Welcome to the stovebolt page. That looks like a good, clean install. I agree 230 or 250, probably 250 due to distributor. Check the stamped serial number for sure. In the picture of the right side there is a clear view directly behind the starter and I do not see a frame crossmember under the bellhousing. How is the rear of the engine/trans assembly mounted. There must be a crossmember under the tail of the trans. What trans does it have?
If you wanted to take some more pictures of your truck, engine, trans, mounting, etc. that would be cool. We all Love pictures!!
And, I have an interest in putting a 292 in my 50 Chevy and need some tech-help on the mounting.

Thanks.
