How much horse power does a stock 350 engine have?

Answer 1

There are more than a few variations of the 350ci Chevy motor. There are a couple of big-block 350's and several kinds of small block 350's. Other GM divisions designed there own 350 ci engines. Like the Olds 350 Rocket, which due to underestimation of demand was replaced, in some Delta 88's, with other GM 350's and this led to a successful lawsuit against GM claiming false misrepresentaion. From 1967 forward the output of the small-block 350 has ranged from 145 HP up to 370 HP.

The Big-block 350's (348ci) introduced in 1958, for use mainly in large Chevrolet trucks, came in several different intake variations of three carburation types.

Two barrell, Four Barrell, and tripower (3 two Barrell carbs) systems were used with output starting at 250HP (1958 2 barrell), and increasing to 350HP (1961 Tri-power)

The highest output 350 I know of is the LT5 from the 1990 ZR-1 that was rated at 405HP. One of 5 350's (L83, L98, LT1, LT4, LT5) available in the Corvette C4 alone. It was designed by Lotus and built by Mercury Marine. All Aluminum with 16 intake ports and 32 valves.

Tha depends on the year, and what vehicle it came in. The 350 Chevrolet has been produced for 40 years starting in 1967. You will need to be very specific to get a correct answer. Some have as little as 150 h.p. all the way up to well over 300 h.p.

The 350 in Trucks was rated at 210 HP for the throttlebody injection versions (all EFI models up to 1995) Yes ONLY 210HP. (The 454 WAS RATED AT ONLY 230 HP but they did have 450 ft/lb torque). In 1996 they switched to a Multi-point injection set up which increased HP to 255. In comparison the 5.2L (318 ci) multi-point Dodge engine produced 235 HP & 285 ft/lb Torque in 1992.
