What length connecting rods should I use in a 383?

Most 383 small-block stroker packages prefer the stock 5.70-inch-long 350-style rod, but there are also advantages to going with a 6.0-inch rod. A longer rod further reduces rod angularity during the combustion cycle, which reduces the side load on the piston and cylinder wall.

What makes a 383 small block Chevy?

A 383 stroker has a 0.030 over bore of the stock 350, giving you 4.030 as a bore diameter. Putting the 400 crank in the 350 increases the stroke to 3.750. Other than that, all the other dimensions stay the same. If you do the math, you will get 382.6; round up and you have 383 ci.

Does a stroker kit add HP?

However, the horsepower output will largely depend on the overall combination you are using. We could take a 500″ short block and with stock heads and a mild cam, it might make around 450-475 horsepower.

What cars came with a 383?

The 383 served as a mainstay for police prowl cars. From 1967 to 1971, most law enforcement agencies equipped their Dodge Coronets and Polaras and Plymouth Furys and Belvederes with high-performance 383s. The Dodge cruisers could be equipped with two versions of the 383 with horsepower ratings of 270 or 325.

How much HP can a Chevy 350 handle?

a typical 350 Chevy can make upwards of 350 – 375 HP before you exceed the reliability of the components. For a big block with the same stock components it can make in the area of about 400 to 475 or so HP and handle upwards of about 500 HP before you exceed the reliability of the stock cast pistons.

Are stroker engines reliable?

A few years ago stroker motors weren’t very reliable but with testing and redesigning now they are almost as reliable as a stock motor as long as you treat them right.

What are the advantages of a short rod 383?

Compression and combustion pressures are in opposition to the inertial forces so the top of exhaust and intake strokes generate the largest forces on the rod. This table is for a 3.75″ stroke used in a 400 0r 383 small block Chevy engine. Percent difference due to rod length in above table.

Where does the 383 Chevy short block come from?

The short block is derived from the original ’95 Corvette cylinder block. A complete rotating assembly from SCAT Enterprises transforms it into a powerful 383 street engine. SCAT components include a forged crank, Pro Stock I-Beam connecting rods with 3/8″ cap screws, customer specified forged pistons, rod bearings,…

How does a 383 Chevy hot rod engine work?

A complete rotating assembly from SCAT Enterprises transforms it into a powerful 383 street engine. SCAT components include a forged crank, Pro Stock I-Beam connecting rods with 3/8″ cap screws, customer specified forged pistons, rod bearings, main bearings & piston rings. This is an internally balanced assembly with a 1-piece rear main seal.

What’s the rod to stroke ratio on a HT 383?

This gives the HT 383 a rod to stroke ratio that is 1.5, which is less than the 350 ci’s ratio of 1.52 and the 1.6 ratio if you use a 6″ rod in 383 ci stroker?? So what gives that GMPP doesn’t care about rod/stroke ratios in their new crate motor.
