Cut off line for Cast and stock internals

Thanks, I appreciate the info and dyno sheet.

I'm kind of familiar with Water/Methanol Injection, since I was looking into it (briefly) for my '84 Turbo Diesel D50 pickup. But I'm curious, are there any negatives to running it on a Street driven Gas Engine? Abnormal wear, Potential other issues?

Of course when I say street driven... The 340 in question might see 10,000 miles in 30 years, if that. As an Example, I use my '74 Duster as a Daily Driver in the Summer (switching to my truck when it rains...that car is a death wish in the rain) And I've been driving it since 2007... In 2007 it had 103,103 miles on it. When I parked it for the Winter about a month ago, it had 103,890 miles on it.

4 Years of driving it and it has yet to reach a thousand miles of use.
