Pistons and connecting rods for a 406 SBC

Whats a good set of pistons for race/some street use in a 406 small block chevy motor? I would like to stay with pump gas and keep the price down pretty low. Probably gonna be using Dart iron eagle platinum heads, probably the 215cc size. Probably also gonna do a short fill on the block.

forgot to mention I'm thinking 5.7" rods, kinda shying away from the 6" ones due to price and some not so good things I've read on them.


thanks

Do a search here for 406 build or something similar.

Myself, I'd use JE forged flat tops or possibly a small dish, depending on what I want the motor to do and what future plans might include, say a shot of nitrous, etc.

You need a goal, hp level, torque, what vehicle, trans, gear rations, tire size...

And why fill the block on a street motor? That's taking away a lot of cooling capacity.

I've searched everything to do with 400 and 406 here and read it all.


goals=max power with iron heads and pump gas.

torque is a big deal, but needs to be a race type motor that can be on the street some.

87 chevy 3/4 ton 4wd pickup

4:11 gears for now, will be going lower eventually. 36-44" tires, not sure yet but will gear accordingly

turbo 400 trans.

purpose mud drag racing and bog style races. possibly a little pulling every now and then.


filling the block so that this motor can be run hard and not have to be an under 5k rpm motor. its a 2 bolt main 330817 block with 2 freeze plugs in each side.

I short fill(bottom 1-3/4") all the 400 blocks I use also, doesn't really affect cooling as 90% of the heat is in the heads and first 1" of cylinder wall. I have no problems with them on the street with a large radiator and good pump.

For what you are doing I would look at Scat Procomp I-beam rods w/7/16 bolts, or Scat or Callies Compstar H-beams. For a crank Scat forged, Callies Compstar, the new Manley, or Howards. Probe, SRP(JE),Wiseco, or Ross for pistons, flat top or dish depending on head chamber size.

When you get to this level of pistons you also have the option of going to 5.850" rods, common in use in 410 Sprint and Modified engines, to get a longer length than 5.7" but not get into the oil ring issues associated with the 6" rod.

i am with the majority on this scat rods and crank 5.7
wiseco or good pistons and the cam is prob the most important
I build alot of 400s and love the low end torque
for the heads you have you should have a great set up

eagle scat crank and rods are decent in the less expensive end. Wiseco pistons are pretty good or anything mentioned above so far. A little solid roller cam with those heads and 10 ish compression ratio and I think you will be happy.you have to decide how hard the engine will be beaten and what kind of power you need. The price of horse power goes up quicker than the horse power figures
