He is figuring to zing it 8500-8800 or so, he is hoping it has ENOUGH gear

BTW that 735 ponies was with a 390 carb on it ..it has a carb shop 950 on it now

that dyno was done at Arringtons shop....

Scott took one of the heads off and had a guy pretty famous around these parts(Jerry Arnold)flow it, and it stopped just a smidgen short of 400cfm

Sounds like you have an old Busch/Truck motor (those 390's really flow over 600), with a restrictor plate cam, did you already dyno to 8800 rpm with that 248/258 cam?

That is what he has

Not sure on the dyno info i know that is what Arrington told him, but not sure about where it made what power at.

Will be interesting to see how it runs and how the convertor he has will work.

Hope the valvetrain's safe at the rpm you want to turn, take er easy at first, have fun, and good luck!

should be, its all Ti stuff with Jesel keyway lifters

It's the other side (springs) I'd be concerned with, those old plate motors didn't turn that kind of rpm.

I only got 1 pass had some header troubles the car did go 1.34 60 ft it was over geared will pull some gear out this wk .So here is the brake down 1.34 60ft 111mhp at the 1/8 mile and 9.71 @134.96 so not so bad for the only pass the car has made Im still running the mech water pump have not a clue on the jetting or timing yet the motor is just the way it was when I got

Re: R5P7 DART TO TEST FRIDAY - 07/04/09 03:49 PM

he actually went 135.60 mph

the car laid down the last couple of hundred feet and trapped at 8700

from the look of things, it appears that a trap of 8000 will be in the cars wheelhouse.
he is going to take the 5.13 gear out and put some 4.56 gears in before next week, should get it real close.
he left at only 3400 from the line, and short shifted it into second gear, not sure he was going to run it out on the first and only pass.

my opinion is that with the correct gear, good air, and leaving at 4500 ish(and considering he hasnt even looked at jetting or put a timing light on it)the car should dip into the 9.40's rather easily with an electric water pump on it.

not to bad with that little 248@50 "puppy" cam in it..........mighty impressive, and as they run those things on 100 octane fuel, and he was running 110 in it, i have no doubt it will like a little more timing than the 30-32 degrees we suspect it had in it last night....he was happy, and considering the frontend is a custom one off piece, to go straight down the track and have the car hook on a 28 inch tire was impressive.....

Great to hear. Nice numbers, especially 60` time! As we dont still have no special race track ( covered with this "glue" ) here where I live, we are useing old airfields for racing, then I want to ask that on what kind of race track you were? Was it "covered with glue" Hopefully you understand what I mean...
You may take a look of our race track conditions here : http://dragracing.ee/pictures/v/Speedest+Nightrace+2009/?g2_page=1
Just seems to me that 60` time is impressive with 10,5" slick.
How much you think helps water pump swap from mechanical to electric?
Did someone made vid clip maybe?

Re: R5P7 DART TO TEST FRIDAY - 07/04/09 04:09 PM

track was good...Tom Block took his blown Avenger down it and went 6.89 at 199.80,just shaking it out.

the pump swap should be good for real close to a 1/10th..that is what i saw, and several others i know who have made that swap as well.

really, considering what his liabilities were last night, the car should go 9.40's without working up a big sweat. it really was done about 1100 feet, and i think the car will go 1.29-1.30 60 foot when he gets a chance to play with it.lot left on the table with this little monster

notable head wind last night and probably about 3000 foot of air...

Forget the gear change, sounds like it needs valve springs and a cam swap!

Seriously though 400cfm on a 358" motor should want a bunch more then 8,000RPM!

Re: R5P7 DART TO TEST FRIDAY - 07/06/09 12:14 PM

Don is not doing to good on the smoking part. My boss and I made a complete new front end he used to race a lot of late model stuff and they used to build there own front ends so that help out a ton

Re: R5P7 DART TO TEST FRIDAY - 07/06/09 05:15 PM

Congrats Scott!!!

That thing is running awesome without any tuning. I got good news on my end as well. Kent is shipping my crank out today. So my engine will finally be able to be put together.... I can't wait to make 9 sec passes

I have 28" tires on my car with a 4:56 gear.. I should be prettty good on gearing by they way it sounds with your car.

Re: R5P7 DART TO TEST FRIDAY - 07/06/09 06:15 PM

I am standing also in front of question about rear end.
First - go with shortened rear end (with 14.5" wide tires)
Second - stay with normal width rear end (with 10.5" wide tires)
I hav`nt had change to weight my Charger because plastic front end is not ready, rollgage should be ready by week or so, my R5/P7 motor is still in USA, lot of small parts is still missing so I have no idea of coming race weight and that makes rear gear choice hard for me. I first thought that 5.`` is the way to go but seems that 4,56 might be enough??
Converter stall coming around 5300-5500 RPM-s

Re: R5P7 DART TO TEST FRIDAY - 08/31/09 01:38 PM

The car has been 950 @141 so far just got the convetor back had it moved to 6500 from 5300 should help the 60ft times been a best of 1.35 60ft .Still have not messed with the carb or the chassis yet

Re: R5P7 DART TO TEST FRIDAY - 08/31/09 01:58 PM

Did you get a copy of the Dyno test? Heck my W8 383 small block stalls over 7K on a 7" converter. I feel the 5300 is too low especially at 358"

Found this website the other night when I was looking to see if anyone else had a R5 in a drag car. I bought a roller cam version from Arrington's and put it in my Dart with a powerglide, 7000 converter, and 538 rear gear. The car has gone a best of 9.70 @ 139 mph. I've been tinkering with suspension and gears. You guys are right.. these motors like to rev. Change this weekend will be a Pro Systems 1000HP, replacing a 950 Holley. The link at the beginning is to some video a guy took earlier in the year....he still thinks it's a 340.

Re: R5P7 DART TO TEST FRIDAY - 09/01/09 01:56 AM

Scott's engine had a baby camshaft in it, around 248 @ 0.050" if I recall. The torque peak may not be as high as some of the other engines. The dyno sheet I saw on one of these engines had a torque peak at around 6800-7000 with a camshaft that was smaller than usual.
AL.....

Re: R5P7 DART TO TEST FRIDAY - 09/01/09 12:05 PM

Yes it does have a small cam 249 259 when taking to the engine shop that is what they run in the restictor plate motors not a hole lot of cam .My motor made 735 hp and 515tq with the plate it made 430 406 so you cane seen how much they differance there is I think the car has a 20 in it soon

what gear ratio and rpm are you working in on a pass?my cam is 275@50 and 792 lift 109cl.pulls hard in good air if it will cross at 8900 or 9000.my out out of the box 950 was real hard to get right because the motor seamed always want to pull gas from the acc pump shooters.Have you noticed any thing like this?youre car is a rocket,just fishing to see what i am missing

He has a 28 inch tire, he originally thought it would like a 5.13 gear, but didnt,.Went to a 4.56 gear, and car now stripes at close to 8 grand, shifts it about 7800 waas way out of power band with the 5.13's the convertor being redone should pick the car up a good bit, he will have it out to see mighty soon.

Re: R5P7 DART TO TEST FRIDAY - 09/01/09 04:47 PM
