14.93@86mph!
well, what is a better way to tune my truck? took it to the strip, first pass was 15.9, jet 1 size bigger in secondaries, another pass, 15.6. some timing to 36 and more fuel, 15.2. remove 14" air cleaner, learn how to drive, and wallah! 14.93@86!!!
74 D300, 318, stock compression, stock manifolds, performer intake, 600 eddie, 260/260 comp cam installed at 106 (like they said) dual exaust with cheap turbo's. no porting, small port heads (973's) stock ignition. 4:10's beat the 350ci camaro ha ha ha ha!

Go back to the track and run a series of trail and eror runs. The key is one change at a time.
Tune the primarys first. Then the secondarys. Run the advance till it pings then back off a few degrees.

thats what i did with the timing. after the second pass i developed a donut leak so i was extra carefull. i tuned the primaries already, stuck the vac advance on the manifld vac port and ran the timing and fuel up till it didnt ping. the secondaries were WAY too lean, cause when i di dmy first pass, as soon as you would open them up, it would sound like a metal shredder. the funny part is this is my work truck, i just wanted to see what you could do with a small port 318 with add ons. well??? pretty good eh? oh, yeah, the tires are 16.5, so it was screaming at about 4900 in third at the end (no tach so give or take) shifting seemed to work best at about 5200. the nice thing about the dually was no tire spin, we will see how it pulls the bobcat today, i got to take it to momma's for mothers day and spread some topsoil  rumble, i probably wont go back, i was just curiouse, and my dad said 17 seconds. man was he suprised! and there was a guy wanting to turn 14 seconds with a mild 360 and was worried about it! ha! this motor is so darn mild you have to stick your head to the pipes to hear the duration, and it is barely noticable (slight gallop)does anyone know how heavy thid truck is? i do think it is lighter than my 69 D200.

but the truck is nice! the camaro was a 74 or so (the real ugly one) and had a single plane manifold, headers, and a lumpity idle (and no compression) the typical stereotype cam and manifold special. he was so bright he even looked at my lil 318 and said it was a big block the lil 318 only wanted to launch at 1/4 throttle or so (not enough initial advance), so he smoked me till about the 660" line (sigh) chevy guys.

I figure a one ton dually with a SB must weigh close to 7000 pounds.
If we say that's true, that 318 makes somewhere around around 364 wheel hp A 12.99 second big block B body(3900 pounds) makes somewhere around 352 at the wheels So you have as much power as a pretty beefy big block car(stock ones couldn't touch 12's from the factory) with a stock compression 318 with iron manifolds, and a 600 eddy. You've either done really well, or your being really creative.

you must have run out of rpm... that 14.93 should have been closer to 93 or so. i dunno... mine is only turning about 3400 rpm at the stripe in 3rd.
been working so much that i may be able to do something with the trans this year after all, if the work holds out. except when will i find the time... lol. good job, though... i am impressed now if i had a good trans and could just figure out a way to get my 60' times down to under 2 seconds, without sacrificing the usefullness of the truck...

Tk, why is your 200 so heavy, I think my 71 200 is under 4000, and I can beat 5.0 mustangs all day with it too, so I wonder what it will run. I will never know as the tech at the track would probably not even let the truck into the parking lot, HA HA.

but, what is killing you is wheelspin, i had none. it will powerbrake, but wont spin off idle. it did untill i changed the cam it is amazing what 10 degrees duration will do to a 318!actually, from my experience, your time vs speeed is pretty high (too fast for et) i can measure teh tires, but they look like about 28" tall. (anyone know the rpm for it at 86mph?? im guessing 4800) so, somebody please figure HP on creatives ET vs speed? and mine?? i will dig it up and post his next............................

15.40@ 92?? is that right creative?? i think it is, cage, my 69 has 3 tanks, a big ol stack of springs, steel light bar, 16.5" 33's on the back, class 5 hitch and full of gas it is around 5400 (certified scales at our local pit) im thinking the 300 is about 4000 (sound right?) with me, and 5 gallons of gas, figure 220 more. im betting your D200 is like the one on my avatar (71 also) it was around 4600 i think (been a while since i cared) but, i could be wrong. anyone actually know how much a D200 (661/2-71) weighs? or a 72-79 small block standard cab D300?

31" tires (275R70/16) on 16" rims, 3.54:1 dana 60. best time and speed ever was 14.9913 @ 91.74... but the truck always seems to run pretty close to 90. lots of high 88's and 89's with a few 90's and a very few 91's. unless i really mess up somewhere, the first run i make on a given day tells what speeds will be that day... in the 88's, 89's, or 90's usually. it will run the same speeds even if the times are way off. even my crappy 16+ second runs were around 87-88 mph.
ok... sunday is race day, so i will go test'n'tune. with the hours i work, the friday night "fun drags" are out of the question. so my testing and tuning is usually done during races. i have been launching at about 1200-1400 rpm, but i will try a few shots leaving at a dead idle and see what happens. it may help weight transfer, since the braking does seem to raise the back end some. fwiw, last outing i survived to the 1/4 finals, beating 2 points leaders... one by the whopping margin of .002 seconds! went out in the 1/4 finals with a red light in a double-breakout race. could (would!) have won even if not for the light for 2 reasons... my breakout was less than his, and i still beat him by .2334 seconds. what really sucked was that i had beaten the tough guys! the 3 left all have a habit of sleeping at the tree, and usually miss their dials by 3-4 tenths. i figure i have gotten some attention, though... there is always someone looking me up. and the bottle fed mustangs seem to try to race something else.... lol. you know, .002 seconds isnt very much time... i thought he had won , then i saw my win light come on, i thought he broke out. he didnt... it was a fair-and-square win! i am telling you that that 5.0 mustang was gaining hard at the 1000' mark! all i could do was hold on and hope. i think that was the closest race that day. here is the race as it appeared on my win slip: mine-------------------------his 15.25--------dial in---------14.89 .1509-------reaction---------.1187 2.3309--------60 ft----------2.2043 6.4427-------330 ft----------6.2982 9.8301-------1/8 et---------9.6234 72.79--------1/8 mph-------73.99 12.7874-----1000 ft et------12.5225 82.18-------1000 ft mph-----84.62 15.3215------1/4 et---------14.997 88.41--------1/4 mph--------88.37 .0020------finish margin .0715--------off dial---------.1057 he should have won... but oh well... any win is a good win. the next round i went 15.18 on my 15.25 dial... and the other car (another mustang!) broke out worse than i did. my RT was a lot better, though--- .0406 slowest speed in 5 rounds was 88.41, fastest was 89.57. et's were from 15.64 to 15.16, with the truck getting faster with each round. i gotta say that the 15.64 et was when i was testing... i ran the engine up to about 1600 rpm to launch... blew the tires off when the light went green. also had the worst 60' that round at 2.57 sec. best 60' time was 2.27, which is way better than before the locker. around 2.45 then was a good 60'. i figure that i am getting a lot of slippage in the trans... it is 27 years old, and i dont know if it was ever rebuilt. if it is anything like the 318 tranny i have apart, it is in pretty sad shape. the steels in it had even been distorted! oops... didnt mean to steal this thread... ill shut up now.

Nope, not a slant six vs. a Trash Can. Please don't misunderstand my post here. I love the Mopars.
1971 Plymouth Barracuda convertible vs 2002 Pontiac Grand Prix GTP (4-door). What was your Road Runner's ET in the 1/4? My point is, horsepower is horsepower, regardless of who made the car. In 2002, the only thing that came from Mopar factories that was faster (in stock trim) than my GTP was the Viper......and a Viper can't haul 3 kids in the back seat. Of course the Viper driver would be done and having a beer by the time I got to the end if we raced. Sorry for hijacking your thread dodgeboy78.

Let's see, GTP should have the 3800 engine, thats the old Buick V6, isnt it? I guess that takes care of the Pontiac engine worries,lol! I never raced that particular Roadrunner on a strip, but I'll just say that et's are never really are a problem for any 440 powered B body Mopar if the car is set up right.

The Barracuda is "hands-down" a cooler car. If I had both cars parked next to each other at a car show, you'd barely notice the GTP. But at the drag strip, you'd have no choice but to notice it.....it's a full second faster in the quarter.

A Full Second Eh?
And what would that e.t. be on the GTP? a High 14 I'm guessing.

My personal best last summer was 14.2 on street tires. Since then I've added the aftermarket computer, which is usually good for a .4 reduction in the quarter.
Sorry guys, my fault for thinking you might be interested in anything half-way fast. I'll shut up now.

I think that Truck is kicking ass. However those in the know see that pontiac, know that it has a 3.8 supercharged, and then see the e.t. and are disappointed since the turbo 3.8's run so much better. What they don't know is how much less boost you're running. So, it's all good, go and jack that boost up and buy some racing fuel, then when your running 11's you'll be getting attention and doing Pontiac proud, until then...Buick owns you!!LOL
