My next 454 build

[Rizzle]

I've seen quite a few guys on builds use those inexpensive cast pistons and I know almost all those builds ended up with catastrophic engine failure when pushed at 6500-7000 rpm blasts. I would highly recommend that is you are going to use lesser cost than 2618 forged pistons, you should at least step up to a 4032 forging (hyper-eutectic)that many quality piston manufacturers offer and the weights will be substantially less. I am not a pure fan of these but they are heads and shoulders above those heavy cast pistons.
Don't buy this engine twice! JMO

I do not believe 4032 is a hyper-eutectic alloy. While it is higher silicon than 2618 it is not hyper-eutectic. Its a great material for pistons, and has some upsides vs 2618 mtrl when put to street/high hours use. Its about picking the better alloy for the application, when both are available.

You are correct I misspoke thinking about cast pistons that some are hyper-eutectic, not necessarily so. 4032 allow is higher in silicone than 2618 and as such is harder and more brittle than 2618 but both alloys are used in forged pistons. As for the cast pistons shown on the post, I do not know the aluminum alloy of this brand as I NEVER use cast pistons. I have used quality 4032 forged pistons from several manufacturers in mild NA applications and have had good results over the years . I have also seen 4032 forged pistons used in high rpm, nitrous and boosted applications where the brittle aspect showed its ugly head with piston failure and engine damage. That's why I feel that in nitrous, boosted or big power adder applications 2618 alloy is my piston material choice. JMO

Curious as to how this build is going?

I wanna see some porting pictures

Its coming along, just keep in mind I have many many engine projects going. You can be sure it will get done, my car needs a engine.

When I have them done I will post them up. Knowing the altitude correction factor for Denver is .9405, how far into the 10s will my new project run @ Denver? Anyone........I need some motivation.

lol,, sounds like your in control here. Surprise us.

Ok- 10.78 , that should at least start some motorvational debate !

Are those homegrown windage tray bolts?

[Newold1]

Good question. Vortecpro are those studs welded to the top of the stock main cap bolts?

Thats the exact number I'am hoping for.

Yes

I was able to test the peanut port 467 right out of my car today. My 467 peanut port original dyno test before it went into the car (my peanut port 467)
Picture 3411 is as the engine came out of my car.

Yes

I am not a fastener expert but if these bolts have been brazed or welded on they are not acceptable for any engine. The temper, sheer and yield strength will have been changed with heating and will not stretch and hold at the specified torque setting. Thanks, Charlie
