As for my 7500 rpm limit, at this stage I am purely going on a guess of what my heads and intake will flow. The intake needs to be ported, but if I can get both intake and heads to support over 400cfm flow, then I will choose a cam that will use the flow. If the potential hp will peak near or over 8000rpm, then I will use aluminium rods.
Sounds like the undersized rods might be the way to go. When it comes time to order, I will be in touch with you Keith.
How much would a set of 6.7" (or 6.680") aluminium rods expand with an oil temp of around 200F? As I mentioned above, my pistons have a deck clearance height of 0.001" with a 6.7" rod. So if I use a 0.020" undersize aluminium rod with a 0.039" head gasket, once the engine is warm, will I have close to 0.040" quench height?
