What's the appeal of an aluminum engine block?

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...

Oh Dimis,

1. I could re-jet and tune my carb on a chassis dyno and get 15-30 HP. Where would I drop 125lbs with my Kirkham?

2. Yea, reliability is/was a concern. Somewhere in the last 15 or so pages somebody (not me) mentioned "power, reliability and quality." That wasn't me. And the other complaint was the alloy block casting was flexing, expanding, contracting and popping at the seams, whereas the cast iron block was rock steady and never leaks.

3. My rule of threes? I think it was Patrick and others talking in threes. I was only pointing out the anomaly.
