my turn what will it run - 04/01/09 05:44 PM

I'm bored and I plan on firning the engine soon, and getting some track time by the end of the month. so here goes I'd like to see 12.30's

70 Charger (no heater box or headlight buckets) Stock Interior. column shift, 318 t-bars.
Standard bore 440, TRW 6-pack pistons (.020), ported 516 heads 74cc using Fel-Pro headgasket (approx 10.75:1) w/ 2.14/1.81 (flow 260/190), 528 solid cam, 1.5 roller rockers, Aluminum 6-pack set-up. (carbs will be adjusted well before running), MP distrib, MSD wires, coil, headers, 3" all the way to the bumper, 727 w/ performance build, 2600-2800 stall, 3,91's. I will be running slicks, probably an L60-15.

You're being optimistic , I was thinking it wouldn't barely break 15 sec ???

I ran a 12.16 in my car with a very simular combo. I had the 282 DC cam and stock heads. I had 10.7-1 compression. Mind you, the weather was perfect. I would normanl run in the 12.3-4 range though.

you did not say the weight[3600#maybe]
12.50 i think your tires are a weak link.

a 28x10.5x15 slick is not enough? I'll probably use ET streets or a similar type.

how did you get .020 pistons into a std bore block?

Re: my turn what will it run - 04/01/09 06:21 PM

sorry all i saw was the L60/15.i figured you ment a pro trac street tire or something.

I didn't do the build. All I know is they are forged 6-pack pistons (with the reliefs) and they measure about .020 in the hole.

nah I ran 12.90's in a 67 coronet (3900lbs w/ me) w/ a maybe 9:1 440, stock 906 heads, Summit 488 cam, rpm intake 750DP and headers. With a similar stall and 3.91's. This car is lighter, has more compression, better heads, better cam, better exhaust, and better carbs...should be better than a tenth faster. Buddy ran 11.80's on a stock 67 GTX w/ a similar set-up...his heads were a little better and he ran a 509 w/ 4.10's. Not that I expect to get close to 11's....but jeesh I hope it's better than 12.80's

Jeff, I'm thinking your looking at high 12's low 13's there. I'll go with 13 flat.

12.50 or faster if properly tuned,i,d guess low 13,s to start with and progressing to the 12.50 range after you figure out how to make it happy. Good luck

I agree. the cam you are using isn't that great. 509 in our experience will give you more but not as nice mannered. A little more gear would help too.

Re: my turn what will it run - 04/01/09 07:47 PM

FWIW,

My old 440 was 10.5 to 1 with ported 452s. 509 Cam, m1 intake, 800 DP, 10 inch converter that flashed right at 4k, 4.30 gear, 3850 lbs. Ran a best of 12.46

Id think that charger shoud weigh really close to 4k if not a hair over.

IMO, you need way more converter.

Id say high 12's at best.

13 flat? come on...this car is lighter than my 67...and it has way more motor. was the 67 a fluke or something? I'l be really P/O'd if it doesn't run at least 12.50.

"Id think that charger shoud weigh really close to 4k if not a hair over."

I think it was an ex-race car...in a past life. It has a glass front valance, no heater box headlight buckets and the front fender boxes (behind the headlight doors) have been cut out.

My stock stroke 340 with unported X heads, a 274 hydraulic cam and a little 650 Holley runs high 12's in a 3,600 pound A-body.

A buddy had a stock compression 440 with mild ported 452's, Comp 292 cam, SD intake, 750 DP, 2800 flash, 3.23 gear in a 3700ish lb b body. Ran 13.30s-13.40's.

what did you do add 600#s to it never seen a 3600 pound duster

Re: my turn what will it run - 04/01/09 10:06 PM

Fwiw...fresh zero deck 440 with the 528, 830DP, 452's cut for compression mild clean up, RPM, 4.10s and a 3800 stall, 3750 lb car went 12.50's. I'd say your close or better than that imo...

That's with me in it and a half tank of gas, and I don't weigh 600 pounds. It was weighed on a certified scale at the scrapyard too. It has a full interior, all metal body with the big chrome bumpers since it's a 1973. A/C car, sound deadening. It's a fat pig for an A-body.

Re: my turn what will it run - 04/01/09 10:51 PM

Perfect conditions with an RPM and 850DP on it 12.0 @111, Six pack and average conditions- 13.40, maybe a 15.40 depending on how bad it bogs or spins.

There's some great running 6 packs out there but you can probably count them on both hands, I usually consider that car show stuff.

You must have some bad tuners there... I have friends that have run 11.80 and 11.75 in full street trim b-bodys w/ 440-6's and 509 cams...one swaped out the 509 for a 557 solid and dropped it to 11.70 spinning @ 119 in a 4 speed car.

the dart in question was a stock 340 "J" headed car w/ 3.55's and a 625...when I added a 750DP I got it to run 13.80. Ran out of cam around 5k.

That's about what I'm hoping/thinking. I had a torker w/ a 750HP but hey the 6bbl looked nice..

Re: my turn what will it run - 04/02/09 12:24 AM

Jeff,

I think you are close. Our combo was the similar; gear, convertor, motor had less cam (509; I know you hate them...), 10.0-1 compression, ported steel open chamber heads, 850DP, weight was 3350 w/o driver. 12.0's in hot sticky weather; 11.70's in good air. 70 Chargers are a sled (I think the front bumper weighs as much as the rear), so weight will be a big factor.

The squish heads will help prevent detonation, but I think you are on the edge without running a little race gas when you flog it.

actually I like the 509 with the right combo. They make good HP. It will have 110 in it at the track. The car should weigh around 3800 w/ me and gas. Remember it is missing some pieces

Re: my turn what will it run - 04/02/09 01:27 AM

509 is more cam that the 528 solid.

Re: my turn what will it run - 04/02/09 01:37 AM

Should go mid to high 12's, needs more converter

Re: my turn what will it run - 04/02/09 01:40 AM

Its slow but not THAATTT slow. Needs another big block. Unless someone wants to donate a set of W-2's.

I agree with this. It could run mid 12's if you hit the tune dead on and maybe run even low 12's. But if the tune is off any you may be in the low 13's. And I also agree I would use more converter. I wish you good luck and honestly believe you will have it somewhere in the mid 12's for sure with your knowledge. Ron

FWIW when I had the 440 in the challenger, same combo as we had in the Fury but with a 3k stall converter, and the challenger weighed 3855 with me in it, it ran 12.80s through the exhaust,and a best of 12.50 at 110 open headers...

Re: my turn what will it run - 04/02/09 03:52 AM

Wow. I've got more faith in ya. You're a tuner - you'll go quicker than 30s. Maybe not the first time out.

Compared to what you have, I use to have way more weight(4250 then), MP 272 .455 cam, same CR as you, 3.23, BFG P235 70 14, same head flow #s, 6 pack, iron exhaust manifolds and 2 1/4 mufflers and the car went a best of 12.85 just short of 109. You should be able to go 113 or 114, and with a good 60 ft, put you close to 12.0s

Re: my turn what will it run - 04/02/09 12:18 PM

Thanks guys (most of you ) I do have a 3-3200 on the floor if I don't like how this one works. I'm using this one because my friend had it behind his 440-6 w/ a 268 comp cam and it seemed to work well. Since the 528 has a range of about 2400-6200 I thought it'd work pretty good. I also do drive the car or will be driving the car way more than race it I wanted something that ran well on the street.
