What is the length of a 351W pushrod?

According to Comp Cam’s website the tool is for 7.8 to 8.8 inch pushrods. My stock pushrods measure 7.53 (remember it’s a roller block) as measured using a 12″ dial caliper. Measuring with a caliper will not take into account the oil holes, as I believe the stock length for a roller 351W is 7.567″.

How long are big block Chevy pushrods?

The adjustable pushrods come in five separate lengths from 5.800 to 10.800-inch. Each pushrod will offer one inch of travel. For example, the 10.800-inch version pushrod tool will extend out to 11.800 inches.

Why are LS7 pushrods longer?

LS7 heads need longer pushrods because they have a rolled over 12 degree valve angle AND longer valves, both requiring longer pushrods. LS3 heads are 15 degree and have stock length valves like any other LS1/2/6 heads. The “deck thickness” as far as how thick it is cast has nothing to do with pushrod length.

When did the Chevy 235 6 cylinder engine come out?

Chevrolet 235 Inline 6 Cylinder Engine The Chevy 235 inline 6 cylinder engine was first introduced in 1941 and was mainly used in large trucks. In 1950, GM decided to use the 235 in several of its automobiles that were going to have the new Powerglide automatic transmission.

What’s the difference between a 235 and a 235 engine?

This engine was very similar to the 235 engine, except for a different block casting with a larger piston bore of 3.75 inches (95.25 mm), two extra coolant holes (in the block and head) between three paired (siamesed) cylinders, and a slightly higher lift camshaft. This engine was offered as a step up from the 235 starting in 1954.

What kind of engine was in the Chevy Stovebolt?

This pushrod six-cylinder design was only engine offered by Chevrolet from 1929 until the advent of the small block V8 in 1955. The earliest of these engines were known as “stovebolt” sixes, because the bolts that held the engine together resembled the bolts that were commonly used to assemble woodstoves.

What was the output of a Chevy straight 6 engine?

A four-bearing crankshaft was added, along with 6.5:1 compression pistons, for 85 hp (63 kW). A new cylinder head in 1941 increased output to 90 hp (67 kW), and 6.6:1 compression gave the 1949 model 92 hp (69 kW). This generation did not use a fully pressurized oiling system.
