current combo- 347ci, 8.5:1 probes, p1sc/ 12lb pulley, gt40x's, e-cam, 1.7s, gt40 upper/ lower, 42 lbers, art carr aode, aluminum d/s, 3.73 cogs

Best so far 11.95 at 113. Traction was there, rev limiter at top end was also there in 3rd, and a/f ratio was dialed in perfect. Cannot launch any higher than 1800. whats going to be needed to hit 10s? im swapping to a g force tranny this winter.

60 fts - 1.80 flat
red line- 6400 rpm (tweecer)
tuning- tweecer r/t
mph- im hitting the red line in 3rd, im not going to even try using the aode overdrive, this combined with my converter launching woes im switching to a stick

i thought the larger 3 core i/c, a 14lb pulley, head and intake porting, 50lb injectors, tubular k-member, a-arms & coil overs, and a new cam might do the job combined with the stick and a taller tire with skinnies in the front (still full size street tires up front)

How bout a better h/i combo? TW or AFR 185's with a better flowing intake.

Something definitely doesn't sound right. Why can't you launch higher than 1800? That is what appears to be your biggest limitation to me as you will need to laucnh harder to pull some better 60's, although you will need a bit more trap speed to see 10's. 113 is good for around a 11.7 or so if conditions are right. What tires are you running? Even with 3.73's and a standard 26" high tire you should NOT be hitting the limiter set at 6400 with only a 113mph trap speed. Is the converter slipping that much on you? What is the 1/8th mile ET and MPH?

Was the car ever dyno'd? What rpm are you shifting/letting it shift at?

A bunch of these suggestions are going to do nothing - the car flat out is messed up. You could bolt E6 heads to a stock 302 block, zing it off the rev limiter with a blower and go 11's.

Porting the heads is a waste. You're moving into a largely diminishing return. Same with the intake - if you need to port a street-style intake, you'd probably be better off with a different manifold all together.

This IS NOT a 302. In theory it can use the same parts, but, it really cannot from a performance standpoint. Those heads are for a 302, the cam would run good in a carb'd N/A 289, and the manifold is just enough for a 302. Your results (since everyone thinks they're bad) don't surprise me too much, especially with the automatic. 11.70's would be surprising (to me, anyway).

This is what I'd do....

1) Sell the top-end for bigger/better used stuff.
2) 3000-3200 10" lock-up converter.
3) Transbrake
4) Slicks

Like Joe said, the parts are VERY small. But the big problem is you're hitting the limiter. You need to raise that. How was your tune? Timing? A/f ratio? Fu ck porting this stuff, you need to fix that rev limiter and verify your tune. The boost will help 'fix' your restrictions.
