got my car dyno tuned to 240hp at 18 psi and 275 ft pounds of torque and the head gasket blew on dyno well so we thought but actually it was the block that failed.

more like

did not expect that to happen it didn't get hot on the temp gauge is the thing when it blew was only at 85 degrees and there was no detonation or wasn't lean

how old is the block?

by **jacobrjett** » Tue Apr 09, 2013 4:49 pm

thats given around where one of the head bolts would tighten by the look of it. didnt overtighten the head?

by **jacobrjett** » Tue Apr 09, 2013 4:49 pm

good effort btw :lol:

by **mega4a** » Tue Apr 09, 2013 4:53 pm

nah the bolts were torqued all right and the block is an ae101 supercharged block did sit in some dudes shed for god no how long before i got my hands on it then it was all machined by Glendene engine reconditioners

how many mm where the bores?

by **rollaholic** » Tue Apr 09, 2013 6:31 pm

thats a good effort!

must have had some issues in that spot before you fired it into life again i reckon

by **jacobrjett** » Tue Apr 09, 2013 7:12 pm

yea im thinking maybe the block got dropped or something and there was a crack in it.

by **Crucible** » Tue Apr 09, 2013 7:47 pm

Thats new. Normally they throw rods out the block.

Yeah never seen that before. Very weird.

OMG so shiny! · by **Dell'Orto** » Tue Apr 09, 2013 8:49 pm

Maybe a lot of corrosion in the water jacket, and a thinner section of the cylinder wall?
