11.5 time bomb

Post pic's of the rod bearing.


I'd think detention would take out the rod bearings 1st. That looks like either the caps are walking or the clearance is to tight on the middle caps.

One cannot tell if the caps are fitted properly by trying to move them by hand.  The combustion process places hundreds, if not thousands, of pounds more force on them.

I agree, Jeremy, that detonation will take out the rods first and probably break the crank before it destroys the mains.  I think the machine shop gets the blame on this one.  Of course, they will assure you that they were perfect but we used to see a lot of these before we learned that the factory used a broaching cutter on the block and the aftermarket  caps would not fit properly without reworking as Brad described.

Most guys aren't going fast enuf to require steel main caps...girdle etc. Nothing wrong with going that route...but you'd better find a machinist that knows his shit...or you'll end up with all kinds of issues.

thanks for all the post,I had time today to take these pic #1 and #4 all look the same but #3 has some slight
damage.My next block will be done by someone that know his $#!t from the mainland.I put it together with .002

Tim how much will it cost you to send it to the mainland and have it done again?

[Tim Hensley]

$450 -500 both ways and it will weigh more coming back

[Tim Hensley]

450-500 each way not round trip

Plus the build?

Looks like that second pic might have hammered the bearing a little. Looks like the trash from the mains went thru them too.

I'd talk with a reputable builder - but it might not be cost effective to continue with your block and caps. It they screwed up the line bore/hone things will just snow ball.

The problem with align honing is that the cam and crank are brought closer together. Align bore is far superior...in that you can take most of the 'meat' from the cap...and a minimum from the block.

Yes getting a different block,wish I could find  a new block and a TA  is way out of my needs , just a bad pic no hammering just trash.

I have a 4.1 block that was purchase in B/G and the build didn't happen comes with rods and piston. $500.00 plus the ride.

Arizona gn came through with a 109 and will build me short block ,i chose not to do a stroker
