hi,ive been reading quite a few posts since I have got myself a boat and you seem to have a lot of knowledge and info on these old chryslers, I dont know if you have read my post 55 powerhead 65 leg but I really like to get some help on this ,not sure what the time difference is but could you check my post and maybe give me some advice. seems like there is a lot of readers out there but nobody has been able to help as yet.the marine shops over here dont want to know about these old motors any help would be greatly appreciated thanks
