Can you put 350 Vortec heads on a 305?

There’s both 350 and 305 vortecs. Heads from both these engines would physically bolt on to a 305, but bolting a set of 350 heads onto a 305 would hurt performance more than anything. The heads off a 305 vortec are actually pretty decent heads for a 305, and if you’re set on vortec heads, those are the ones you want.

What causes engine knock on acceleration?

This happens when there are faults in engine management sensors such as oxygen sensors, spark plugs, spark plug wire, fuel injectors, and mass airflow sensors of the fuel pump. Without enough fuel, in each cylinder, the mixtures burning time will be incorrect, causing the mixture to explode at the wrong time.

Can you stroke 305?

The 305 uses a tiny 3.736-inch bore and the same 3.48-inch stroke as the 350ci motor. While it’s relatively easy to drop a 3.75-inch stroke crank in a 305 block to create a 0.030-over stroker that displaces 334 inches, it’s just not a great performance decision for several reasons.

How much horsepower does a 305 crate engine have?

What are the specs for a 305 Chevy engine? It’s a 305 cubic inch (5.0 liter) small-block V8, featuring a 3.743-inch bore. Depending on the year and engine sub-model, you can see HP ranging from about 160 to 230.

What year did Chevy stop making the 305?

History of Chevrolets 305 Engine Designed during the oil embargo to act as Chevrolet’s efficient V8 engine, the 305 Chevy engine was produced from 1976 to 1998.

How much compression should a Chevy 305 have?

Re: what is a good reading on a compression test 86 305? 140 is fine for a slightly worn low compression engine. Like the others said as long as the cylinders are even or within 10% your fine.

Can engine knock Be Fixed?

Some of the ways in which you can fix engine knocking include: Upgrading the fuel that you put into your car and going with something that has a much higher octane rating. Taking your car in for a tune-up and asking a mechanic to provide you with new spark plugs and spark plug wires.

Can a Chevy 305 be built up?

I completely agree that a 305 can be built to make 450 hp. That’s not too difficult. The engine is limited to smaller heads with 1.94-inch valves because larger 2.02-inch valves won’t clear the cylinder wall.

Are there 305 heads on a 350 engine?

It can raise compression by a full point or more on a common 8.5:1 350 with factory dished pistons. The chambers are much smaller than old 350 “emissions” heads- 76cc vs. 58cc. Unfotunately 305 heads only came with 1.84″ intake valves maximum with many earlier ones being only a 1.72″ valve.

Can a 305 cylinder head be ported into a water jacket?

These heads will port out well, but be aware that 305 heads have smaller valves, so only look for 350 heads unless you’re specifically working on a 305. This will save you the expense of extra machining to put in larger valves. Also, if the porting technician is too exuberant, there’s the possibility of porting these into the water jacket.

What should compression ratio be on 305 engine?

They have relatively small combustion chambers, and the basic engine sports compression ratios of 9:1 or more. These heads will port out well, but be aware that 305 heads have smaller valves, so only look for 350 heads unless you’re specifically working on a 305. This will save you the expense of extra machining to put in larger valves.

What kind of cylinder head does a Chevy Camaro have?

In addition to early heads, the 1986 and later Tuned Port Injected (TPI) 350 H.O. motors, such as the Pontiac Trans Am and Chevy Camaro, are worth having. These heads have chambers that look like they’ve inherited some smog-head characteristics, but they’re sufficiently removed to fall well short of that category.
