What is the cam?The only problem I can see with not hitting the 12's is the street tires.Those and 4.10's and being 26" tall equal mega spin off the line.At 3000 lbs is the car stripped down and fiberglass equiped?

Smells like mid to high 13's. If the cam you are going to use is larger than the .484 Mopar Performance cam you will probably have to play with the springs in the secondary carbs to get them to open at the right time. If they are left stock they may launch ok but they will shut and suddenly you're racing with a 340 2bbl.

Comparing it with my best freinds 67 I'll stick with high 12's with tires.Now to shamelessly plug my buddies ride check out page 12 of the current Car Craft(oct 2000).The car is a 67 barracuda fastback with a race weight of 3590lbs.The motor is a 360+.030 that was yanked from a Pick and Pull.The motor looked clean and reasonably fresh so all it got was fresh bearings and a genaric Summit 276/286 cam.A quick trip around the bowls with a tootsie roll sander to clean up the valve bowls was all that was done to the boneyard heads.Oh yea,milled .060 to bring the compression up to 9.The motor is topped off with an old style torker and a 600 holley vac secondary.The trans is a stock 727 with a fresh home rebuild.an 8-1/4 with3.55's,suregrip and 26x8"drag radials.No snubber just some spring clamps on the front of tired stock springs.This car is running 13.5's@102 with 60's in the 1.95 to 2.0 range.Sounds like you have a much stronger project than his.

Sorry about the lack of info. Just a mild brain fart. I'm using Hughes 1.5 alum roller rockers with a Hughes Hyd cam.
.515 intake .535 exh.
276 dur 286 dur
110 lsa
part number HE 3038AL
I also fogot to mention that I will be running TTI 1 5/8 headers thru a 2.25 mandrel bent exhaust. I havent decided on the mufflers yet. I want power with a deep sound but not super loud. Suggestions???
There is no fiberglass at all. try not to laugh but I ball parked the total wt. I shouldnt do this but I'm assuming the wt. on my registration says 2850. I'm running an alum water pump and alum heads which I figured would reduce the wt by 50 lbs but that may be out of line. I weigh 200 so I came up with 3000. I'm sure you guys have a better Idea of the true weight...........
Keep on flowing those ideas. Like I said, I'd like it streetable for the weekends and If I need better rubber then so be it. Thanks. By the way...does my setup look like it matches or is something grosely out of line with it.

I think your weight estimation is far off. You'll be much closer to 3500 lbs than 3000. Over or under, that's an other question. I think the 2 1/4" exhaust may be a bit on the small side, I would go 2.5" instead and use Dynomax Super Turbo mufflers. They are realtively quiet and give good power. I think otherwise your combo is pretty good, and if you can get the six pack tuned and some traction you'll be in the 12's despite of the weight. I think your car would run better with a single 750 cfm four barrell on a RPM intake though, and it would be easier to tune right too. But if you want a six pack, that's what you'll use I guess. I highly recommend getting some good tires for the car, I think that with a real good driving it could make the 12's even with regular street tires but the fear of smoking the tires is obvious.

The combo looks good for a street/strip car, but I think low 13's, maybe high 12's?
Get the 2-1/2" dual exhaust with Dynomax super turbo mufflers. The 2-1/4" is too small.

One of my friends runs a Challenger 360 cid with the Edelbrock heads, but more cam and converter, and a 750 Demon on the Mopar M1 single plane. The car runs high 11's.

I think mid 12's, weight estimate is a little low - I expect 3300 to 3500 wet weight with driver, cam looks good and the rest seems to be matched pretty well. Sounds like fun!! Good luck!

If you don't hit some 12.50's, I'd be surprised, that's is with some 28" tires. With those 26" street tires, that motor is gonna be cryin' it's ass off before you hit the lights. Beleive it or not the driver has alot to do with the car runs.

I think you're a little low on the stall for that cam and if you want to get some slicks or DOT tires go with a 28"...for sure.

I agree with the thinking that you would need more stall in the converter to get where you want it to be. Thay way you can run taller tires for lower 60 foot times and not pull down the 4.10 as much. I also agree that a single 750 cfm on a performer or torker would be easier to tune and be more consistent, BUT the 6pak setup will offer more top end when tuned. Good luck -- I love those 67-69 fastbacks and notchbacks!

my ride. 72 cuda.60over 360. Edelbrock heads opened up at Indy. Comp cams 305dur. 525lift. rpm intake. cast pistons. and stock rockers. Set too much preload on the lifters. Wiped a lobe off the cam. Workin on it right now. 1-5/8 heddmans. 2-1/2 tti exhaust w/terminator mufflers. 3.91rear 3500 stall. 750 demon.. mech.dist. with chrome box..275-50-15(26") nitto drag radials-(got to have them.. killer bite and ride good on the road) took it to Roxborro drag way in NC and first run went 8.09 with 1.75 60ft at 86 mph. a good friend of mine at Hensley told me I could have been losing about 50-75hp with the extrapreload.That 8.09 was probably about a 12.50 in the 1/4.the car is set up for street. full interior and all the steel on the outside.Your A body should be down about 3200 lbs. This motor is the same motor that was in mopar action less the heads and intake which I aquired from Indy.Made 497 on the dyno.

Wow, thanks for all the input. You guys confirmed alot of what I have been thinking about doing also. One quick question before I go on. When I set my rockers up, I was going to use a .03 preload which is basically in the middle of the range that Hughes recommends. You guys agree with this or is it going to ping or be too heavy. Thanks for clearing up the weight thing. I musta been dreaming to come up with 3000. I also know that the 6 pack probably wont deliver as much as a 4 bbl on a single plane but ever since I got my first taste of Mopar, I owned a 69 superbee back in 75', I've always wanted one. I have been thinking about sending it to Six Packs To Go. They change everything into a mechanical pkg with accelerator pumps for the outboards and full progressive linkage. I've talked to a few guys with this change on their 340 and they all swear it was like giving it a blast with nitro. The converter that I put in there is an 11" modified Hemi. My tranny guy got it from CTI. He has had excelent results with this so I'm probably will run this for awhile and see how this combo performs before I change it. I was a little concerned that because of the extended, lower MPH crusing I do that it would barbeque the pig with a higher stall. I agree on the exhaust dia being smaller than I would like. I got this project a year ago and the guy put this system on just before I bought it so its still new and untill my wallet fills up again it looks like i'll stay at 2.25 dia. Thanks again for all your help.....DAVE

My 69 Fastback Barracuda weighed #2957 fully loaded and after I removed the stock Mopar seats,front and back and installed 2 race buckets and a 6pt roll bar,it weighed the same,so I belive Dave's car weight is close to being right.Shipping weight from Chrysler is #2850.

Dave,

About the rockers..... This is what I do on an assembled motor. Install the rockers a bit loose(not so loose that they'll fly out)and start it up and let the engine warm up a bit.

Go back and turn the motor to get the lifter at the base circle of the cam. Snug the rocker to ZERO lash and add 1/4 turn and that should do it. I've never had luck on a Mopar with a feeler gauge.

dave,your forgetting that edelbrock heads will outflow stockers right out of the box!!and now you've ported them & your going to run 2 1/4 exh?pahleese!!!!I have 1 360 w stock edelbrocks and had 2.5" exh,went to 3" & picked up 5 tenths in the 1/4!!!!!my inner fenderwell less 65 valiant weighs 3050 lbs w/o me,Im sure your around 32-3300 lbs.heres my combo for comparision purposes,65 valiant 360,10.5 actual comp,hypereutectic pistons,509 mp cam,2* adv,edelbrock heads,273 adj rockers(.010 preload)1 7/8" hooker headers,tunnel ram,800 dp holley,electronic ign,orange box,16* initial 38* total@2000rpm,4 spd(3.09 1st),3.23 posi runs 12.28 @ 107 on street tires with no traction,1.8 60 ft,on pump gas 91 0ctane.u will run 12's no doubt as long as u tune it properly maybe 11's.Personally I love 6 paks theyre great flat out but intown driveability is bothersome,the mods u mentioned are great but expensive,use an alum intake only,u did balance the engine right? I dont like the hughes cams much,that isnt to say I love mp's either but I prefer them over hughes based on actual track times not an opinion,never ran 1 in a small block though.2800 stall w/26" will give u an ok holeshot but will kill driveabilty at 75 mph,28-3200 would be better with 27.5" tires,my car will go 11's easily with a gear change(3,91s) and faster w/slicks,your potential is greater than mine on paper.By the way my son & I picked up my long block when it was hanging on the picker....its light no doubt but dont run 6 cyl torsion bars,not enough weight on the front end!!dont forget a pinion snubber & u must!! reinforce the floorpan where it contacts or youll go right thru it!!!SS springs make the tires hit too hard on the street,a little spring windup will let u come out of the hole a little faster w/o wheelspin.sounds like a great combo,Morpower to ya!!...PRO...
