I'm looking for an engine builder near Seattle that can put together my 261 stroker. I have all the parts. Block is pretty much ready to go. Any leads are appreciated! | | | | | Joined: Jan 2019 Posts: 2,242 Herder of Cats, Goats, and Sheep (moderator) | | Herder of Cats, Goats, and Sheep (moderator) Joined: Jan 2019 Posts: 2,242 | Potentially stupid question: why not do it yourself? If the block is ready to go, the rest should be doable with normal shop tools? | | | | | Joined: Jun 2011 Posts: 5,096 Crusing in the Passing Lane | | Crusing in the Passing Lane Joined: Jun 2011 Posts: 5,096 | How did you get a stroker on a 261?

The old saying is even more applicable today. If you want it done right, do it yourself. Guys on this site could probably talk you through each step on this forum.

I'm a small business owner and have a full time job. My original builder is back on track. He's a reputable inline 6 specialist who has done this for a living for decades. I have more faith in him than me for sure. Also, I'd rather drive/use my truck sooner than later with my limited time. I will be adding everything to the block and head once it's built. This is my second go around. My 1st block suffered a cracked cylinder wall after 2 days of driving. | | |
