I don't know if this has been asked yet but how fast do you go with trick flow 240's ?

75 Duster - ladder bar backhalved. Right around 3150lb with driver. 440 .040 over 10.9:1. Mopar .557 cam, TF 240 heads, Victor intake, Proform 850 carb, TTI 1 3/4" headers 727 with 5000 stall convertor, Dana 60 4.56 gears, 31x13 tire. Went a best of 10.49, but typically runs 10.70s. Shift at 6000, go thru traps around 6400.

We all run what we run combo wise with reasons for it but your giving away a bunch there with those good TF heads with that small cam and hdrs, funds allowing I'd stick a .600+ sft in there with min 2" hdrs.
I had a very similar set up chassis wise and ran 10.71@125 at 3250+lbs in my back halved Cuda with 4.88's/32" tyres and a 4800 stall running a 440-6pk 10:1cr stock b/end motor with 265cfm@best 906's and a comp .650" SFT cam and an 850DP with a crappy Team G intake with 2" f/wells, trapped@6600, made very similar hp to what you have unless your running 128+mph and you outflow my heads by 50cfm....just saying as an example.
