How much torque does a 350 small block have?

How much torque does a 350 small block have?

380 lb-ft
Like the 302, it was based on the 327 block, but the 350 had an all-new crankshaft with a 3.48-inch stroke. The first version, dubbed the L-48, produced 295 horsepower and 380 lb-ft of torque. The 350 became available in the Nova in 1968 and in its third year it was optional across the Chevrolet passenger car line.

How much torque does a 5.7 350 have?

5.7 Vortec Engine Specs

How high can a Chevy 350 rev?

Basic 350s won’t rev beyond 5500 due to induction and exhaust limitations, but they should be reliable to 6000 as long as you don’t run them out of oil.

How much horsepower does a 5.7 350 V8 have?

Chevy 350 is a 5.7L, small-block, V8 engine featuring a 4.00-inch bore and a 3.48-inch stroke. The power output from this engine varies from 145-370 hp, depending on the generation or version.

What is the torque on SBC aluminum heads?

Torque specification is 45 lb/ft. Be sure to put thread sealant or RTV silicone sealer on any stud or shaft bolt that threads into an intake runner, and use anti-seize lubricant on any stud or shaft that is being threaded into aluminum.

Can you reuse head bolts Chevy 350?

A head bolt should not be reused if the threads are galled or badly damaged. Chasing damaged head bolt threads with a die will clean up the threads but also remove material (metal) and undermine the head bolt’s ability to torque down and hold to specs.

Can you over tighten exhaust manifold bolts?

YES… you can and probably did overtighten them.. When it gets hot it can crack if overtighten to much.

What torque should exhaust clamps be?

Well-Known Member. Yeh I believe most manufacturers say about 40 ft lbs. There is no reason to crank down on them with an impact, you can actually deform the piping or break the clamps. Tighten with a ratchet until the nut just stops turning and may 1/8 turn after, not cranking on it, and that is likely around 40-50.

What is the max RPM on a stock Chevy 350?

Yep, redline for a crate motor is 5500. Above that the first thing that starts happening is floating valves. It doesn’t take much valve train work to get those engines to 6000, and with some work they will do 7000 RPM. Yep, redline for a crate motor is 5500.

What is the torque on the exhaust manifold bolts?

Torque all of the bolts to 11 lb.-ft. on the first pass and 18 lb.-ft. on the second pass. The exhaust manifold heat shield bolts go on at 80 inch-pounds (not foot-pounds), the pipe-to-manifold bolts go on at 26 lb.-ft. and the manifold pipe nuts spec out to 26 lb.-ft.

How much torque do I need for a manifold?

Some manifolds house different sensors and plugs, such as a check valve or exhaust plug. The different elements require less torque than the bolts on the manifold. Use between 10 and 17 foot-pounds of torque for those elements.

How much torque is needed to install an exhaust pipe?

The solid structure to which the pipe is bolted is the exhaust manifold. Installing a manifold requires careful torquing of the bolts. Every vehicle has different levels of torque necessary to properly tighten its bolts. The standard is to use 20 to 30 foot-pounds of torque.

What is the torque on the LS1 exhaust manifold bolts?

Torque the LS1’s exhaust manifold bolts in two stages. Torque all of the bolts to 11 lb.-ft. on the first pass and 18 lb.-ft. on the second pass. The exhaust manifold heat shield bolts go on at 80 inch-pounds (not foot-pounds), the pipe-to-manifold bolts go on at 26 lb.-ft. and the manifold pipe nuts spec out to 26 lb.-ft.
