The eninge in the pics was that one that the PO had spent $18.5k on getting fully rebuilt. Something was out of balance but he kept driving. He then lost 4th gear so was driving at 4500rpm in 3rd when it went bang. So reading the advice from others on breaking-in, what damage do people think may have been done by running at high rpm's continuously early in the engine's life - what should I be looking for?
I will ring up the shop that rebuilt the engine to see what sort of break-in (if any) they did. They knew he lived 700km away and was going to drive the car home so surely they would have done something to prepare it? But then again, the motor did blow up...
As for cutting out the radiator support bracket, that is what I did on Frankenbenz (with the 450V8). The only advantage in doing that is you don't need to remove the bonnet to get the engine in. I drilled out all the spot welds to do the job neatly and then I got someone to put nutserts in the body. I simply bolt the top piece back on. However, you then have to battle to get the alignment right, as the bonnet (hood) latch is on this piece. Either way you go (removing bonnet and tilting vs cutting out support and bolting in), you either have to align something up - either the bonnet, or the latch. Unless you plan on doing engine changes frequently, I would not bother. I have put pics up here before of my set-up.
