What makes a Chevy 383 stroker?

The Chevrolet 383 Stroker is a hot rod engine never truly created in normal production for use in a specific car. The engine is essentially a Chevy 350 block, but uses a modified crankshaft from the Chevy 400 for increased stroke and as a result increased displacement.

What is the difference between a 350 and a 383 stroker?

The difference is stroke of cylinders. A 350 has a 3.48 length of stroke making and using 350 cubic inches of engine, stroked out it would be 3.75 per cylinder making your app a 383 cubic inch and much better volume of room for air/ fuel firing chamber.

What’s the difference between a 383 and a 383 stroker?

The stroker has an increased piston speed because of the longer stroke. The rod and piston have to travel in a larger diameter in the same engine rpm. This increases the piston speed, which makes the stroker pull more air at a lower engine rpm. A 383 has the same piston speed at 2,500 rpm that a 350 has at 3,100 rpm.

How much to turn a 350 into a 383?

Re: Building a 383 Stroker, costs and challenges

It’s probably possible to build it for around $1200 everything off a 400 and 350 except for new pistons, rings, and bearings.

What year is the best Chevy 350 engine?

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.

What is the benefit of a stroker motor?

A stroker kit increases an engine’s displacement by lengthening the stroke of the piston. In a kit will be bespoke engine components altered from OEM parts to achieve this increase in stroke. They allow the piston to travel further up and down the cylinder thanks to the use of a different crankshaft.

What are the best heads for a 383 stroker?

Re: what heads would be best for a 383 stroker

I suggest a intake port volume of 195 to 210 cc for a strong High perf street strip 383. if you want out of the box best power the CNC ported heads make the most out of the box power. EG AFR 195 or AFR 210 Eliminators.

How much compression should a 383 stroker have?

For example, a typical 383 piston intended for a 5.7-inch-long connecting rod will have a compression height of 1.425 inches to create that same 9.00 deck height. This allows up to 0.025 inch of room to mill the deck to create a zero deck height between the top of the piston and the deck of the block.

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.

How many MPG does a 383 stroker get?

Around-town gas mileage is about 14 – 16.

Is a 383 stroker good for towing?

Vendor. The Chevy parts will be cheaper and a 383 built to tow does pretty good but will suck the gas. For the most part all of the small blocks of the same general size will tow about the same.

How do you turn a 350 Vortec into a 383?

How to Convert a 350 Into a 383 Stroker

  1. Purchase and install a 383 stroker crankshaft, rod and 10.5-to-1 piston set.
  2. Install a set of four-bolt steel main caps over the center two crankshaft mains if you’re using a two-bolt-main block.
  3. Install a set of ported L31 Vortec cylinder heads.

How do you tell if it’s a 383 stroker?

If the engine is internally balanced there is NO way of telling the engine is a 383 by looking. If it is externally balanced (most common) you can tell by the counterweight on the flexplate or the cut-away on the vibration dampener.

Are all 383 strokers?

With an all bore 383, you can get 2.055 or 2.08 valves but with an all stroke, the best bet is to go with 2.02 valves. The all bore heads will flow better and generally result in more peak hp. An all stroker 383 is capable of producing 475rwhp with a somewhat aggressive setup.
