I am planning to build a 408 or 418 stroker for my truck this winter. It will be NA and 9.5:1 CR. I plan to use an Eagle Crank (4.00" or 4.10"), SCAT H Beam Rods (I'm not sure if they are 6.125 or 6.100") and Mahle 1.105" CH Pistons (-12 CC). I'm not sure what is considered the maximum safe height for the pistons to protrude above the deck. I'm not talking about clearance with the head, I will shoot for .040" TO .050" there.

Who has some thoughts about this? I am building for torque only and I want a durable daily driver.

Thanks,

Steve

I just talked to Brian at SCAT and they do offer both 6.100" and 6.125" Rods. If I can use the 6.100" rods (will the pistons clear the counter weights and reluctor wheel), the deck height is not so much of an issue.

Has anyone built a 418 CID stroker?

I built a 402 with your combo of eagle crank and those pistons from Mahle. I had to pay for balancing the crank twice as the counterweights hit the pistons. The eagle crank is inexpensive for what you get but I think the counterwts might be larger than the more expensive cranks.

What kind of experiences have others had in the last year with balancing the 4.000" Eagle crank? I've heard good and bad.

Thanks,

I just got my 418 6.0l and I put 205 AFR heads on myself, I havent started the motor yet but I had no issues when I rotate the crank.
