flat top pistons

[maynardtruckin]

I have had several still have a 4 bolt main builder and a 2 bolt main runner. I have plans for the builder not sure what I will do with the runner its a mildly built 400. has a rv cam Edelbrock intake down side is the cheep chrome tins but it runs like a dream.

Torque is what I'm after more than anything, and seems like they have plenty when they're running right. I think I'm going to be happy with it.

I didn't bother to read through 3 pages of comments, but I'll give you my 2 cents....

If you go with a flat top, you will want to use a closed chamber head along with a piston that gets you at "zero deck".

The reason being is you want quench. Basically, this is the "squeeze" inside the chamber. It has nothing to do with CR, although in many instances it will raise your CR. What quench will do is give you a "complete mixture" inside your combustion chamber. It works by squeezing the mixture out from the "closed chamber area" and creates a swirling effect. This will give you a complete AND efficient burn. In return, it will also help evenly cool the top of the piston and the chamber. What does this mean for you? Lower risk of detonation because of the "cooling" effect achieved from the proper quench.

Also, if you go with aluminum heads you can run about a point higher on CR with pump gas. So a 10.5:1 engine will run on the same grade fuel as a 9.5:1 steel headed engine because of the better heat transfer.

Once you have decent CR and quench, you can pretty much pick and choose a wide range of cams.

I won't be able to do it right now because of all the money I've spent already but I'll look up closed chamber heads to see what they are for the next time through. Thank you.
