heres one for the budget racers like me. What's the fastest you have gone with a stock piston stock headed? Post what you have done to your combination and how fast it went.

Mine stock size 360 reringed stock head stock intake 4.10s. Ran a 14.78 last weekend at 93 mph
 
Kind of a vague question. What all are you trying to do here - race the car without doing anything to the stock configuration and see how fast it will go?

There are guys in the the 10s with stock pitons and heads but going that fast obviously depends on the rest of the combo. There was one guy on Moparts a while back who went in the 9s with some 'stock' parts in his 340.

Is that 14.78 ET with a stock cam? Do you have headers? What about the carb, intake or ignition? Any chassis modifications? Slicks or street tires?
 
Defitnetly lay out your engine combo when you post up! Equiring minds want to know!

Rmchrgr; I think this line of thinking is take your stock long block and give it go fast parts kind of thread.
 
I got nothing vague at all. Engines using stock, unaltered heads with stock type pistons is what I got. So anything else I assume, since it was not mentioned can be changed.
 
Ok, just to give an example.

I ran my '71 Dart down the track about 7-8 years ago. Bone stock 318 2bbl, exhaust manifolds with dual exhaust, column shifted 904, 7 1/4" rear with 2.94 open diff., 14" street tires. 17.67 @ 76 mph.
 
Ok let me re phrase. Stock internals (Pistons, crank, ect) and factory iron heads. Stock long block. Can be bored but if you slap in some kieth black Pistons with a different compression height it doesn't count. Did that clear it up?

Mine is a 1980 reringed 360 stock long block. Stock cast iron manifold. Holley 600 vac secondary carb. Gutted out d150 with a 4.10 spooled 8 3/4 on 29 inch slicks. Weighs 3300 without me in it. Stock rockers and push rods. Comp 274deh cam. 727 with a trans go full manual shift kit.
14.78 at 93 mph started the day out with a 15.03 run
 
The 340 in my 68 dart has stock replacement pistons in it, stock X heads that looked to be opened up a little near the valve seat with some kind of machining but no porting. I did a rering and bearing, installed a small 235 @.50 solid cam with around .480 lift, 273 adjustable rockers, air gap intake, holley 750 dp, stock mopar electronic ignition, cheap flow tech headers, 3800 stall converter, 410 rear, ran best of 12.90's @ 105.
 
Stone stock 1965 383, fresh bearings stock 516 heads, 528 Mopar cam, street dominator intake, 13/4 headers, 850 Holley

car was a 1965 coronet 3500lb with me
727 with 4500 converter, 275 drag radial and 4.56 gears went 7.96 1/8 and 12.60 1/4
 
12.54 @ 106 mph 1/4 mile

My junk yard 318:
stock cast crank
273 rod
cast pistons
360 heads, milled alot
Comp XTQ281S-6 cam
Eddy Torquer II intake
750 DP Holley
4.88 gears, 904, 4000 something stall converter 275 M/T drag radials
 
I've gone 13.30's with a 360 stock head, stock cast intake with a TQ, mild MP cam (.474 lift), stock torque converter and 3.91's in a 3300 lb car. It was .040 over, but not high compression.

Got it.

Car is slow for what it is. Sounds like the truck is fighting itself. That thing should be in the 12s easily. if you are dead set on staying with the combo as-is, you need to start verifying stuff.

Make sure the throttle is opening all the way and the floats are set correctly. Can you verify you are not running out of fuel? Was the cam degreed? Valve springs correct for the application?

Now the tuning questions will start - timing especially. There is definitely power to be had with timing and carb adjustments. Make sure the plugs are the correct heat range and the secondary side of the ignition is all in good order.

Make sure it's aligned well enough so the tires are not pushing. Check the pinion angle, make sure it's not fighting the launch. Tire pressure, shocks, front end travel... ET is not all in the motor.

Stock converter? Could be slipping badly.

That's why I said it was vague, could be so many things it's hard to pin down an exact answer. Someone else with stock internals could easily be 1-2 seconds faster and you would never know why until you start delving into the details.
 
69 Dart, 3.23 SG with 4-speed and 7X27" cheater slicks, drum brakes and manual steering.
reringed 68 340 with X heads, 1-3/4" headers with 12" collector extensions, LD340 with 3310(750 vac sec),MP electronic ignition with chrome box,MP 484/284 cam with CompCams springs/retainers. car ran 13.18 at 108 going thru the traps in 3rd gear.

I ran 15.30's with a 1989 Dodge D150, bone stock 360 factory throttle body injected, factory manifolds with single exhaust and factory 3.21 gears and 28" tire. I eliminated the cat and put a turbo muffler that dumped before the rear axle.
 
I appreciate the honest post here! I was thinking I was doing pretty good last weekend Best I've ran so far but then I'm seeing there is deffinately more to be had lol.

But to answer your questions and I think a big problem is the converter. Bought it used and was supposed to be 3500 but not behind my motor I launch at 2200 max otherwise she starts pushing through the brakes. 2nd problem 4.10 gears with a 29 inch tire I'm running out of steam at about 4500 - 5000 in third gear and started dragging 2nd out to 6000 rpm before shifting.

Timing is a reman carquest distributor set at 14 initial and about 36 total. Currently have RN14YCs in it I always ran 12s before this set. Pinion angle if I remember right was 0* difference between tailshaft ujoint and rear. Open headers with the collectors bolted up. I do need to get it aligned I set toe at home with a tape and set caster at home also, all I can say about it is it goes straight and doesn't wonder. Haven't had enough track time to notice wear on front tires.

This weekend I leaned it out enough to go up one jet size and run faster so I'm thinking I'm close. The race last weekend was something different that they took your fastest qualifying pass and took off .10 from it for your dial and I lost due to reaction time on a pro tree. Stock mopar ignition all used stuff that I had laying around. Valve springs match the cam, cam was not degreed. Carb is opening all the way. Shocks up front are s10 and new this season. Rears are 30 year old factory shocks that you can see the oil running out of the seal (I said budget racers didn't I)

If you have any suggestions other than start over I'm all ears and not easily offended.
 
Sounds like you are not a total rookie.

I'd say the cam not being degreed is a big one since you could be leaving some power on the table. That would also change your tuning parameters right from the start. It's likely close but if you decide to delve into it and see where it's at, you might find it responds differently.

I would also try to bump up the initial some. How quick does the timing come in? You will probably need to limit the mechanical some though so it's a balancing act.

Open headers should help, at least it's not breathing through manifolds! But, lack of back pressure may be an issue with the stock intake and small carb, i.e., reversion with too much air. Carb might be too small for WOT. Can you try a larger carb to see if it helps?

Small blocks need gears for sure. 4.10 gear should be OK but you are correct in that the tire might be too tall. Where do you shift it at? I'm guessing under 6,000 rpm.
 
The light is set a 5800 seams to have gotten my best times shifting around there. Unfortunately I only have 2 other 600 carbs on hand. Only have one more race I'm going to attend this year. This winter unless I fall into some money I'll degree the cam and thinking about milling the heads .060 and smoothing out the runners and running rocker shims from Mancini. Was also planning on picking up a 6al box and blaster coil and edelbrock performer rpm manifold if I find one for cheap. Oh and probably take it in to get aligned before next race
 
I had a stock 2000 360 magnum, 9-1 comp, stock heads, M-1 intake, 501/513 hydraulic roller with 950 holley. 727 ,9 1/2 convertor 5.14 gears shifted at 5600 rpm and ran a best of 7.27 @ 94 mph in the 1/8 at 2950 lbs. Was running block huggers ,1.5 inch primary with 2.5 inch collectors through flowmaster mufflers. That should be around 11.52 @115 mph according to the Wallace calculators.
 
ok i hope this is what you was looking for.

1965 Plymouth belevdere II weighed 3750 with me in it.
1973 stock bore and stroke 440
1968 440 six pack pistons
1973 stock rods
1973 cast crank
comp cams 305 525 hydraulic cam
crane 1.6 rockers
home ported 906 heads. stock size valves
Mopar M1 tunnel-ram
2 edlebrock 750 CFM carbs
TTI header 2x3-1/2 headers
727 auto trans
No name 3200 stall converter
8-3/4 with 4.30 gears
wore out M/T 30x9x15 slicks

my best pass was a 11.60 in the 1/4 but most of the time the 65 would run 11.70 in the 1/4. i sure it could of been faster in the 1/4 with better parts, but i used parts i had laying around.

Once built a 360 that was 040" over but used std bore 340 pistons out of a 72 340 with 8.5 :1 compression. Came out around 12.8:1 with the 360 using x casting 340 heads. Ran 11.80 in 3000lb dart with 4speed and 4.56 gear. Running race gas on the street got REAL EXPENSIVE with the hi compression. Sold it to a buddy for his stock car

Basically a 360/380 create engine copy. Good job, well done IMO.
Nice and light car to!
 
1969 Dodge Dart Swinger Race Car Motor is painfully stock. Some tricks but mainly just spot on machine work.

340 bored .030 over
Stock replacement forged pistons measured at true 10 to 1
Stock x heads with small amount of port matching.
.509 lift purple cam degreed and installed straight up.
Stock stamped steel rockers
Stock intake manifold.
1 7/8 open headers
750 dp holley
29×13 slicks
4.30 to 1 rear gear
4000 stall converter.
Motor last rebuilt in 1982 or 84
Best ET for the car was 11.80s years ago.
My best ET back in 1995 was 12.0.
Ran the car after being in storage for 10 years a month ago with a few tuning issues 12.60 at 108...
I recently updated the manifold to a Performer RPM.
New Slicks
New fuel system. Can't wait to take it back out.
