Jamo: There is no way the weight difference is 200lbs. You're right what I heard was hearsay. But aren't you relying on hearsay also. Where did you get your hearsay from?
The weight distribution on an original 427 Cobra as I remember is damn near 50/50. Thats with an iron block. If you change the origninal specs aren't you changing the weight distrubution (not that any car you drive will have a 50/50 weight distribution
)
One friend, Candido Duran has his 427 stroked to 454. The other has a staight 427 with aluminum block and heads. The former runs slightly hotter than mine the latter runs substantially hotter. Beats the $hit out of me why. Some things you just can't explain. My engine runs consistantly 170 to 180 regardless of temp. In traffic in August it will go to 185 to 190. Why? Maybe its because I'm special
5000hp? Blowing apart? How many races do those blocks run??? One season if that??
The 427 SO was designed for endurance with high rpms. Iron has an advantage over aluminum when it comes to endurance and wear. Doesn't it????
Maybe the new block oils better. Ok. The original oils fine.
The new 427 aluminum is an awesome peice. The fact it has a CSX number is neat too. Adds value. IMHO.
The original 427 Cobras had original FE 427s. The original FE's that were used then didn't have CSX numbers. Did they? Can we say NO? The CSX # was on the chasis. Just like today. No diference.
While the good ole' FE block may be a museum peice, if you blow the block in an orig or new aluminum block your screwed. Same difference. No difference.
There are some valid reasons to go with a new aluminum block. You can't find a original 427FE in good conditon at a reasonable price or you already bought the aluminum block.
Either block will serve well.
Jeff: YES. I do have a CD and Amp. Both are hidden to preserve the aesthetics of course.
BTW. I'm never wrong.
BTW again. I just went back and read the original question of this thread. Even an over priced, rusty, 40 year old block wins the voter preference by a landslide. Can you imagine if the original FE was in mint condition, NOS or a mint full race NASCAR 427SO short block? It wouldn't even be a contest.
Jamo, you weren't one of the misguided 6.7% were you????
