Heavily Modded 3800SC 87 GT build Thread (Page 1/16)

I have owned my 87 GT since i was 14 years old and i decided that the 3800SC was a good place to start a build thread on my car. I bought my car 5 years ago as a bone stock 87 GT 5 spd. Below is a pic of what it looked like when i picked it up in Dayonta beach FL.

Me and my dad decided that we would completely rebuild it from the ground up.

On its way to the paint shop

After the paint

This is when it still had the stock 2.8 in it

This is when i decided that it was time for a engine swap so one year ago i started looking on carparts.com and i found a 3800SC close to me that had 45,000 miles on it. So i went and picked it up. The engine came with everything but the PCM and wiring harness. It came out of a 99 buick regal. So i tore the motor down and had the short block completely rebuilt with ARP fasteners throught and clevite 77 bearings. I also had the shop port and polish the heads. They flowbenched the heads and they came out equivelent to the ZZP Stage 3 heads. Here are the pics as of tonight what we have got done on the motor. There is a list of mods also.

Here are pics of the trunk while in progress of cutting the bottom out. We basically cut the back out and then folded the front section up into the trunk to make the flat floor all the way across now. More pics when i get it sealed up and re-carpeted.

do you have bigger valves for your ported heads.. if so what valves are you going with?

Friend of mine had the 130# springs with aftermarket valves and the valves failed.. creating all kinds of damage


Coming along excellent though.. I like the yellow

I remember back when your dad was explaining how you'd go piece by piece through the engine bay making it look brand new. That was really awesome how you and your dad worked on it together back then and now with the new engine its going to be even better! Great thread.

Damn sweet car!!

You say you are in California? What area? North or South? Are you still going to run the 5-speed? What process are you going to use to get it past the Smog Nazi's? Keep this thread going. I really enjoy the build-up...

Cordially,
Kevin
