i did a search.. ok, so i have a 4mm stroker with the 795 pistons.the piston is seriously out of the bore(maybe 1/4) which is probably normal. i have custom domes for the noss head, checked them and they clear just fine. i have 35mm pwk's,adj. timing,v-force 3's,billet intakes w/ the reed spacers. my cylinders were ported by r@b it is his aggressive dune port,transfers done and all of that except boost ports.oh yeah i also have cpi small bore pipes. so now we know a little about my engine... what should my timing be? i know i have to run race gas because of the domes i got so i guess i can get a few more than 4 deg's of timing. let me know what you think. don russell
