Well, I have my 305 that's for sale. it has 115000 miles on it and it ran really good before I yanked it. Just want to sell it for a pretty fair price. PM me if you're interested. PS I want to get rid of it
the only thing it needs is 1. a good pressure washer cleaning, 2. valvestem seals, 3, there's a little bit of popcorn in the pushrod valley the needs to be removed.
That's all I know. It's been ans still is a good motor.
