Looking at the Molnar Technologies crank with 2.100 Chevy sized rod journals and 6.125 scat pro comp I beams.

Is there an off the shelf piston that would work with this set up in combination with magnum style combustion chamber heads that would provide quench and let me run pump gas?

Just bench racing and window shopping parts right now. I like to do my research and math before I start anything.

I was looking at one of these combos a while ago...If I remember correctly Diamond makes a shelf piston for it, but I can't remember 100%, try a search on here.

OR, contact Rod Bloomer from BPE (BPE is his user name on here as well)...He can set you up with custom pistons for a REALLY good deal! And he will take good care of you too!

Is this a street engine... if so and you dont want to
rev it then I-beams will work... I dont like them...
that crank is still a reving crank.. I run a 3.79 to
8200 ALL the time... been to 9600... but I run a H beam rod
EDIT
Look at Diamond... they have a piston

It will be a street engine, but I want to squeeze as much performance out of it as I can. I'd like to get as much spin out of it as I can without going to solid lifters.

I've been comparing my build ideas to various crate motors and most of them come with I beams. In looking around I did see that the Eagle H-beams are only around 10 grams heavier. Do you think those would be a better choice? I was also looking at Diamond and and thought I saw one that was close on the math. Part number 11401, but I'm not sure about the valve recess location, and will a D dish piston produce a quench effect?

Planning on using a magnum 5.9 block, Iron Ram heads, Air Gap intake, hydraulic roller cam with rhoads v-max roller tappets for starters.

you might consider the Molnar H beam rods also. great product and reasonably priced. we also carry pistons from several companies.

You can use a 6.25 rod and a piston for a 4" combo...if the piston is out of the hole you can use felpro's 521sd gasket or cometic.

An H-beam rod has no advantages over the I-beam rod except I maintain it's easier to manufacture.

I have some Lentz NASCAR rods, they are I-beam and they are jewels. Oliver makes I-beams, they are near to the top if not at the top. Crower makes a very nice I-beam rod, they are tremendously strong. There is nothing magical about an H-beam rod. I maintain they have stiffness in the wrong plane, and tend to be heavier than an equivalent I-beam, although that difference is fading fast.

Buy the best rod you can afford but don't be fooled by the supposed advantages of one style over the other.
