Well, I've apparently got way to much into my motor to be as slow as it is, but here's my entire combo that has gone 12.39 @ 110.
1967 Plymouth Satellite, Full interior, 3770 lbs with me in it. 400 block, .040 over Forged 413 RB crank, (452 cubes) Scat H-beam Rods KB Icon forged pistons - 10.25:1 Mahle plasma-moly rings (bobweight: 2314) MP windage tray OTB Stealth heads with 10* locks & retainers, & Engle double valve springs (350 lb. open) Engle KV-3 solid flat tappet cam: square 252* @.050; .573 lift; 109* cl, installed straight up. Performer RPM intake Holley 830 cfm DP jetted 78f 84r MSD Digital 6+ ignition w/ Mallory Mag-breakerless distributor - 36* total in at 3k. Hooker Comp 1-7/8" headers to 3" dumps, down to 2-1/4" full exhaust with Flowmaster 40's ACC 10" 3500 rpm converter 727 with Transgo Stage 2 kit 8-3/4" w/ 3.91:1 gears; sure grip. Stock suspension with SSM lift bars, and Summit adjustable shocks CE bolt in Frame connectors, welded in. Hand-me-down 28x9x14 slicks mounted on 14x6 rims.
I've made 10 passes and haven't really done anything except mess with the jetting a little. I love the car, and am proud of the motor I built for right at 5-grand total. I am plenty confident that there's more in it, But I'm frustrated with what I see here..... i.e.: a lot of guys going WAY faster than me, with way less motor. I think that a set of better tires on the right rims will help a little, as its pretty skatey on the current slicks.
I think my combo SHOULD be somewhere near the 11.70's. I figure I'll have to make about 114mph to get there though.
You and I almost have the same set up. This is what I have and my best is an 11.80 @ 113(and change), 1.62 60', .452 r/t.
I got a 67 Coronet, all steel, full interior. 400 stroked to 470, 10.8:1, Diamond pistons, Manley Rods, 727 trans with a 2800 PTC, 4.10 dana spool, Eddy RPM heads OOTB, RPM intake, 830 Quik Fuel carb, Voodoo cam 60304, MSD, 325x50x15's M/T drag radials, TTI 1 7/8" primaries, 3" to rear bumper, summit 90/10's front, stock shocks rear, frame connectors welded in.
You should easily be in the verrrrry low 12's to high 11's with your car before tuning it. I didn't do much to get out of a 12.10 @ 110ish to my new best - basically put on better tires, shocks, and had my trans rebuilt (it definitely had seen it's day) and that was it. I was doing backflips for hours after hitting my first 11 second 1/4. And then the fun began...
The only thing I could think of would be the tires - you said hand me downs... I improved quite a bit with more footprint from a 275 to the 325s I have now... but that also meant I mini tubbed and moved the springs in. How are your 60' times? Spinning? Traction issues? Take photos or a video of your launches to see how your car reacts? I'll be the first to admit, I am always learning AND, what I have learned, I am willing to shed some insight as well. That's what makes Moparts so awesome.
Best of luck to you and your project!!
Dave

Want to hear cheap. I built a 71 440 from a Chrysler 300 that had out of round cylinders, one in particular was .017 out. The owner was cheap and didn't want to bore it. I tanked the block, put in new cam bushings, cleaned up the crank, rods and pistons, put everything back as is with new rings, bearings etc., put in a used 484 cam I had sitting around from a previous engine, had the heads milled .040 to bring compression up from the factory 9 to 1., installed a used eddy performer with a 750 holley. rebuilt 727 with a 3000 converter and 3.91 gears in his 71 Charger which has a worn out suspension. The engine is now 10 years old and has excessive wear on # 2 cyl and the engine smokes on that bank but he is happy with it and it is still going. He drives it 40 miles to the track and back home and it runs consistent 12.70s at 106 mph. This is on an engine 10 yrs old with 70 percent leakdown on # 2 cyl. Imagine what it could run rebored with fresh heads and balanced. This is proof it doesn't take much to get a mopar running.
