They are shorter front-to-back, but I doubt you could find one of those manifolds either, and the blower would look too small.

If the blower doesn't work out for you, the 2X4 setups are pretty common, and with an imaginative fiber glass scopp, it could look wild! You could even hide a large air cleaner inside. An easier "look" would be the scoops that look like the old hilborn upright from the mid sixties, but fit 2X4s.

BTW, You can machine a 454 crank to fit into that block. It becomes a "stroker crank" for the '09. It takes a lot of work, but could boost cubic inches a lot.

Some other parts will interchange from small and big block Chevy's.
