Best way to run 10.90's?????

[440forPOWER]

Hello, I plan on building a new motor for my drag car (70 bee) next summer and really want to run in the 10.90,s and was just looking for some input on the best way to go about it. I am considering a 440 with a 590 mp or 640 ultradyne cam with a set of the smaller port aluminum heads (edelbrock, stage 6) but I really want to be able to keep the rpms to a safe limit to keep it alive for a couple seasons at least. Would I be better off with a 474 or 496 combo? Are they worth the extra money verses a 440? Any suggestions or input from your combos would be greatly appriciated. Currently I run the typical 440 509, 906, dynamic converter, 430 gear combo with a best of 12.14 so far.(11.90 in reach with some tuning and weight reduction)I figure I need about another 100 horsepower over my current combo which I estimate being 450 to 475. Sorry about having such a long post but its winter and I cant race so I am bored. lol THANKS

Hey 440, it's me again. As far as the mopar cams, the guy building my motor said anything bigger than the .557 always seem to go flat. If you've got the money, I'd go with a 496. Almost 50 cubes is a lot to work with. But then at the point, I would think you would want to look for something other than Edelbrock or Stage 6 heads.

I know what you mean about winter time boredum!
I think a good set of ported and polished edelbrocks from Hensley racing would do the trick, they'll set them up according to your cam and pistons. If not those, you may want to look into a set of Indy SR's and maybe an Indy intake. A big solid cam won't go flat if you've got the heads to match it and a good tork converter,etc. Consider a speed demon or race demon carb also, thet are awesome.
I'll let the big block guys finish this for you!

pretty obvious but why not just put 150 shot of NOS to it and that should get you there. That would be the easy and quick way. IS this a street/strip or just strip car?

[440forPOWER]

This is just a strip car, and I am not a big fan of nitrous. I am just looking for opinions on other engine combos that run 10.90s. I also built the current motor for the street and used stock rods and heavy trw pistons and would like to build a modern engine to run just on the stip. I am leaning towards the 474 just for the low deck (lighter weight, more hood clearence) block.

I think most of the 440/509/ported 906 combinations make around 500 HP?
If you do no weight reduction on the car, you should shoot for at least a 150 HP improvement in power, or about 650 HP engine.
I think any of the smaller port heads like the Edelbrock, Indy S/R or Brodix B-1 B/S will need some mild porting to get that much power with a flat tappet cam. A roller cam may do the trick with unported heads?
I think you will want a solid or roller cam with about 260 duration @ 0.050" lift and around 0.650" lift at the valve. On a 440, I think that your shift points should be near 7,000 RPM. With a larger engine the shift points will be lower.

Since this is a strip only engine you may want to use the Indy 440-1 (max wedge sized head.)

We run a 440 stock bore + stroke with ported + polished 906 heads with 50 thou off them + flat top pistons(12.5:1COMPRESSION)we ran a 288 533 lift lunati cam but are switching to a 308 620 lift at an engine builders request he runs 10.15 with the same motor with an 850 holley + the 308 620 lift cam he said dodge heads stall at 560 lift + with a 620 lift cam after valve adj + general wear + tear on a motor 620 becomes about 590 lift which leaves room for wear.an 850 holley is also required.on our other set up we ran 11.66 at 113 mph at the strip.we hope for 10.80's now in our 2900 lb dart.

440 for power, It can easily be done with a 440. Mine didn't go flat at all! You are actually pretty close on your ideas to what my combination is. Street legal 70 Sport Satellite,3400 lbs,727,8 in. Dynamic 5000,440 30 over,12.5 comp.,640 Ultradyne, Indy SR's ,Holly HP 1000,430's-8-3/4. Built the motor last winter in hopes of running 10:90's. After sorting out what car liked it ran a best of 10:67/125.

I run a '69 Charger with a .060 over 440 w/cast pistons, stock rods, steel crank, MP .509 hyd/cam, Edelbrock RPM heads (out of the box), Crane 1.6 ductile rockers, M1 intake and a 950hp Holley carb. 4000 stall w/trans brake, Dana 60 w/4.56 gears, 31.5" tire. All steel except hood and lexan windows, weight is 3250 lbs. w/driver. I shift at 6000 hit the traps at 6400. It runs 10.90's at 122+mph. Simple, low maintainance, not spendy and way fun!

If you want to do it right the first time Look into Koffel B-1 Heads with a 690 lift cam and 1150 Holly out of the box your life will change. Let me know what you think.

The BEST way to run 10.90's with a 440 is with a 2800 lb ladder bar car..then your current engine would do the trick!
But since you are running a '70 Bee...2800 lbs just isn't gonna happen!!
Christopher's engine is pretty close to what you have now, except for the.613 Ultradyne solid in place of your .509 MP juice cam, which shows how potent that cam is!! His 440 would probably run 11.20-11.40 in your car.
I don't think the stroker combo's are worth the extra bucks in this performance range, a 440 will get you there. The 640 Ultradyne is a great choice. I'm happy with my Edelbrocks, they should get you there...a ported set of Indy SR's would definitely get you there!

I see several of the replies mention the UltraDyne .640 solid cam.
What are you guys running the lash at on this cam.
I just picked up one and didn't get a lash spec for it. (I'ts in a complete engine). I would like to go through and make sure everything is set right prior to firing it up.
Any help would be appreciated.

65 Coronet,lash for the Ultradyne 640 is supposed to be 16 intake and exhaust.

[65 Coronet]

Mike,
Thanks for the quick reply.
Sorry that I forgot to mention this is an iron block with MP Stage VI Aluminum heads.
Is the lash the same with the Aluminum heads?
Dan

[MGM 440]

Dan, it's supposed to be 16 with aluminum or iron heads.
