So by all means, I'm not very knowledgeable when it comes to engines as I haven't delved into that subject to much in my personal studies. I asked a couple months ago about boring a 273 to 340 specs and you guys said it couldn't/shouldn't be done due to the webbing between the cylinder walls. Simply, there's not enough meat. However, IIRC, you guys said the 273 and 318 blocks were similar. So theoretically speaking, if I really wanted to, I could buy a 390 stroker kit, bore out the 273, and purchase heads, intake, and carb compatible with the 318 and have myself an engine?
