it's all relative..

especially when you compare what comes stock in a sb dodge as compared to a sb chevy or ford, pontiac etc...

mopar=shaft mount, early steel cranks, 18* valve angle, long rods, 1.84 rod ratio...beefy mains..etc...

when you 'start out ahead' you've already saved over the seemingly cheaper sbc,sbf,sbp because when you go race...you end up having to replace most of the parts to keep up, like fixing studs, buying heads, longer rods that don't twist, and a roller cam/or inlarging lifter bores to mopar size [.904] to keep up.
Don't get me wrong, chevys compete every where and hold records, but it wasn't with your old suburban motor, well maybe 'the block', but thats it.

One of the best 4 barrel iron intakes comes from a 74 360- it has a raised plenum and will work in the higher rpm's.
'71 was the last year for 2.02 sb heads.
fwiw 2.02 sbm head intake flows 215-225cfm stock, 1.88 heads flow 195-205cfm stock.

I have home ported J heads on my stroker 410 that flow
198@.300
246@.400-
270@.500-
284 @.530
thats with an 11/32 undercut 2.02 intake from ferrea, nothing special either.
