I have a LQ9 (6.0L), TSP Tsunami Cam, 1 7/8th longtubes into 3.5" dual exhaust, 5k stall converter behind a built th350, spool w/3.73's in an 8.8 with 28in slicks.

Car has gone a best of 7.1, runs consistent 7.2 @ 97mph in 95-100* heat.

I tune with HP Tuners, afr is pretty flat at 12.8:1 across the band, timing is 26-28*. Never been on a dyno.

Trying to figure out my next step, either I can drop ~300 or so on a anti-roll bar to help with my 60' times (consistent 1.6x right now, but car leans over hard onto the passenger side and spins a few feet out of the hole, needs a bar).

But besides the roll bar I need to make more power cheap, thinking about just simply swapping on a set of 243 heads with a valve job.

Any other suggestions for a cheap bang for the buck mod for a cam only 6.0 liter? BTW: this is in a mustang.

 

243's would be the best heads you can get for some cheap power but you could spend a little bit more and do some nitrous for a lot more power

 

A good cylinder head will add a good bit of power. I would really like to see you running something like a PRC 237 or 227 head on it, but if budget is something to consider we offer cnc porting of your cores & milling for a very reasonable price. For $850 you can bolt on roughly 40-50hp!!
