Will a more quench friendly pistons allow me to run dynamic compression at 8.33 and still use pump gas? I can't imagine it will...
To this end, will these pistons work:

Would it be useful to run the cam at 3-4 degrees retarded to get the dynamic compression down?
Thanks again one and all for the advise! |
These will sure work better than the round dish pistons, but I wonder why the point between the valves on these pistons looks like the end is lower than the top of the piston, not like a full point like the KB pistons. Looks like you would loose a little bit of the quench/squish. These are a little bit cheaper than the KB's, but they are a narrow ring piston so the rings will cost a little more. For my money, I would go with the KB's with the extra .008" compression height. Like msgdsrf said, built with a tight quench you should be ok with 8.33:1 dynamic CR, but it'll likely require premium grade gasoline.
