Here's my unstroked combo..

383 Bored 30 thou - Flat Tops-Balanced Bottom End - Comp Ratio around 9.5 - Mopar Purple 484/484 Hydraulic Cam
Unported 516 Heads-2.14/1.80 valves, Comp Springs, Roller Rockers
Eddy TM6 single plane intake and old (4479) Holley 750 D/P
MSD Streetfire Box and standard Chrysler Elec Dizzy and MSD 2 Coil
T/Flite 727, 3,000 stall, 4.10 gears

Ran 13.7 (@103mph) at Sydney Dragway a couple of weeks ago in extreme heat. Needs some sorting out as should be running quicker.

Here's pic from burnout comp.. It's been nicknamed THE TAXI!

66 - that reminds me of my Newport... I bought a '69 300 to replace it and that's in the weeds until I get to it. But I have some pics like that. My Dad came home one night after being at a cookout accross the street and his first words were "Do you have any idea how ******* annoying that car is??!!!" Dad never swore but had some gin in him... I had been tuning the car (from a dead stop) out in the street...lol.

The block is date coded: 12/26/67 383 bored .030" over with flat tops. Intake is an Edelbrock Torker 383 with a 850cfm Holley center squirter built in the fourth week of June 1969.
Heads are 906 with hardened seats and the large valves and no porting.
Cam is a Hamburger 509 lift 292 dur.
Ignition is MOPAR Performance distributer, 8mm wires, Blaster II coil, and a 6AL box chipped at 6800rpm. (roughly 6200rpm shifts)
Headers are custom made 2" primaries, 3 1/2" collectors, 3" exhaust pipes and Flowmasters.
The best she has done in the 1/4 is a 13.20 since the car was severely traction challenged last time to the strip, and the carburetor at the time was not so good 750cfm Edelbrock with 235/70/15 tire. The traction problem has been since rectified but have not been back to the track.

Oh ya the best part about this car is that it is stupid fun to drive!!!!

Who built your custom headers?

68 383 non HP block bored .030. Stock std steel crank. Stock rods reworked with ARP bolts and KB400 domed pistons JE low tension rings. Block zero decked. Reciprocating assembly balanced. Lunasty solid flat tappet, .540, .563 261, 271 @ .050 on a 108.

Going with ported 516s and adding 2.14 and 1.81 valves. Compression will end up 10.4:1. Topped off with an old Eddy 383 Torker and a Holley 950 VS three barrel. Don't know what it runs like as it's still a work in progress, but that's the recipe.

this is what I`d do , but w/ alum. heads. Iron heads at that comp. will more than likely need "good" gas , won`t it ??
 
Another thread up from the past. Ok, I'll bite!
The year was 1975 and I had a 1969 383 $ speed Roadrunner that I raced. It had a stock stroke .030 over block with stock crank, stock rods and bolts with 12;1 forged pistons. Stock heads and valve sizes, no porting. Used all the stock stamped steel rockers too.
The cam was a hydraulic flat tappet by Crane, I don't remember the specs on it but it had a pretty radical idle for a street driven car. Topped with a 383 torquer intake with a 750 double pumper.
It had a dual point distributor, remember those?
Hooker race headers with no exhaust mufflers.
The 8 3/4 had 4:56 gears and goodyear 9 inch slicks.
The best pass it ran was a 12:27 at 115. I thought it was pretty fast for what it was.

With that cam, plus the quench, it's run on super.......maybe on 89.
 
about 5 yrs ago, 1969 RR, 383, trw pistons, solid cam, 254/267, .540 lift, 5.13 gears and 28.5 x 10.5 slicks 4500 conv, shifted at 7200 rpm. ran 11.55 @ 116 MPH. and 906 heads.
 
I heard the 383’s liked to rev more than the 440. I would guess a 400 would be the same,,,with good pistons of course.
 
Hmm.......the throttle position has always determined where each of my engines has 'liked' to rev to. It's always been me to decide what my engine liked and I've left my engine's feelings out of it.
