Want to do some up grades on the stroker in the Duster, heres the current set up

Stroked 360 with 4" forged crank
H beam rods
J E forged pistons
Balanced with zero deck
Out of the box Eddie heads
Crane Gold 1.5 rockers
Mopar Purple Cam 528, Add Dur 284, Dur @ 50 241, Lob sep 112
Mallory MSD ingnition
Headers are Hedman running through a 2 1/2 twin with Edelbrock mufflers
Edlebrock STR 1-2 cross ram with 450 Holleys with rear metering plates fitted, main jets 64, secondary jets 63, timing is 33 deg, rev limited at 6150.

Running 727 full manual reverse patan with 11" stall set at 3500, rear end is 8.75 with true-trac 3.91
Weight on the Duster is 3150
Max power at rear wheels is just shy of 300, torque is just over 400NM

This car see's street & strip duty & I feel there is more in it. I know the extuast is one area, I don't want to change the inlet as you dont see them in Oz at all.

Would I get an addvantage in up grading to TTI headers, 1.6 rockers & a smaller converter something along the line of 8"?

Fact is that you have a decently matched combo, as in any larger of this or that and you'd have a domino effect of necessitated changes.

The exhaust isnt the ideal, but for the cams rpm/cid...its actually making the cut.
The heads have more in them, change the cam and the exhaust yes tti would be better and a 3'' pipes w/X over
In that order you will feel more diff in power increase than just doing the exh and leaving the rest.

as for better track performance, there are better convertors...but the stall is actually on the mark for what you are doing in street time driving, i wouldnt want any more stall on the street.

side note, i would use that .528 for mildly modified iron and or streeet auto stroker, but for a heavily modded iron or peformance after market race iron or aluminum head i would be picking a cam for what you are doing in the 250's @.050 dur /284-288 adv and a lot more lift say in the mid high .500's
