NO I dont claim to know why or how Alex blew his engine? I dont know how much HP OR MILEAGE he had. BUT I KNOW HOW HE DRIVES!!!!HA-HA He also took a chunk of #1 cylinder with it-or did the cylinder take the rod?
WE can speculate how this happened......Could of been a misfire, KR, detonation, a bad wrist pin, or a stress fracture in the block due to a core shift in the manufacturig process????? Or the rod could of plain just failed. By itself, probably not.
I know the weakest part of the rod is the bolts-so APR's are recomended if you want to retain the stockers. So would a good set of bearings and a BALANCE JOB! To me these L67 rods have a good reputation for handling power-the whole bottom end does. Just look at the main design with the cross bolted mains-thats NASCAR technology!
Whats my point-well 90% of the time a engine doesnt fail for for one reason. It will fail for any number of predisposing factors or circumstances (some of which are described above). Hypotheticlly speaking, the same thing will happen to the L32 rods if the same conditions are present-it just may take a little longer. Hopefully you'll recognize it before it happens-thats the art of race engines-tune.
What does this mean? Dont refuite the stock rods performance or get complacent on the L32's. A set of fluxed, balanced,(good condition)L67 rods in heavily modded streep/strip car is not destin for failure-under the wrong conditions they are.
I want to be clear on this so I dont start a cock fight......Im not saying Alexs car was wrong or say exactly what the failure was. Im trying to convey the circumstanses under which failures DO occur and clear up any misconceptions about the L67's rods. We dont see alot of rod failures in these cars-pistons usually go first(in my case)And that was cause by KR. I didnt see it then, but I see it now. Thats what im trying to say....
