Dang...

Not sure i would put much stock in the flywheel HP number - only 10% loss through the drive train seems pretty low compared to what I've seen.

No one with the IQ of a fruit fly uses wheel HP to calculate ET. No one. Why Wallace even uses that is beyond me because it’s useless.

Just like using ET to calculate HP. Doesn’t work.

He said that it was a 0.030" over bore, if a 318 can't handle that, we're all in trouble. I know that you was using the 0.010 over bore 360 as a example.

I never heard a thing about .030 over, he clearly stated its 408 cubic inches, so explain how much stroke it would take to get 408 out of a .030 over 318.

The only thing learned in this thread is that if you ever blow up a motor, don't mention it on this forum

only if you lie about what it is, otherwise you're good

Here @Dan the man this is where he says it's a 408 stroker

Just an observation on the 2 numbers the calculator spat out.

I agree with you 100% but it's not something to get upset about is all It's not like he's straight up lying to people about what it is.
BTW.. i was curious.. is it possible to go bigger than 4" in a 318 block? 4" seems to be the magic number everyone goes with

Are,you asking about bore, or stroke? More stroke is possible. A 4" bore in a 318 is shaky. More than a 4" bore is extremely risky (NOT a good idea). If i had a 318, id probably build a 392 out of it.
Edit: poly 318 blocks can probably be bored bigger than an LA 318.

.030 over 318 bore, with a 4.180 stroke=407.7cu in. So now where did he get a 4.180 crank? (Hughes? Ohio crank?)

Never realized it only takes 500hp to run 10's.. thought it was more for some reason

Depends A LOT on car weight and setup (how dedicated as a race car is it?). I've been high nines with around 500 crank hp, (est. 400rwhp.). But my car was around 2400 lbs, with me in it. 500 hp in my 3500 lb car was very low eleven.

I think I have a screenshot of one of his videos way back when he posted it was a 4" stroke deal. He loves to call it a "318" because it makes him look like hes accomplished something no one else has. It's all internet bullshit

To me it also reeks of street racer bullshit. Same think as playing bullshit poker with the serial numbers on the bills in your wallet.

I would agree with the split cylinders causing the engine to hydraulic and come apart. Kinda surprised it does not happen more.
After sonic testing a smaller sample of small blocks and big blocks I would never bore more than necessary. The engine is only as strong as it's thinnest cylinder.
I would think the modern hemis would have more uniform casted cylinders? Maybe not as thick as the older LA blocks but less thin spots. That's just my assumption.
If I had a garage full of the newer hemis I would go that route. Start building that BGE block to an actual 600 HP.

 

[Dan the man]

Dan, he said it was .100 over. That makes it a 4 inch bore. And he didn’t sonic test it. That’s stupid, as the results show.

My bad I thought that he said 0.030
