auto/S197+ boost, beware...
Auto S197s be careful with your overdrive and boost. I ended up blowing my motor yesterday night during a speed run with the OD off. When it redlined I popped the OD button back on in order to drop the gear/revs and engage the final gear, it ended up overboosting or something because it blew a 3inch hole in my block, snapping one of the rods. I let up on the gas briefly before giving it gas again after the OD kicked back on, pretty sure the hard shift, plus final gear engagement is what killed the rod... not sure how exactly, but it sure as hell did.
Getting ready to drop a stock short block in there. Not enough money for an aluminator just yet. Better to have it running than no car at all.
The auto tops out far too quickly w/4.10s, OD off with the addition of a blower, so anyone thinking of this combo; beware. It had great power down low-mid and some top end but honestly, the top end really was not all that great (80-140)
I was only about 400whp/380-390lbs trq.
Not sure if I want the blower back on or not. Kinda bummed, but this gives me the opprotunity to do a motor swap, so I am pretty excited about that project...

thought I'd be able to.. not so sure now. I'd be happy with a stock short block honestly. I'll try and get pics up later of the hole in this block..

sorry to see it stealth.....if you are going to buy
a new ford short block, imo you can't beat buying
direct from tousely ford....here is the SB that you
will want. it probably sells for around $1700 maybe
a little less.

so in the end, all things being equal, the difference between being
forged and not, will be around $1500. my vote is go forged. good luck
and i hope everything turns out well.

Damn wtf you just installed it.
It sounds like to me that the engine load from O/D plus the high RPMs is what killed that rod.
Are you going to put different gears now? You could just run a taller rear tire.
