#'s Matching 340 build

i currently have 3 stock manifold vehicles with custom cams
440 with HP manifolds
350 chevy with rams horns in a pickup
250 chevy with through the prop exhaust (replaced 4 cyl Mercruser)
all have appropriately ported heads
the 6 cyl pulled strong to 6500 on the dyno and we chickened out 2bbl marine carb which is required
The 440 has no trouble with 6000 TQ Jones cam 2 series gears in a C body or in the motorhome
both have Isky dual springs
350 has no tach but runs great- has a TQ from a 360 altitude compensator etc
I also built a 383 Superbird stock looking with 440 crank and rods Crower 218 @.050 cam with .525 lift ported stock open chamber heads with 2.14 intake
My plan for the superbird was to max out the head flow at the lowest rpm possible through max rpm
It's a 4 speed and drives great on the street no problem with rpm drop problems, you can short shift it and just drive away from start or excess shifting required
The extra cu inches allowed us to back off on the compression and cam and still have a stronger build than building the 383 which could only max out the heads at higher rpm's
