i agree totally im not building a race engine just trying to get a better tork range and as i said 10.5 to one was just a guess there not much info on deck hiegts when i get the bottom end together with the new pistons i will have a better idea of compression ratio i dont mind using high octane pump fuel in it at the end of the day it will still be cheaper than running a 2 strokeand if u no 2 stroke engines there pritty flat on low rpm so i cant see how a mild solid cam will afect bottom end power all the mods r to increase strenth ans reliablitiy read a few forum post on other site and some guys r having oroblems with bending pushrods too ill put some picks up of the heads and the bad condition of the vavle tips and rockers and also i read that the blocks were made by volvo
no one has yet told me if 3.7 use flat tops pistons
