Chevy man needs a Mopar lesson
Hi and welcome to the real mans car club!
The 273,318,340 and 360 are all mopar small blocks.The 273,318 and 340 share the same stroke of 3.31.The 360 uses a 3.58 stroke.The 318 has a bigger bore than the 273 and again a bigger bore with the 340.
All small block mopars use a 6.13 inch con rod,something chevy guys have to pay for!Remember basic physics,the one about the guy trying to roll a boulder with a short stick?Picked up a long one(Torque multiplier) and the rock moved...
So the 360 has a much longer stroke and thus way more torque.It does suffer from low compression and smog gear however.Some versions like the E58 police special had a 340 cam 4bbl etc but still crap 8:1 compression.So you either gotta shave the heads or replace the pistons.Offset grinding the crank will bring the pistons up some too.
Anyways thats a very simple version.Pick up How to build small block mopars,How to hotrod small block mopars or chrysler engines.
