Honestly, we have maybe a dozen owners here of alloy blocks that don't have any reliability issues and assuming the extra HP is 15-30, which to me is insignificant, then the only reasons you would chose a cast iron block is: a) price, b) you want your Cobra replica to have a vintage block, maybe correctly dated, for "originality" purposes, ridiculous and nonsensical as that concept may be and c) the desire to add 125 lbs for no apparent reason.    |
Hey RK
I'll play, I'm bored to.
1) 15-30hp is about as insignificant as the 5% weight difference you claim, no?
I mean maths is maths, yes?
2) Reliability was never the issue as far as the builders were concerned. Finding quality castings was, as was the risk the builder took on parts of varying quality.
3) Just to continue your rule of threes from earlier in the thread. The "chatter" you refer to in this thread is mostly you and I, and last I checked we both were happy with our alloy blocks.
Enjoy...
