Re: Onuma's '66 1000 (Lotsa Pics)
Heck, 305 V6 runs fine on 87 octane. The low compression of 7.8.1 really makes these engines almost run on water. Mine runs fine with the E10 blend using 92 octane. Run "sea foam" fuel additive in every tank fill and you'll be fine. A new engine isn't "readily able to take E10/85 blends) if they sat for as long as people let their classics sit then you'd have the same issues. Its your choice all together, but a good running 305E isn't hard to find and can be picked up cheap and they run on low octane just fine. With a good tune up cold starts are easy. Mine starts right up every time with out issue...and the cost to replace a carb is waay less than an injection system. My 2 cents.
Edit: The 305 gets a SOLID mph to.
