Any advice on my 440 recipe?
I think Summit has a typo on the 424P piston CH, everywhere else shows it as 1.912”. I measured it at 1.945” and at .19685” piston to deck, putting me at 7.32:1 currently. Best piston I could find to get me into the 9:xx range is this dome type from Speed Pro. Puts me at 9.29:1 with stock 90cc heads or 10.11cc if I end up eventually going with 80cc Stealth heads.
I may go this route and give Comp a call Monday. But still exploring all options.
Thanks for all the info, still learning lots every day.
