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

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.

I used to have 2" hooker fenderwell headers on the car, but than tied the cage to the front frame and the fenderwells wouldn't work so I put on the 1 3/4" TTI I had (At the time I thought they were 1 7/8 so didn't think much of it, but Looking back I should have made the bars tie to the frame so it wouldn't affect the headers, but hind site is 20/20.) I kept the hookers and as a winter project I'm modifying them to fit. Only have to redo tube #7 and #8. Was also going to swap in a .590 cam I have, but don't feel like doing that much work. I'll wait until I freshen up the motor to do that. I'm curious what the headers alone will help pick it up.
