Well you can have the block drilled and tapped for 1/2 inch head bolts which is not a very uncommon upgrade anyways... When you do this you also need to have the heads drilled in the same respects.. Check around for pricing as different machine shops will quote you very different prices.. If not you can also buy a new block and they run anywhere from $400-$500... Sorry to hear about that... Good luck with everything.. Hope this helps..[sm=sorry.gif]

i cant just drill the block out myself because the motor is still in the car and what about a heli coil

OUCH good luck.Those easy out are hard as Sh**.You will need diamond tip bits and will be a pain in the a**.You would be better off pulling it and having a machine shop do it or get a diffrent block.

man that blows... only thing i can think of is cooling that area down with lots of really cold ice, soaking WD40 in there and hope that wrestling with it will get it loose.

we tried drilling it out and got a big mess now it was hard to work on since it was the back bottom bolt now i think we might have drilled into the block a bit and wrecked the threads i guess i should of pulled it out[:@]

I would go with what mstng5l67 saud, drill and tap to a bigger size.. A lot of people do it for stronger bolts, but in your case, it may save the block... Good luck.

C/Note

get a small punch and try to chiesl out the easyout...then get a left hand drill bit..and see if it comes out ...i been there ,,,sucks![&o]

dude two words.........MACHINE SHOP!!!!! i have had the same thing happened to one of my customer's supra.we didnt even wasted time drilling it out and sent it to machine shop.they charged about 80$ to drill and helicoil the block.drilling through easy out isnt gonna be easy.i had a broken exhaust manifold bolt and tried easy out..............but it broke inside .wasted two drill bits and bought steel/hard metal or cobalt tipped(cant remember which one) bit and still it wasnt that easy to drill.save some time and frustration and send it to machine shop.
