Can someone explain what a 'stroker engine' is and how does it differ from a regular Type I-IV engine?

The tern stroker engine refers to an engine that has its stroke enlarged thru the use of a larger crankshaft.

Most engine builders enlarge the bore (pistons & cylinders) only & dont use a stroker (crankshaft) in the engine.

Most common non-stroker engine combos:

Type 1
1641 87 bore x 69 stroke
1679 88 bore x 69 stroke
1776 90.5 bore x 69 stroke
1914 94 bore x 69 stroke

Type 4
2056 96 bore x 71 stroke
2366 103 bore x 71 stroke

Thanks, I fixed it :)

You have your Bore & Stroke #'s reversed. I know you meant it the other way. 69 is the common stroke. The other #'s are the bore.
