hi all, ok i have a 1966 kombi and am looking to build/buy a stong reliable motor to push it along. i want it to be happy cruizing at 70mph which would be at just over 3000rpm with the current drive line fitted. what would you recommend? there seems to be so many options out there. i'm not after fast acceleration, more into reliabilty and cruizing but dont want no slug either! whats your advice?cheers, dave.
