My question is this motor I have is supposed to have 30k on it and come out of a lincoln. If I clean up the d3 heads and swap the cam can this motors internals take a 175-200 hit. The tune up will be good so other than that will the motor take it?

Car rods arent as strong as truck/SCJ rods, but as long as the tune is good and you watch the RPM you wil be fine.

I would limit it to 6500 personally, but I'm sure there are others that would push them further.

So what is the death of the rods to many RPM's or to much power?

Either plus detonation.

I don't know that there is a magic number, probly more af an area where your walking the edge. Your tune will be key. Some people can break a anvil with a rubber mallet, and some can make junk last forever. 6500 is probably where I'd call it quits on a passenger car rod, but like I said I'm sure others have pushed harder.

I have been 7500 on stock rods albeit truck rods with upgraded bolts and alot of prep work. When I did that motor a cheap aftermarket rod was $700 but now their are decent I-beams for ~$350 which is about what all the work that went into them would run.

Nitrous on a stock longblock Empty I know the common feeling is that truck rods are stronger

but it has been my experience that the rods usually break up towards the small end and not where the two halves are bolted together. I am not a fan of them but I would think that in most instances they will hold 150 hp shot for a while anyway. Quite a few years ago a friend of mine was runing a large galaxy with a 460 with over a 100,000 miles on it and he said it held up fine. I think he was spraying 150 or slightly less.
