Hey D13, you know, thats an interesting idea. I started that engine again today and its sounds great! It started one the first try. Can hardly wait to get it all together to install in my truck. The thing is that my truck is a half ton but also a 4x4. I know from reading about the older trucks when I was much younger that they did put the 230 in the 4x4 until the mid 60s along with the 292 stump puller before the 250 came out in 66'. Thats why I was wondering if it would be enough power to run it ok. Not looking for blinding speed anyway. I do need enough power to climb some passes but with that kind of compression since it evidentally had a rebuild not too long ago and with 3.73 rears it might not be too bad after all. Am thinking of making it a 250 with a crank change and some balancing and headwork. Then it should good enough for me. I have had 4.3s and love them but nothing like the sound or purr of an inline and better low end torque per cu.in too. The 230 engine idles super smooth and no flat spot when throttling it either. So a 4.3 ECM may work? Hmmmm. Something to think about. As you mentioned I have 90% of what I need for that. I will install an HEI ignition on it, one for a 4.3 I don't think will fit. If it did or I could modify one to fit it, then it could be controlled by the ECM to know when to fire the injector. I'm hoping to pull the six from the van this week. I need an engine hoist to rent for the job. Been awhile since I pulled an engine. I hope it won't be too much work. Just have to figure out which motor mounts I need for it. Then the exhaust which is on the correct side for a six on the truck. Just have to figure out how to bring down the manifold pipe to the rest of the system. A challenge for sure but it will be done. I'm determined to do it and I know I'll like the mpg savings and more room under the hood. Simple as apple pie to work on. Thanks for your input. Feel free to share with me your ideas. Thanks again.
