Aftermarket block street strokers.
When you go with the 4.500" stroke crankshaft and use a 7.100" long connecting rod you'll end up with a compression height of of 1.355"
Anything shorter than that and I personally wouldn't want them on a street engine with a 4.500" diameter piston. I always ask my customers do you want to try and get the last 2-3 HP
out of it, or do you want an engine that will last. Unless you're financially well off or have a sponsor paying for regular rebuilds, running short compression height piston that require
skinny ring package are a recipe for trouble down the road.
