They say there is no dumb questions ,here goes , What will happen if I remove thermostats and run without them ?
This is a looper ..not a crossflow and t-stat's are easy to access.The Tstat housing is such a pita to get at that you will never ever wanna have to go in there again!
This is a old racers trick and is good for high speed use only. Not using t-stat will cause a engine to run cold, rich at idle, incomplete combustion leading to carbon build up, ring breakage from ring land cabon, cold seizing of piston if water to cold and engine hammered right off trailer as piston expands faster than cylinder. If engine didnt need them factory would have installed them.......But you do need to restrict the flow. Some folks use ss fender washers, bleve it's the 1/4" ones that fit into the manifold perfectly. Others nip the guts off the origional thermostats & reuse just the flange.I have it on purty good authority doing so won't cause any ill effects.
Like I said, don't everyone rush out & remove their Tstats, 'specially if they run in cold water.This is a looper ..not a crossflow and t-stat's are easy to access.
