I have not been able to find the specks at this time.
Here is what's going on at this point. The motor idles good, I Have no problem starting up but when engine speed increases the engine is popping through the carb and showing a loss of power.
I notice the Distributer is wabbling when the enging is running what's next? Motor replacement.
I have located a 6 cylinder chevy engine in a 1975 1/2 ton truck will the engine bolt up to the original trany? I'm not sure what size it is but could it be a 250?
Any Idea on what would work for a motor swap?
Thanks for any help keeping the truck out scrap yard!
You thought I drove a Ford! Where is my cresent wrench, I would like to adjust your thought pattern.
