PISTONS MELTING EXPLAINED! 

Thanks!

Are you the same Santos "King of the 3TC". I used to work at Toysport in the late 90's.

@@ramirodiaz4545 I think u thinking of Santos Turbo from Florida but I have been in the game a long time as Well still luv those 3tc and 2tc engines got a bunch of them parts are plentiful now days and so is the better tech due to Santos turbo,PSI Racing and such guys

Thanks!

408 will have enough power even on a truck! Keep that quench tight and lower gears out back will help keep it from detonating! Do you have a camshaft in mind already?

@@benalamedaracing2765 I just bought a Ford 9inch at the turkey rod run it has 410 gears. In the process of doing a crown Vic front end swap. I do not have a camshaft yet. Probably a custom grind from Anderson or Iskey cam.

Thanks for supporting my channel Ronald.

Thanks!

Thanks Greg!

Thanks!

Thanks for watching!

These things usually happen when we are making good power and the ignition and fuel are on the confused side with errors producing this conditions.

Methanol plus coated pistons sides and top will give you excellent durability compared to any gasoline even E85 is superior! In fact the most on a stock block gasoline boosted power I max out below 600rwhp. With just E85 I have done over 630rwhp without any issue with the piston or bottom end. Also keeping the rpms well below what we run with gasoline will make it last long.

Thanks!

Thanks!

Stuart, it is hard to equalize the mixture distribution all around the cylinders because of the momentum of the incoming charge column will slam and separate the A/F ratios all over the place! I will do a video further explaining this scenario to make it even more clearer. Tight quench will help distribute them but unfortunately the spark ignition flame already got going before it can self correct the rich/lean areas! Thanks for supporting my channel!

Most melted pistons always failed around the same general area of the intake relief closest to the cylinder wall. Before it happens when caught early you will see this area is rough like a sandpaper texture. Rings are rotating all the time and if the end butted together from not enough ring gap you are correct. However, it always fails at these same general location indicative of its lean conditions adjacent to the cylinder walls. Every time this fails the owners/builders tells me they had more than ample enough ring end gap, and the reason some builders fail to realize is the position of the top ring being a concern because what works for a ring pack that sits .250-.300+ will require a set ring gap and this same situation changes dramatically when the ring pack sits @ .150 sometimes even less! Then you have issues of heating with not enough material above the top ring making failures even more possible. Obtw, if the rings did butt together there will be an indication of cylinder wall scratches or wall damage and many times it does not anywhere and the top piston lifted up. Wall damage if not for some parts caught in between the cyl. wall and piston will show scratches and most of the time there is no such evidence of wall damage and the piston top is obviously gone! An indication of ring(s) far from butting together...

You do not want the sparkplug on the intake side because the prevailing spark burn front must start at the center of the cylinders where it is most effective. Besides most of the richer side of the chambers are closer to the exhaust valve more than the intake so we must burn these much earlier!

Evan, yes if it is too deep it will intersect the top ring groove and it will be a short day! Thermal barriers is always a plus for me and is good practice!

Yes it does...

It is ok because other cylinder heads have also one quench pad and it is a lot better than nothing! LS heads also exhibit above normal swirl and tumble characteristics so that helps big time!

@@benalamedaracing2765 thanks for the response BEN ! Im at 0 deck with 4cc dome pitons and 4.100 x .051 head gasket , thinking Im gonna get a 4" x .040 gasket set and redo my quench soon

When pistons hit like these with debris from spark plugs make sure to install the rings and rotate around the pistons making sure the ring lands are not caved in and sticking or stuck! Seen these things and people miss it altogether and it does not take much to push down and pinch the ring lands from debriss on top of the engine.

Yes you got it right wherein the excess fuels does contribute to cooling with "end gases" on the combustion chambers and pistons,

Thanks!
