Wondering how high you guys have gone on pump gas on our old 8 valvers?

it depends on how much timing you pull out of it,is octane booster permitted?

If you can get it at a normal gas station, then yes, it is.

your 1327 runs with octane boost doesnt it wireman?

yeah but its a special homemade formula my dad makes for me,that stuff you buy at parts store is pretty pedestrian grade as he puts it!its about 12.5:1-13:1,same thing with the 1197 motor that came out of my z1 i had to run the best pump gas i could get with some of his secret formula and still retard timing a little:S

my Honda CB1 is 11.5:1 stock.

have some 13.5 76mm gas ported kz pistons and rings that I bought to run in a J motor but have shied away from bulding with them, mainly because it seems a waste. if anyone is interested in swap, I could use some 73mm 10.5 or 11.5 'J' pistons and rings.
