Chevrolet Corvette Stingray 454 LS5 specs

Here is a Car and Driver road test of all the 1971 Corvettes: https://www.caranddriver.com/reviews/a15141356/1971-chevrolet-corvette-road-test/

This is not the LS5 engine. The 425 horsepower (gross) engine is the LS6 engine. In 1971 GM also gave out the net figures which in this case was 325 horsepower net. The LS5 engine in 1971 was rated at 365 gross, and 270 net horsepower by GM.

@fastestlaps please delete the Super8 data

@ Mike B : Check out that link! You'll find the rarest and missing Corvette. Coupe only and only 1 that ever produce with estimated Top Speed @ 180 mph. It's Corvette with 454 LS7

@ mike b : I got this data from thishttp://www.automobile-catalog.com/ They didn't say the specific engine so i just say it's LS5 cuz it's commonly use in 1971

@Fastestlaps
Can we change the figures to SAE net?
270hp/390lbft for the LS5 which had 365hp gross, not 425hp.

1971 Corvette production included 14,680 coupes and 7,121 convertibles for a total of 21,801. Of these 188 had the LS6, 5,097 had the LS5, 1,949 had the high revving small block LT1, and all the rest had the standard 350 cubic inch small block with only 270 hp (gross), 200 bhp (net).

The 454 cubic inch engine was available in two forms in 1971. The LS5 with 365 hp, and the LS6 with 425 hp. As Super8 stated the 425 hp engine (gross) was also given an official net rating by General Motors as 325 bhp. The 365 hp (gross) engine had a net rating of 270 bhp.

It's a sexy car except for that hideous lump on the hood. To keep in that 454 no doubt.

this car is very popular in my roads. see one every week.

Car Performance (Sae Net) :
325 hp @ 4800
390 lb-ft @ 3600
This Vette can accelerate faster than 365 hp version and reach 13.7 Sec @ 107 mph
