You asked: Is a 350 an interference engine?

Technically they are not an interference engine. Lose a chain at high RPMs and the valves could float and make contact but at low RPMs they will not touch. This is not correct. They are absolutely an interference engine.

Is Chevy 350 an interference engine?

the answer is no not normally but there is a qualifying statement i need to tell you,most chevy engines are non interference but if your travelling at highway speeds about 55 or faster and the timing chain jumps time the valves will float out at that rpm and the pistons will hit and bend them,at low speed it will never …

Is a SBC an interference engine?

The SBC is an interference engine and always has been, although I admit they will sometimes survive a chain failure without bending anything in the valvetrain. Some SBCs, particularly those with small valves, small cams and heavily dished pistons, can sometimes survive a chain failure without dinging a valve.

What cars have a 350 small block?

L48. The L48 is the original 350 cu in (5.7 L), solely available for 1967 in the Super Sport (SS) version of Camaro (1967-up) or Chevy II/Nova in 1968–1979. In 1969 it was used in almost all car lines; Camaros, Caprices, Impalas, El Caminos, Chevelles & Novas.

Why is a 327 better than a 350?

In the vehicle, it’s more of a matter of “gearing” than revs. A 327 with it’s shorter stroke would need shorter gears so it can GET to its revs, where a 350, with its slightly longer stroke and more torque output will pull a little taller gear than the 327 will.

What year Chevy 350 is the best?

The 1975 version of the LT-1 ultimately succumbed to new emissions standards that brought its horsepower all the way down to 145 HP. The LT-1 was the last and arguably greatest of the old fuel-guzzling, emissions-spewing 350 engines. Those original LT-1s from 1970 will go down as some of the best engines of their time.

Is a 327 and 350 block the same?

The 327 uses a 3.25 inch stroke, where the 350 uses a longer 3.48 inch stroke(thats what makes it bigger). Depending on the year of the block, the biggest difference in the block itself is the main journal size.

Are interference engines better?

In comparison to non-interference engines, interference engines “breathe” better because the valves can open earlier, close later and open wider. Interference engines can also achieve higher compression ratios. These designs extract more power, use less fuel and generate fewer emissions.

What happens if a timing belt breaks on a non interference engine?

If the timing belt snaps, they run into each other, causing bent valves (most common), cylinder head or camshaft damage, and possibly piston and cylinder wall damage. … In a non-interference engine, the pistons and valves don’t occupy the same space, so if the timing belt snaps, no valve or cylinder damage occurs.
