NO advantage to a fill on street unit
Save that $$ for fuel
Just because it is in the magazines does not mean you should do it. No advantage --it is used to shore up thin castings and "bandaid" for stock blocks that will be stressed beyond common sense for a stock block---in these days of aftermarket blocks--their is just no reason to do it--got a thin cylinder in a race block you want to save?--OK
Ground through the water in a SBC while stroker grinding? well then ok..but doing it because you think it will make a stock block stronger?? Forget about it--and main cap bolts are fine too , not much need for studs in most cases--save that Loot!
