have a very good local A/C shop that is more than happy to do the job at a reasonable price. I use new wire loom on every part of the wiring harness I custom make to the vehicle; and this isn't the cheap plastic crap you get at Zone that melts the first time you run the engine; this is the "green stripe" stuff GM uses that withstands higher temps.
This is the first time I have done one of these swaps in an 88 chassis. Since I custom built my mounts, I was able to lower the engine/trans as much as possible on the cradle, thus affording as much hood clearance as possible. The trans/oil pans sit AT the bottom plane of the 88 cradle.
Here are some pics:
If you have any questions about what parts were used or how/why I did something, I would be happy to answer them.
