Dakota 'shorties' in early A ??
The other advantage is the W2 intake port is very strong in the 4200-6800 rpm range on a 340" motor, proportionally that will be roughly 3250-5400 on a long 4.25 stoke motor. A W2 is not very dependent on "fifth cycle" scavenging/overlap to keep the cylinders charged. This cam (and the motor combination doesnt require) doesnt have a lot of effective overlap for the dize of the motor (109 lobe spread) do I think the torque eill comr on fast and hard and I'll shift at a relatively low RPM andvlet the syroke and piston velocity do the work ( much like a standard port 440 rb or a buick 455).
port velocity and broad high ve will be the key, thats why i think thr manifolds will still work well because I'll.be shifting before the ve drops off. momentum should make it quick....well.that snd the relatively light weight if the early a body.
it should be fun
