Advertised: 1998 Trans Am = 305HP
1998 Trans Am WS6 = 325HP
The truth is any f-body LS1 should be rated at 345HP. GM under-rated that motor.
310 for the LS1, 325 for the Ram Air (WS6) models.
350s weren't in Trans Ams in 2001, but the 5.7 LS1 had 310 hp that year.
The base LS1 had 305 hp, Ram Air (WS6) models had 320.
The LS1 was not a 350... and what was your question again..?
you dont have a ls1 you have a lt1. the ls1 was in 98-02 camaro
in 1998 gm started putting the LS1 engine in the trans ams and z28, firehawk, ss. yes it will fit. it is the same engine.
4l60e
yes
Well depends on how much work you want to do. The engine will fit but the mounting locations are different because 98 was the first year of the LS1 in the Camaro. You are better off with an LS1 it is a much better engine anyways! Well depends on how much work you want to do.

With the advertised 88 HP and manual 3 speed trans, 99 mph.With the advertised 88 HP and automatic trans, 98 mph.
The LS1 was introduced in the Corvette in 1997, and made its way into the Trans Am and Camaro in 1998. The Camaro Z28 and Trans am were advertised at 305 hp and the SS and WS6 at 320. Ratings stayed the same until 2001. The 01-02 SS and WS6 models were rated at 325 thanks to an LS6 intake manifold borrowed from the Vette. However a slightly smaller cam was used to keep power at the same level. The fact is an ls1 is an ls1 reguardless of year or model. The SS and WS6 cars will NOT dyno higher than a Z28 or ls1 formula. All 98-02 LS1 cars dyno 280-300 with the A4, and 300-320 with the m6. Forget about the GM ratings. All LS1 cars are good for 350-360BHP. GM underrated these motors in order to keep sales up on the "king of the hill" Corvette.
