My 1986 Firebird Trans Am
Home Up My 1986 Firebird Trans Am Helicopters

 

This car has been an ongoing project of mine for several years.  I rebuilt the engine several years back just to have my ex blow it up several months later.  Since then, I decided to build it strong.  I took out the blown up 305 and built an engine to the following specs:

Block:  4 bolt main Chevy small block, 383 stroker kit by Speed-o-Motive with KB Hypereutectic pistons.  All rotating mass balanced within 1/2 gram.  Block machined surfaces blueprinted.  All fasteners are ARP.  I did the block modifications to clear the stroker crank, and blueprinted the block.  Calculated compression is real close to 10.2:1.  

Heads: AFR aluminum, Crane gold billet roller rockers.

Induction: Accel TPI SuperRAM fuel injection

Exhaust: Edelbrock header/exhaust system, Hedman catalytic converter, Borla stainless cat-back system.

Ignition: So far I am using a stock chevy HEI distributor, with an Accel coil and graphite sparkplug wires.  The plugs are Bosch platinum's.  The distributor timing is controlled by the Accel EFI computer, and I have the kit to convert to the f-body style distributor (remote coil) but have not done so.

Miscellaneous: Edelbrock Victor aluminum water pump, GM Z-28 oil pan, windage tray and oil pressure spring

This engine has not been on a dyno yet, but I expect it produces 425-450 horsepower.

Transmission:  So far this is a stock 700r4.  I am weighing the idea of scrapping it for a T-350, but it has not let me down yet and I like the overdrive.  I will most likely do a performance build on it and treat it to a 2400 stall B&M Holeshot.  The Accel EFI computer controls the torque converter lockup, and I can set the RPM/engine load where the converter locks up. 

 

Interior

I have removed all carpeting and interior trim to apply sound deadening materials, similar to dynamat.  You can see the material applied on the drivers side of the car.
