Budget Bird – PHR June 1987
This article is from the June 1987 Popular Hot Rodding that shows a bolt-on parts impact on a (new) 1987 LG4 Firebird Formula. The article shows the impact in both power (RWHP) and also the 1/4 mile performance of Edelbrock tubular headers, 3″ cat, stock TPI exhaust, Performer 3701 EGR intake manifold, and a custom cold air kit. The car picked up 48 hp at 4500rpm and gave a 1/4 mile performance of -1.28s and added 8.4mph!

Hot Rod ran this article on the introduction of Street Legal Performance’s (SLP) product line for the TPI powered F-Bodies. Note this article was run in mid 1988 when no one was digging into the TPI motors to make more power.
Quick rundown – with the SLP parts (runners, headers, PROM, exhaust, and cold air intake), power on a 1988 L98 F-Body went up 16lb-ft of TQ at 3600rpm (321 vs 305) and 21hp at 4400rpm (245 vs 224) and increased the hp gain from peak to redline by 50hp! (238 vs 188). The test car ran 14.93 at 93.45mph stock and 14.09 at 99.44mph with the SLP package and the optional oil pan – a decrease of 0.84s and a trap speed increase of 5.99mph. The car also picked up 2.1mpg.
