Trick Flow SBM Heads

Not quite apples to apples, but close.... My Barracuda has a very similar setup but with ported Edelbrocks:
3250lbs, 727, same cam (Hughes 264-268), 13:1 compression
750carb, Victor intake, 8" converter, 1 3/4 headers.

Best of 10.19 @ 130.5mph
So I assume trickflows would be about a 10K investment at this point...
Assuming you get your half second bump to 9.69... now you're consistently below 10 seconds and of course your recertification of everything every two years roll cage etc.... Added stress to everything..
I couldn't afford to race at the mid 11 second level let alone below 10 seconds...
