What intake manifold do you have? The marine hemis
came in 3 flavors - two 1-bbls, one 4-bbl and two 4-bbls.
The two 1-bbl. setup used Ball & Ball 1 bbl carbs similar
to those used on slant-6s. The single and dual 4-bbl
engines used Carter WCFBs that flowed about 350 cfm
each. If you have the two 1-bbl intake, I'd probably swap
it for a single 4-bbl intake although you could probably, with
a bit of work, get a pair of early slant 6 carbs to work on it.
For a single four or dual quad intake you could use 500 cfm
Carter AFBs or the equivelent Eldelbrock knockoffs. On a
a single 4-bbl intake, an adaptor plate and a 390 cfm Holley
(list number 0-8007) or a 550, 570 or 600 cfm Holley
(List numbers 1849-1, 0-80570 and 1850-5) would be
reasonable choices too. No mattter what carb (or carbs)
you adapt to this engine, with anything non-stock,
you're going to have to play around with the jetting and
modify or fabricate throttle linkage and choke set-up.
