Anyone know what the setup on this car was? Street port header and "modded intake"?

 

I ran a 15.3 with a 12a. The car had been sitting in the woods for years. I now have its drivetrain in my SA, but with a lot changed.

When it ran the 15.3 here are the specs:

stock port 12a with 64,*** miles
full RE exhaust
RE intake set up with weber 48 IDF
RB light weight steel flywheel and clutch
RB wires
no emissions
open diff crappy tires
timing was 180* off and caused the car to cut out after the first run (the 15.3 run)
bogging off line, carb needed to be adjusted
could have used some tuning and a tune up

 

Street port, comma, header and open exhaust, comma, '83 intake manifold converted to 4 independent runners, which kinda hurt power but I was learning.

Later, I cut channels in the manifold to make it look like a '79-80 manifold and ran a 15.4 at 87 (I think, fairly sure, it's been a while) with a stockport 12A in a heavier car through a fairly quiet exhaust.

The '80 was heavily restricted by the stock carburetor, BTW. Get a RB Holley setup. The RB carb is well set up (DO NOT USE STANDARD HOLLEYS) and the manifold is a nice piece.

The other car didn't rev high enough for the carburetor to pose a problem
