Well, I found the limit of the stock block.....

Time for the manowar block!!!!!!

 

Here's the timeslip for the fastest time to date....This was at 3178 lbs., they had just weighed us. That's about 225 lbs of lead to make weight.

 

How do you know it didn't crack from detonation?
To much timing, not enough fuel etc.
Any block can be lost for those reasons even with a blower.
With nx that high expect anything anytime.
It come under the heading of play and pay.

 

Sorry to hear that! At least you found it before it was to late.

 

Hello Steven,Sorry about the crack,but glad you found it before things got more serious .I think I would go with the Man-O-War block and all your goodies from the old block......

 

Using Virtual Engine Calculator (cheesy, I know, but the price was right!) 851 HP.

I am assuming that was 1/8th mile.

Video was cool, but scary. That was a hard landing.

 

You now have a perfectly arguable reason to get a man o war block you lucky dog!

 

your 302block on spray

 

Dayum!

 

so what block you gonna go with now? dart? 427ci

 

Might be time for a 572 with a 500+ spray and maybe a 14-71 at 18 lbs. That'd be kinda fun.
-Tee-hee!

 

2 things:

1) I think your block took a lot!
2) IMO it shows your talent and detail to keep it together that long.

Now, what are you going to build????

 

I've seen that picture about a million times, I think that the crank let go and took the block with it. It appears that they were using stock type rods and probably a stock crank. The block is stronger than a stock crank, IMO.

 

I've seen this a lot. The crack initiates in the main webs. Then propogates into the cam journals and moves fore and aft from there. The crank tries to pull the webs out of the block. Just not enough material in there. Even with girdles and straps it will hold together for a while longer, but it will eventually let go. It's just too much stress.

 

Was that with you in it?

If so, the estimator I used says, 610 RWHP and 720 @ Engine (which sounds a tad on the high side to me but, i'd say it's ballpark)

(I used a factor of 1.5832 X your e.t. to estimate a 1/4 mile. I also assumed that you would cross the 1/4 mile traps at 135 mph (allowing you 23 mph gain - normal I'd say).
