Believe it or not the tune has more to do with performance than just what the reciprocating assembly is made from. Sure if you get into 700 plus HP even with the best tune parts are on borrowed time. Just remember, detonation is sorta like gravity. It WILL break stuff. You could have parts made of unobtanium and a shitty tune will turn them into shiny jagged rocks. Just ask the NMCA and FFW guys who run asstons of N2O. They have billet this and forged that. And one bad tune or a balky fuel solenoid and they still window the block. So yes, if you can pop for a forged crank, a good set of forged H beam rods and a forged piston (I like the DSS "X" skirt) even with a stock block just make sure the tune is dead nuts and a little on the safe side, especially with a power adder.
And for the record I have destroyed 2 stock block Ford engines using spray. The first one was a 160K 5.0L with a 125 shot and no retard (except for the driver). We never did find one of the pistons. The second was the stock 351 in the Lightning. 125 shot and 87 octane aren't a good match. But I also took a 3100 lb LX notch with a stock block 306 (stock crank, and rods with good bolts and an aftermarket piston) and sprayed 175 hp worth and ran 10.92 at 128 at Gainesville. I must have put 50 or 60 bottles through that little bomb and it just kept asking for more. I was tempted to up the shot to 200 but traded it before I could. And even after all that it STILL had 180-190 psi cylinder pressure on each hole and didn't use any oil. But I had that 650 AED tuned to within an inch of it's life!
