What would it take to make 1.44 lbs-ft per cid ?
good heads with high velocity ports,
Yes this is true but right port velocity, and that is the question what is the right velocity ? and most seem to worry about it being too low but as I look at the velocity of available heads it seem to be too high, from what I understand average velocity of 250-310 fps being acceptable range and 260 fps being the ideal and up to 285 fps still being somewhat ideal.
So based of the 260 fps as ideal and the calculations to get there, (I'm not saying this is proven right).
So a 365 with peak hp @ 5500 rpm.
Minimum csa (push rod pinch) 1.825"
Average csa 2.263"
Port cc 184 cc
Port cfm 246 cfm
A 184 cc port seems fairly big for 246 cfm we would expect at least 270-280+ cfm for that size which would bring the velocity up to 290-297 fps which is still acceptable but outside the supposedly ideal.
