Got my junkyard magnum motor in the 11s!
LXguy, congrats! awesome, again.
To all you who guys jockin the magnum...
tell me, what is different about the crank and rods?
tell me 'those who have sonic tested' are those magnum cylinders thicker? or thinner..
Now, The magnum block has 3 spider bosses as where it used a .390'ish lift HYD roller cam huh? Do you think he's running that stock cam? NO!!!!!!!!!!!!
I bet he had to buy a 'new roller cam' and where 'IF' he wanted, he could use the stock HYD lifters, 'don't know about havin any cam warranty with'em' but he still could...
I do know that if he does...he has commited to a hyd roller cam, no solid unless he buys NEW LIFTERS AND CAM , so that is somewhat of a compromise....
the heads... ha ha not factory 'magnum stuff' , more like after market heads based on magnum valve train and the massive pinch from the enlarged push rod hole, thats an improvement???
all you guys thinking your gonna go out and get yourself a magnum and be ahead of the '360' la, you're kiddin yourself, maybe in stock form and from purely a stock 2 barrel stand point, and thats do to the tiny roller cam and fuel injection.
No factory magnum head flows more on the intake side than the 2.02 340 x/J head, and don't tell me **** about the port volume and air speed cause I have the heads and the port volume #'s in front of me and the magnum has no advantage in the performance world , unless you consider the air speed from that MASSIVE pinch a advantage...
Other than the exhaust port flowing a whole 2 cfm more 'as stock' and doing it through less volume, which btw would suck on a stroker that needs spent gas to get the fk outta the way with back pressure taking the 'back seat' with extra volume necessary while pushing the R's, The magnum head was a way to save money and put out lesser emissions by means of the closed chamber, funky turbulent toilet swirl ports and fuel injection it is only but a minor improvement but with the expense of cracking/faillig head cores.
BTW when you go racing and the compression go's up, you need not give 2 shts about swirl ports and their turbulence cause the damned piston is sending the signal right fk'n NOW and not just lazily taking it's time like a 8.5.1 pos...
I'm shocked but not surprised to see everyone backwards on this, it's been this way for yrs sadly enough.
And only nowadays AFTER the indy rhs manufacturers have already not learned from the past and are having to recast with LA port windows that don't restrict air...
sorry to hyjack the already hyjacked.
LXguy, again..Right on man!
