What I meant was, everyone wants to know the power level this will take, what that will take. That's no clear cut answer. Yours may take 500HP. Someone else's may take 650. The rest of the question is always left out. How much will it take "before somethin bad happens", so I always say "until it splits apart" or "until somethin bad happens", because you simply never know there are so many variables.
Where your assertion I brought Ford into this came from, I haven't a clue, but if it makes you feel better.........I'll tell you the story of a childhood friend of mine named Mike Mason. Those that have me on Facebook can at least verify he is on my friend list.
He had a 89 Mustang I believe it was years ago.......had like 93 front and rear facias on it. It was a "oddball" cubic inch displacement, because he got the wrong rotating assembly but built it anyway. A 382 or some such if memory serves. Stock 351 block based engine.
He never got on a chassis dyno that I know of, but that car used to run 8.40s all night long at The Silver Dollar Raceway in Reynolds, Georgia. He even used to get it out to the local Brewsters ice cream store in North Macon. He even kept the 8.8 rear axle under it until of course the inevitable happened and then he went with a Dana. I lost track of him sometime around then, but now he comes in the store almost every Saturday with a mutual friend, Mark Byrd, so I can ask Mike what became of the car and engine. I think he sold it, but it may still be around.
Mark, (also on Facebook) has a 1500 plus HP Chevy 1500 5.3 "street truck" with one large by huge turbo under the hood. Mark's race car is called "RIP"
Here is RIP makin a pass.
They are finally gettin that car worked out as evidenced by it "gittin with it" in this video. All I know is the car is "between this HP level and that" since it's a money car and they won't say. The turbo on that car is 2 or 3 times big as my head. Search more on youtube, he does a kinda walk around on it. It's a very professional car.
Will that block eventually fail? Probably, but not before it makes them a lot of money, I bet. And we've been talkin about 650 chump change here? lol
Yeah i know but there are always some kind of general level that is somewhat safe to stay under even thought it may not be guaranteed that it will last, i know people are alitel cautios about giving this kind of advice for good reason,but i feel safe in saying that im aware that sometimes **** blow up far below what the parts should be able to take and sometimes they survive a bunch more than they should.
Just trying to bring back some good old hotroding into a hobby where alot of people seems to have got stuck in a mode of buying all the latest and greatest and doing things that are certainly not stupid but may be overly cautios so to speak.
The Ford reference comes from 302 Ford smallblocks being known to literarly split in half,blocks cracking straight thru the mains and camtunnel at some lever of punnishment that seems to be lower than what mopar smallblocks can handle.
That Camaro hauls it! nice!
From what little research i have done on Magnums they seem to handle alitle more punishment than LA blocks and comes with a few nice features such as one piece pan-gaskets, supposedly alitle taller lifterbores wich should be a nice feature,multirib belt for accessorys, better heads than LA motors(except that they seem to crack often) and that bolt angle on intakemanifolds should be nice,also found that they probably have the best intake manifold (indy)for big power available for standard heads.
It seems as if Magnum heads where a popular conversion on LA shortblocks 10 years or so ago then everyone went for edelbrocks and then later EQ or RHS heads but the stockish shortblocks dont seems to have many friends at all.
