...a 650dp, 4.10 gears & a 2800 stall, Car ran 12.5s @ 105 on every pass, 1.80 60ft. times on 275/60/15 MT DRs, It was so efficient all it liked was 30* total timing, i tried 32* & it slowed, It ran a best of 8.06 in the 1/8 at 85, I install a 125 plate system on it, On its only decent pass it...

Run the longer rod!

Your not really down on power, your converter "now" is blowing the tires & your 60fts. are horrible, you'll gain some MPH back once it hooks, Your ETs will really improve also.

Thats what i ran in my 71 swinger with a 95 junkyard 360 magnum, the bottom end stayed stock, installed RHS heads, re-ground factory cam, RPM intake, 650dp, headers, 2800 stall, 4.10 gears, car ran 106 @ 12.50s on 1.79/1.80 60fts., ran a 125 shot through it & pulled off 7.4s @ 96 in the 1/8 with...

What oldkimmer said, before you just give up on the build (BTW its not that wild IMO) get the tune right & look into rhodes lifters, I'm not a big fan of eddy carbs with larger cams, I'd invest in a good used holley 750dp 4779. When you start hopping up an engine & lowering manifold vacuum it...

I've witnessed some really fast Mopars on slapper bars, most that think they don't work don't understand them or know how to dial them in, there old technology but they worked, chevies have "nothing" to do with it.

Finally took the cutlass to the track, ran it on street tires, made 3 passes & threw 2 alt. belts, was shifting at 6800, other then not much traction i think she did pretty good. Best pass. 13.03 @ 107 on a sad 2.20 1st. pass was a 13.28 @ 104 on the same 2.20 was wanting a 12.8 but...

Agreed, I just hauled my car to the track useing a U-haul car trailer, they only need the make of the car your hauling for there records.

I'll say 13.0s with the 355s, now thats on a good run.

IMO, it all ddepends on the combo, heads/cam/gear/stall whether a 750 will pick it up, I say try one if you can borrow it, or get a PF mainbody & drop it on, I think it'll run stronger ET/MPH with a PF MB over the 650 even on a not so wild 360, so your buddy might be onto something. I ran 12.5s...

I'd start adding more timing, 32 * seems a tad low, run it up untill the MPH falls off, then start jetting it up untill the same thing, That 850 should be more then enough carb, i'll bet it runs better with a 750hp.

No there shouldn't be if its tuned in right, that cam can get close to 13 inches manifold vacuum or there abouts.

Sounds like you need to go to your local book store & pick up a holley perf. tuning book & read it, you'll be surprized what you'd learn, not trying to sound sarcastic, but from what your asking it sounds like you don't really understand how a carb works.

Are those Aluminum heads i see, he has iron, big difference.

Have a grille & bezels for a 75 duster, there in really good condition, asking 75.00 obo plus shipping. PM here. Located in SW, Missouri 65673

If your wanting mid 11s you'll need at least a 150 shot, maybe with what you have. At this point you'll need a better fuel supply, IMO, anything above a 150 shot requires a deticated fuel system for the nitrous, or a VG single set-up on a 150. If you do it right & have all your ducks in a...

People on the web will say anything to make there ride shine trust me, the chevy guys will say the 406, the buick guys will say the 455, thats nature, now, i hope you don't think i mild GS430 buick is going to run low 11s, I've been around, i'm 48 yrs. old, i was there back when these cars were...

Here was my little 451, times are in sig. 400/451 Ross FTs, 9.73 compression 440 steel crank, 440 rods, ARP bolts Stock 906 heads (stock ports) Comp 282S cam Weiand Street Ram with 2 600 1850s Running lean in the heat, sorry 60ft times. (1.63)

Shoot for 10.5.1, even 10.7 would be fine with aluminum heads & that cam.

Remember, i'm not running a 355, its a 406 & it has plenty of torque trust me.

What car :burnout:

Can't compare a 68 to a 78, there 2 different animals, I've beat up on chevys to, but now that i'm running one, i have to talk the talk.:glasses7:

You got beat by a chevy, shame on you, tell you what, i'll run you with my 78 cutty, its a 406 sbc & doesn't have nitrous :D

Even though your at sea level in Cal., the air is dryer, less chance for detination, but whatever the OP decides, its his engine, i personally would'nt be wanting 11.1 over 10.5 just for bragging rights & chance detination with diminishing returns do to lack of timing.

I would check valve stem height 1st., then see if the lifter feels soft (spongy), you can feel that by pushing down on the rocker (lifter side), if its spongy, it just needs to pump up, i've had to replace them, even on a new builds, I don't use anything but comp magnum anti pump-ups on all my...

Whats the intake closeing point on that cam?

...timing for .5 point your defeating the purpose & you won't be happy, my machinest stronger recammended i stay just below 10.5 on my 406 sbc or it WILL detinate, i trusted his word & i'm very happy, it runs on 91 with 36* timing, it also has a smaller cam, Dynamic #s are around 8.1, Static is...

You ain't chitten!!

Not on pump gas it won't

In houston your right at sea level, even with 93 octane you'll be hard pressed running it on 11.1 with iron heads, detination city, you'll need to pull way too much timing & you won't be happy with the perf., shoot for around 9.8 or there abouts with good quench, modern heart shaped combustion...
