Hi there !
I've checked my head cylinders code today. My engine is a 350ci.
I've got a 3998991 on it, from 73. So, what do you think about these head cylinders ? I've not seen so much good on the web, about performance.
What should be the best adjust with a 625 cfm Road demon carb and Hypertech HEI ignition ?
Thanks
