I ran an injected alcohol 499 low deck for approximately 10 years, 1-300 1/8 mile passes every year, 750ish hp, arp main studs and aluminum main caps, eagle crank, rods and Ross pistons, half fill, finally cracked a cylinder wall on #8...never saw a web crack...shifted at 6800, don't know if it makes a difference but this block was first in a hardtail pipe rack then a 4 link pipe rack, spanned 1998 to 2008. Scattered it all over Denton Dragway after sleeving the cracked #8 hole...( 5 Dyno pulls, 3rd pass down the track) damage was do severe myself and 2 "experts" couldn't figure out what let go first...managed to save the intake, distributor and fuel injection system...oh yeah and valve covers...(most likely suspect was something to do with 7&8 rod journal)...

It doesn’t take much of a small block to make the big blocks look silly. How many 340-360 blocks do you hear about cracking. 😂

Looks like the number 4 cylinder is cracked WAY up the bore. It must be filled or it would have put coolant in the oil.


Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

#2 ,#3, #4 main saddles were cracked up into the cylinders and the block was getting ready to split in half, no concrete.

When I broke one back in the seventies it was so bad the only thing keeping the back of the block from falling to the ground was because the starter wire was holding it on.

You have to admit, the BBM heads out there aren't exactly setting the world on fire in terms of airflow/cross section. No idea what the Chrysler engineers were thinking really.

No offense intended to anyone with asthma!

I have not cracked one, but the highest HP I've put through one at the track was around 620 hp.
It was/is a 14:1 stock stroke 440 that ran 10.40s at 128-129 mph at 3700 lbs. Ran it for a lil over 3 years and never hurt it.
That same motor is in another car but is making around 700 hp now. It is probably a time bomb, but I'll run it til it dies...if I ever get the rest of the car track worthy.

I know Mike Daurity split the main webs and a couple cylinder walls in his low deck 512/400 stroker in his street car '69 super bee a few years ago. It's around 600 hp on motor plus a small plate system.
