Magnum shortblock capability.

Im not going to go into the 9s on a stock crank,stock oilingsystem in a 3200pound streetcar on regular pumpfuel anyway so i think we can drop that thought. Just trying to figure out how far things can reasonably be pushed before i need to start caring about that part,i realy have no dessire to overbuild things or put more effort into this than needs to be done,yes i know for sure that alot of times its better to do everything at once and be done with it but thats not the plan here and i doubt my next shorthblock will ever be in the car long enough to be worth overdoing.

I dont think the magnumblocks are the best thing since sliced bread but i doubt they are any worse than any LA block i would rather beleive that they might just be better stock considering how machining tolerances has improved over time.

I haven't had the chance to "blueprint" a Magnum block but just from looking at mine the first notable aspect is how TIGHT the piston-to-bore clearances are. Also less casting flash inside the block, cooling passages are cleaner and seem a tad more open (I do know the core plug locations were moved from LA to Magnum). I'm willing to bet the factory decks are much closer to square than LA engines. Also keep in mind most of the Magnum blocks were cast in Mexico, mine has "Hecho En Mexico" cast into the side... might be BS but I've heard Mexican manufacturing and materials are pretty dang good (anyone heard of the Mexican 5.0 Fords?). All the G3 Hemis are made in Mexico btw.
