Default Looking for feedback on my set-up

okay I have posted a few times on here but for the most part I am new so i will start from the begining.

I have a 1970 Road Runner and it is primarily used for drag with the exception of the odd all Mopar car show that I take it to.

I will put up a list of some of the mods that I have put it through:
8 point roll cage(but still full interior including backseats and carpet) 4200 lbs with driver(ME)
The Motor is:
1968 HP 440 Block .030 over
Steel crank
6 Pack rods- shot peanned
Block has been decked .030
heads ported and polished and shaved .030
TRW 11.5:1 Forged Pistons
Mopar cam- 610 Lift 306 duration and 108 degree lobe seperation
Weiand Team G single plane intake shaved to match
Holley 1050 CFM Dominator carb.
Chrysler billet Distributor---- weight Kit= 34 degrees @ 4000RPM, Base timing 18 degrees
MSD AL6 and Blaster 2


SMR Tranny and Torque converter
Race prep, bolt in sparg, Reverse valve body, H.D planetary

eight and three quarter rear end, 4.56 gear with spool

Ladder bar rear suspension with 180 lb coilovers

what I like to call the upside down switch ( switch on outside of trunk to kill main power)
Fully tubbed with weld drag light front and rear wheels.
rear tires are either Mickey Thompson ET Streets for when I am going to the track or going Ford, Chevy or hopped up sport compact hunting... HEHEHE

That is all that i can think of for the moment but I would really like some feed back from real Mopar guys, any feedback will be great as I am planning on adding some more power while the motor is out being freshened up. Right now it has been chassis dyno'd at 682 whp and 713 lb feet of torque, I am thinking of upping the horse to somewhere around 750 whp and looking for mid to high 9's, as the car will do consistent 10.3 right now.

Any help would be great.

Thanks

Chris

There is no replacment for displacement!!!

MOPAR or NOPAR!!!!

P.S. sorry for the rant!!!

Well I dont know how I can help I just cant for the life of me see how you get that much HP outta that combination. When I was reading it I was seeing a few things I would change.... but if your running 10.3s in the qtr I think I would sell your secrets for a million or two.

Confused Ditto

The only thing that I didn't see was the type of head you are running. Maybe stepping up to a better flowing head might pick up some pony, but like Kevin said, it looks like you are getting the most out of your combination.

I think you can gain some HP with an intake switch regardless of other changes. Herb McCandless once said that an untouched M1 was worth 30 more HP than his best dyno flogged and modified Team G. He was however in the business to sell parts, so take it for what it is worth. Depending on the head flow, my guess is it is around 325 cfm on the intake, you might be able to use a little more carb.

Otherwise from the list of parts given and the performance achieved, I am at a loss for improvements.

Six pak rods are know to be heavy.
Lighter pistons.
Better cam. Look at a Hughes, Engle etc...
Never heard good about the team G intake. Then again, never had one.
Like said before, what heads and valves/valve sizes?
Diet for the car.
All in all, it sounds rockin.

Like the above said, you're running good. The only thing I'd really change, if I were running that well, would be the rods and the pistons. Going from the near stock weight TRW's to 690 gram pistons, netted us almost 2 tenths, long ago. Same CR, etc, Now, JE, and CP can handily beat that 690 weight. But if you're replacing all that you may consider a lo-deck block. You can get into the mid five hundreds with a 440 length rod and a shelf JE F.T. Either way light weight will show up at the track, and your crank will adore you for it.

Ok... now I have read and reread this. Are you running this at one of those 1000 ft tracks up there?

I cannot see how a car that weighs this much with not much more than a hopped up street motor can run these times in the qtr. You didnt list the heads but I still doubt it, very much so.

Like said those TRW pistons are barely better than stock. That heavy of a rod cant help and those two combinations are really tough on the bottom ends. The intake is pretty bad for that heavy of a car and combination of small cam with big carb....

You didnt list convertor stall or efficiency.... what MPH are you running?

dont mean to sound so negative or provide so much doubt but with the info you gave just doesnt add up, in my opinion.

Just point of reference, I had almost the indentical motor in a much lighter Dart, I had same pistons exactly, stock polished rods (lighter) ported and polished stock heads with larger valves. Manual valve body, foot braking and was no where near your times! That car weighed 3050 with me in it. Granted I was only 18 at the time so I had alot to learn but not that much more to learn.

You're asking US for advice? Normally an engine like that would be lucky to make 550 HP. I ran your number (10.35 = 127 mph, 4200 lbs.) yields about 675 HP. You say it was chassis dynoed @ 682. did you forget to mention the 125 HP nitrous kit? Normally, you'd pick up quite a bit with a roller cam and better heads but with your numbers - who knows?

Chris, looking over your info, thats hard to believe that car runs that good with that weight. I ran the same basic combo in my challenger several years ago before going to my 572 wedge. my race weight was 3000 and could only muster 10.20's some of the difference's are I was using lightweight Venolia pistons (12.0 comp) , a M1 and 1050, and a Lunati .609- 324 duration roller cam, a O69J Turbo Action convertor. and 906 heads that I ported and polished.
I would like to know what heads and convertor you are using and what shift points are and what your 60ft times and 1/8 @ 1/4 mile mph's are.

Be sure to mag the crank while its out for cracks, ( my stock steel crank was cracked at a oil hole at the end of 2000 season) go to lighter rods and pistons, Edlebrock alumn heads are a good choice also for the price , and if you have good heads you might consider getting a 500 ci rotating assy.
Just some thoughts .......but by your stats listed, I'd be patenting that combo.... good luck.

I think you have us all guessing. My calculations are below. What are we missing from your combination?


Car weight: 4200 lbs.
Horsepower: 682 hp
Results:
Quarter Mile Acceleration: 11.578 seconds.
Terminal speed: 127.6850 mph.

----or reverse the calculation with the E.T.---

968.57 horsepower is required to achieve a 10.3 second 1/4 mile acceleration time in a 4200 pound rear wheel drive car

Damn! You want to sell that motor? I assume the TRW,s are domed? Block has been decked--Heads shaved.Definitly not down on compression.Maybe thats the secret.

What happened to this guy? I'm curious about the missing information on his set up. I'd like to see some pics too.

Maybe you all called his BS and he ran away. LOL
As for the team G intake I used one on my 451 and it did not make power ( hi or low ) untill I spent Hrs porting it to correct core shift, then it made power over 4K RPM.

Default set up

It would take 12 grand to build a motor to propell a 4200 lb sled to 10.30's.

Tour combo is fairly typical of a 12.20 to 11.70 et range. That would put you in the 10 second range at the 1000 ft mark.

good luck

Easy now boys,
I've been running 2.08 and 1.74 Milidon street valved 906 that I port myself(not enough, though) on a Wiseco'd stock bottom end and a Comp .650 and I consistently went 10.70's @ 3600# in the summer heat. Poor thing run out of air at 5500 rpm but, I figure it was as inexpensive as I could go SST racing. I will have to say that my chassis is real well sort out and it's the main reason the car even went 10's.

Mike

It's about time that you started to post again slacker! I picked up a little turbo car for the chick over the holidays. I'd post a pic but that would hi-jack this thread.

I'm still callin B.S. on the 4200 lb car in the 10's with the HP #'s listed. Just a matter of math. Of course if he's running a 200 shot of giggle juice that he some how forgot to mention.... it might be a different story.

Later,


Greg

I am going to run HTR again this year. I don't think I have a match on the 9th at Speedworld, but I will be there if the weather permits.

Just read this thread, and Im not even close to the motor/combo knowlege as you guys, and my jaw dropped when I read that time. Maybe he is running his passes at an 1/8 mile track?
