I know this has been asked a lot of times in the past. I love looking at different engine/car combos. I'm putting together a very a mild combo. I would like some guesses on how much power/torque and what it should run. For motor it's going to be a .030 440 with the 3.75" forged crank. I have some small dome bme pistons. They weigh 721-722g with out pin. They're the 1.094" stock pin size. With pin they're 865g I have lite weight pins. I will have to check and see if I can come up with a cc or mock the block up and check and see what kind of cr I'll have. I'm thinking like 12:1. Haven't decided on connecting rods yet. I have ootb 440 source heads 80 cc closed chamber. I have steel retainers, 1107 spring's, stainless valves. 1.6 440 source rockers. I have a team G 4500 tall top with some plenum work done to it. I have a 9375 1050 Holley that might be converted to E85. Planning on like 1 7/8" primary tube headers with 3" collector. I was thinking 2" and 3.5" collector but that could be a bit much. Hopefully getting a comp cams 567/567 264/264 @ .050 106 lsa solid flat tappet cam. Plan on keeping oiling system pretty basic hopefully. Trans is a 727 and it will have a trans brake. Looking at 10" converter in the 3,000-4000 stall range. I'll probably be using a 4.56 gear. I'm expecting car to be around 2500-2600 lbs with driver. Thoughts, opinions, and sharing different combinations would be greatly appreciated. Thanks moparts. Maybe some of you will have fun with this.

I think you'll run 10s easily at that weight. I'd use a better intake and more stall.

My old 440+.030"=446" combo ran 10.40 at 129.1 mph at 3700 lbs.
Ross domes, 14:1 compression, Manley H beams, stock crank
Indy SR heads, out of the box other than being shaved down for compression
Weiand Team G manifold, 1050 dominator
Herbert solid roller 266°/278° at .050", .660"/.620" lift, 106 LSA
727, 9" 5k stall, 4.10 gear, 28x10.5 slick

I think you will be closer to 9's at that weight. I went 10.60's in my Duster at 3230# race weight with a .030 over 440 TRW slugs, stock crank and rods. OOTB Eddy RPM , MP .509 with a M1 and HS 1.5 rockers. 2" Hookers 4.56's and a Coan 5600 stall converter. All on pump gas.

I got the Weiand Team G off a friend for $75. It worked good for what it is on his combo. I'll be sticking with this intake for a while since I have it. The converter I can look to get a higher stall since that hasn't been purchased yet. Only looking to run in the 10s at the fastest. I want to avoid the 9s for now and all the rules until a later date. Thanks for the shares, and the feed back so far.

Our dragster weighs right at 1900lbs and goes goes 8.40's at elevation in Vegas, generally .3 slower than sea level FWIW. Stock block stock stroke Chinese rod ross piston 446 with a set of mildly ported -1 heads(too big really). It is actually the motor for my 68 D100. Pump gas, just under 11-1 compression very small roller. Should be plenty to propel a 2600lb car into the 9.30's at lea level.

Dads goes 11:30s and its a 10:1 440, CNC stealth heads, 600 lift, 260* @.050 with a victor intake and 850 Holley. In a 3500lb corone

For the guys running LY rods, or a cheap I beam/H beam rod. Was is your thoughts on those?. I found some I beam rods on ebay and the company claims they will handle 800 hp. Has ARP bolts. They weigh 800g, and they're $255. They're cheap H beam rods but most of them have the .990 pin.

At that weight...it takes very little to run 10s...

Ported 452s (flowed 262@.600), 10:1 comp, 440, M1, 950HP, 259/.550 Comp Solid, etc. ET/MPH in my sig at 3800 lbs....That combo would be knockn on 9s at your weight.

Rods are no place to pinch pennies. Long before I'd run a $255 I beam from an ebay vendor I'd run LY rods. Of course they CLAIM up to 800 hp. Sounds better than "Use at your own risk about 500 hp"...LOL.

Another PROVEN "budget" rod are the ones from 440source.

At that weight you should have no problems hitting 10's.
My Cuda at 3400 ran 10.82-10.90 w/.040 over 440, 6 pk rods, heavy trw domed pistons, 590 cam, weiand intake w/750 dp and 452 heads from McCandless. This was engine lasted from 1988-2002. Was very consistent.

Get the heads ported, a decent 5000 converter, 2" supersucker and you should be in the 9's
My old motor ran 10.1 at 3150.

Here's mine

'69 Cuda 3000lbs at the line,
1968 440SP block +.030", 10:1CR
Single external Oiling by Milodon
mildly ported 906's, 2.14/1.81
HS Roller Rockers
CC .650" 290@.050 solid flat tappet cam
Team G, 850DP, 2" f/wells
Race 727, 4500 verter
14x32's, 4.88 gears
Ladder Bars/coil overs
35sp Strange spool/shafts
stock fr suspension w/90/10's.
Went 10.7@125, 1.46 short time

I'd love to hear more about this combo. What gear and converter?

With my Demon the best I've had so far is in my SIG it weighs 2950 with me in it...

My Buddy duster with similar setup with trans brake went 10.05 back to back in good air both are stock stroke combos


I would suggest a better converter for your combo..... What car are you using this in

The only thing I'm going to add here is to leave the LY rods in the scrap box and buy a decent set of rods. Somewhere in my shop I still have the LY that is now a jigsaw puzzle that cost me an engine after it tossed at the 1000 ft mark one night.

Low 9.80's twenty plus years ago with a .030 over 440, stock rods (shot peened and new 3/8 bolts), TRW pistons, stock crank, roller cam, Weiand tunnel ram with two 750 holleys ( 76 jets Summer, 78 jets Fall), ported 906 heads. car weighed 2700 pounds, 727, J convertor, 14-31 slicks, and a 4.45 dana rear. Don't be afraid to go with at least a 4400 stall convertor at least. Same combo ran 10.0's with a single 1050 carb.


I will be a cake-walk with Stealth heads.

What car???

Is this going to be a race car ? I am just curious as with the 12.1 comp it dont sound like a pump gas combo so I am guessing its a race car only ? But yes at that weight it wont take alot of hp to run 10's. Good luck , Ron
