Exactly, who wants a 8-8.5 to 1 stroker motor? I pointed out an Olds 350 of all things with 9 to 1 with very good vacuum, I believe 19" with being able to run a 89 according to the builder. I say more like 87 if vacuum advance is limited to about 20 degrees with the usual 20 base and 16 to 18 mechanical coming in fairly quickly, that the Olds V8 likes. Not everyone wants or can afford a 10+ to 1 aluminum head motor. I get not being absolutely stuck, having to run premium and being on the ragged edge. Another big part of getting rid of factory pistons and rods is they are weak and outdated. Mahle is now using 1mm ring packs, others use much less drag with 1.5mm/1/16" rings vs our power robbing 5/16" factory rings on weak cast pistons and aftermarket rods are way lighter and twice the strength of stock rods.
