$ Building a Slant 6 for performance
Which heads? BTW I want to build a 262 /6 I won't be the first.
Which heads? ANY small block heads that are not priced astronomically.
If you want a fast small block V8 that is capable of 2+ hp per cubic inch (normally-aspirated), you'd better be ready to spend a LOT of money on cylinder heads. That goes double for a 440 cubic inch, stroker small block.
The only slant six cylinder head we have to work with (except for the really hard-to-obtain "Argentina" head,) was designed for a 170 cubic inch motor. Because of the slant six's small bores, and small bore-center spacing, there's not much room in the combustion chamber for very big valves. That head is never going to breathe very well; why you'd you want to make the problem even worse, by creating a 262 cubic inch reciprocating assembly is hard to understand.
If you just want a lot of power, turbocharge a 225; there are a couple of them running that make 500+ horsepower.
Of course, you could build a 262 and turbocharge IT, but engine longivity might be a problem, then.
Just sayin'...
