Nice. The 400 seems to be an overlooked engine, but I guess a lot of people have built them up to a lot of horsepower.

can confirm that you can make really good power with a 400 and the right combo of parts.

though i have the 73~76 spool mount K, the TTI headers fit a good as you can hope in the bay of my '68
