you realize, these blocks are built from cores, that yes, are inspected thoroughly before going into the rebuilding phase, but they are afterall old motors that have been in cars previously.
Case in point, my 2.2 stroker was built from a neon block, some of the bolt holes in my block had NEVER had a bolt in them yet, and yea I had to run a tap in 'em just to clean them up, but if I was putting a $3000 block in any car, I'm going to check and DOUBLE check every small thread on it just to make sure. It's calling knowing how to do things right.
You put a HARDENED bolt in the hole to clean up the threads, problem is they're not notched and don't have points the stress can release at like a tap does, so no wonder you cracked off the corner of your block. I know of about 12 other people personally running Howell blocks, and we've never ever ever had a problem with ours yet, maybe it was just an ID 10 T error here 97 Dodge Avenger a670 reverse manual 3spd swap, 3400 stall, 2.2 stroker, zex setup, 8 fuel injector setup, t3/t4, turbonetics wastegate, and a slew of other mods to go fast BEST ET: TBD 03 srt-4 Stage 1, exhaust, TB, map clamp, wga and mbc.
