Did a little racing at MoKan yesterday with our 225k mile junkyard hemi resulting in shattering previous class ET and MPH records along with getting the win. It went 6.83 @98.3 mph in the 1/8 with a VERY basic engine combo in our 3100lb Ex cab Dakota. The lil hemi is nothing more than a stock 04 shortblock, wearing a pair of lightly touched up eagle heads, comp 273 cam, PAC springs, Ritter intake w/ 950 carb on 93 pump gas. This thing is a monster for what it is and put our previous 360 magnum power plant to shame. I must add that the 360 was pretty stout having almost 11/1 compression, ported 2.02 valve magnum R/T heads, 250@.050 SFT cam and Indy intake with the same carb. The 360 could only muster 7.18 @ 95mph. For those those that are on the fence about going gen III hemi, this should help sway some to take the leap. Sure glad we did!

This is pretty cool...I've considered a similar engine to put in a 2700 LB race weight car.

What rpm do you shift at?

Nice results. I have some Eagle heads sitting on the shelf with Pac springs . I was saving them but I might put them on my stock short block.
What thickness head gasket did you use?

Any decent guess at your compression?

What kind of timing are you running?

Totally stock valve-train?

Still pulling to 6900?

Thanks for sharing!

Stock rockers and shafts. It does have Comp hardened 5/16 pushrods. I would have used the stock ones but didn't have any from the Eagle head donor engine. Compression is in the neighborhood of 12/1. Stock head gaskets. This thing revs very quickly. It's like a 2 cycle. You have to be very careful in the burnout not to turn it over 7000. Yeah it's still pulling like a fright train at 6900. We did stick a used 6.1 oil pump in it for a pressure increase. I think it will live for quite a while under 7k. I have not messed with the timing at all yet. Timing is as delivered from MSD. Doesn't show any signs of detonating at 24* total. I'm gonna put my Sullens E-85 carb on it and see what it does. I think there is a tenth or maybe 2 on the table by just making the switch to E.

Thanks Dustin! I've been following your build as well. I'm wanting to replace the 440 in my Duster with something similar to your setup. I want something that is low maintenance and hauls the mail naturally aspirated. Your car is very impressive!

How much cam lift at the valves and what kind of clearance to piston.

This is a shelf cam?

Comp 112-502-11 cam. Known as 273 xfi cam. .550/.547 lift. Clearance is tight. Not much room for anything bigger without intake valve notches on the pistons. Tried a 229/235 Drag pack cam but would not clear factory 08 and down pistons. Intake valves were contacting pistons.

Thanks again for answering all the questions and sharing the info, very much appreciated...

I want one of these motors. I'm wondering how this would run with the Edelbrock 6.1 clone intake. However, I like the simple and very effective approach of your induction and timing system - good stuff!

I had asked earlier in the year, who had a streetable high 10/low 11 second G3 combo and you nailed it!

I'm leaning over the G3 fence after buying a pair of Eagle heads, just to see for myself. I was impressed by the flow numbers per dollar.

What trans/converter/gears/tires combo are you running?

Pretty much. Don't forget the Ritter intake. 😎 It's almost disappointing that the engine idles so smooth and is so docile. It just doesn't sound like I think it should for as well as it performs.

Bad340fish, I'd love to bring it but truck won't pass tech there now. We were warned a month ago when it was there and a half sec slower. It only has a lap belt at the moment.😳 The motor is coming out to go in a caged RC Dakota for next year.

1.48 is its best 60ft so far. 1.52 is is the worst we have seen with the hemi. For comparison, the best the previous 360 mag ever produced was a 1.54...

Been watching a few of the engine builds on here , I knew the Gen3 was good but seeing track results Wow ! , it's giving me the itch to do something with the stock 6.1 in my Valiant , or sell it of and do a budget 5.7 like this one .

got a few questions if you dont mind . Did you replace the rod bolts , What's the converter flash to , Is your gearing optomised for the 1/8 , what you think it would do in the 1/4 .

We do have a really good 8" converter from Ultimate. We footbrake it and it flashes about 5k. As far as the gearing I don't know because we ran out of time to test. Previous 360 magnum engine liked a 4.30 gear. With it, we tried 4.10 & 4.56. Both were slower in 1/8 & 1/4. The engine has all of its original fasteners and bearings. I added a 6.1 oil pump for a little insurance. Checked a couple rod bearings and they looked perfect with 225k on them so I just bolted it back together and went with it. Haven't got to run 1/4 yet. I'm guessing 10.80s or better.

Are you using the stock motor mount location and using the front accessory drive for the OEM water pump and alternator?

Thanks everyone for the positive comments. The headers are botched to say the least. They are actually cheapo pacesetter 1 3/4 headers for ram pickup with early port heads. So port alignment is not even close for the eagles. Reworked a couple tubes on each side to make them fit. A good set of headers would probably make a noticeable improvement. We don't run any accessories or alternator. Used a truck timing cover and rigged a moroso pump drive to the factory water pump. The mounts are a combination of Schumacher BB perches and street and performance engine mounts.

For the early Dak with a G3 hemi swap, might want to look at the A-body G3 Hemi headers.

I'd be surprised if A body headers will fit. The passenger side upper control arm
Is very close to the head. The frame also angles inward directly behind the engine with the rear lower control arm mount also taking up valuable space. It's just tight.

ric3xrt I appreciate your input. I looked at different headers for hours trying to find some that I thought I could make work. Even some LS and Ford headers. I was willing to cut off the flange and weld on a hemi flange but there didn't seem to be any that looked close. So after all of that, I said heck with it and bought some cheapos and went to hacking. sawzall weld

I'm just wondering what the early 5.7 heads would do with the same cam-combo. Maybe a little port work on the heads too. Sounds so enticing with the parts starting to flow with the Gen lll hemi.
