Alumunim 58cc GM Heads
JE forged dished pistons
Forged Crank, internally balanced
Aluminum short water pump
Edelbrock Performer manifold
Holley 0-80457S (600cfm, vac secondary, electric choke)
GM HEI distributor with vac/mech advance)
Edelbrock headers with gutted out cat.
misc bits and pieces (double roller timing chain, HV oil pump, etc.)
THM700R4 with a manual valve body and a modified TCC to work without an ECM commanded lockup.
Only one driven accessory - the alternator. (I did the 1LE A/C delete, and switched to a manual steering box to loose the P/* pump.)
All this stuffed in a 1987 Vin "*" (2.8L) Sport Coupe chassis... in otherwords, super sleeper
Biggest mistake made thus far: I should have just went straight to a 502 BBC and been done with it.
I'm currently on day three of gutting out the interior. New carpet showed up today but I still need to get the wiring behind the dash cleaned up and the extra circuits removed.
