With a 1998 Vortec engine, you can get about a 20 hp increase simply by streamlining the intake and exhaust, with no other modifications. Use a K&N or similar intake tube with a low-restriction filter and dual 2.5 inch exhaust with Flowmaster or similar low-restriction mufflers. An additional 10-20 hp can be gained with very little expense by adding an insert inside the intake tube that "spirals" the air. "Vortec" or "Cyclone" are two brands that manufacture these inserts. Putting a similar insert in the exhaust just behind the mufflers will help too, although the exhaust ones are harder to find. An interesting side note is that every one of these modifications also increase fuel economy. Large horsepower gains can be experienced with more in-depth mods like upgrading the camshaft (open valves higher and longer), heads (compression, valve size) and using forced induction (just another way of getting more air into the combustion chamber). All of these require computer reprogramming or upgraded chips, and fuel economy will not always increase, and may decrease.

Probably about 240 or close. Move to a 96 and it's a lot more. The Vortec started in 96 with the 350 (5.7) and 454 (7.4). I understand the Vortec 5.7 had a little more power than the non-Vortec 7.4, and the Vortec 5.7 has 250 horsepower.
