I honestly don't understand how ANYONE can tell people that after 500hp these blocks are no good...
Ive seen it on facebook groups, ive seen it in this thread, and its always people who either look like their car makes 300hp, or have ZERO proof that they will fail at that point. I can't stand the spreading of GARBAGE information, really does a disservice to the hobby and those who want to do things.
I made (according to e/t, mph and weight calculators) around 740 crank horsepower on a stock 360 block- pump gas, solid roller, 4" STROKER (oh no, another no no!) with a 150 shot of nitrous on a transbrake leave at 4000rpm. I made MANY passes like that...Same engine saw a bunch of street miles where I would relentlessly beat the snot out of it. Even the nitrous passes were on pump gas (I was probably leaving a bit on the table, but oh well). Personally, I would feel safe with a stock block up to 800hp...Could it take more reliably? Probably, but thats my limit, and thats why the new mill in 1 of my cars is a G3 hemi with a procharger hanging off of it, as I feel a bit more confident in the strength of that block plus I wanted EFI and awesome flowing heads from the factory...But I still love the LA platform, they are way tougher then they get credit for, especially from the mopar crowd itself.
At the end of the day, if you haven't had one of these LA blocks fail YOURSELF, stop peddling the horseshit...To this day I still haven't even seen a pic of one of these blocks hurt, yet I have seen hundreds say they are only good to 500hp, and dear god watch out with a stroker....LOL
Deuces!
