Hi Eddy. I had a disastrous time with Keith black ikon pistons. Mine suffered bad heat expansion so that when cold they banged like hell and eventually caused ring damage. I began to discover that cheap forged pistons not using metals with a low coefficient of expansion are not worth the aggravation. If you must go forged look at JE/probe/mahle. The hypereutectic are actually preferred by real steel in their own enginesThanks Mike - I spoke to Kenny today....and my goodness he can talk! His opinion for the bottom-end was:-
However, I have already had my UN1-013 rebuilt and plan on using it. I'm concerned that the torque from a well-built 347 might be more than is comfortable put through a UN1, and I'd be personally happier with a "piddly little" 302 with a well-balanced bottom end using quality components. I noticed in Real Steel's price list a set of forged +0.030 Icon pistons:-
- 347 stroker based on new Eagle crank (don't bother with a piddly little 302)
- Forged pistons (doesn't trust any cast piston, even hypereutectic alloy)
- Use new rods - by the time old rods have been re-worked for ARP fasteners you might as well have bought new rods
CROWN F/T -4.8
With a weight of 565g, they're a lot lighter than the +0.030 KB pistons (703g) and are designed for use with 5.4" rods, potentially allowing me to build a long-rod 306ci with a zero-balance factor (I haven't finished doing the maths to work out if this is possible).
I might cross-post this to the "Engines" subforum for people's views.
Hi NeilI used my engine hoist to lift my chassis and turn it over for riveting on my aluminum panels. What aluminum alloy and what rivets are you using?
