Well I made some changes to my 1986 coupe. First off I dropped in a 408 with some fully ported dart iron heads. Yep you read it correctly iron heads. I wanted these heads due to their stockish look. I also purchased a victor efi intake manifold that was ported along with the heads. The heads flow 303/232 @ .600 lift. Other items are a accufab 90mm tb and a meziere electric water pump,42lb injectors, pmas 95mm velocity air meter.
The exhaust consists of mac 1-3/4 long tubes with 3inch collectors going into a Dr. Gas 3 inch x-pipe. Finally a flowmaster 3 inch catback with the new super 44 mufflers. The car is loud and listening to it idle is sweet music to my ears. The cam is a custom hyd roller (250/260ish @ .050 .600 lift)
I had the car dynoed with the new combo and it made a best 464 hp and 450 tq SAE.
Later this year I plan on adding a tubular k-member and possibly doing more port work to the heads.
The car still drives good except for alittle bucking below 2000 rpms. But I can tell you this once you stomp the gas pedal its ridiculous. I still have a/c too and it blows cold. One other thing I added was some 10 inch wide prostars for the rear with a 6.5 back space. The wheels tuck in nicely and they look fat from the rear.
Anyway here are a few pics of the car:
