I am not Jerry, but 6.1 block I bought came fully machined from dodge dealer.

---

Thanks Rick. Is the 6.1 a direct replacement for a 5.7 with different pistons, or what else changes? I have an early 5.7 now, but have a good stroker crank and rods.

---

Same stroke 3.58.
6.1 is forged.
Bores are different 3.92 for the 5.7 and 4.55 iirc for the 6.1. The 6.1 has floating piston pin.

---

The factory 5.7 has a 3.917 bore and the 6.1 has a 4.055".

I might add that with the early blocks, the quality was exceptional..you really didn't have to do anything to them if you could live with a .002" difference in deck height and maybe touch up the cylinders with a plateau finish hone depending on ring choice. With the later blocks I would highly recommend to align hone the main bearing housing.

Yup I messed that up

I saw Jerrys truck go down the track...I thought what the heck is in that thing!! Pretty nice guy to talk with,too!

---

Thanks Ted and your a pretty nice guy to talk with too.

Yeah, my truck sure draws alot of attention. Its been nicknamed "the yellow brick", "shortbus", "fat girl", etc... Afterall when have you seen a 5200 lb 2005 4x4 Dodge Ram in full street trim (using drag radials of course) be able to tickle the 10's through mufflers. I've had as many as 20 people/racers come over to the pit after I made a rip to see what was under the hood. I always get a chuckle from the old timer's after they see my 392 HEMI decal on my front bumper and poke their nose in there and come back with, "That ain't a real 392". lol I'd also like to have a dollar for everytime someone told me I should put my engine in a 3200 lb car.

Hopefully we'll meet at the track soon again Ted, this time with one of our 5.7 G3 Hemi's being stuffed into a 69 Rambler.

This is going to be a budget build that anyone can do. We're using a salvaged engine from a 04 Durango. The Durango was totalled from a fire and bought for $900. After selling the usable parts, we're already money ahead. The shortblock is stock besides opening up the ring gaps, new bearings, Comp Cam 273, worked over 5.7 heads, INDY Mod Man carb intake, MSD, TF904 with a 8 3/4"...and a little bit of n2o.

I would like to see the Mod Man intake against the drak pak intake on a flow bench. I THINK the Mod Man will hurt the flow rate because of the short turn runners.

I dont think theres too much doubt the DP would make more torque through the range and probably a better AF spread between cylinders.

The Mod Man intake is basically a low flat intake like my buddies blower intakes.

Tom, It's all coming back to me now. Terrible thing about me growing old is loosing my long term memory. My hearing is also on the downside as to where I seldom answer the phone anymore cause I can't understand what the other person is saying. Guess its time for hearing aid's lol

Indy claim some benefits from the super large plenum on the modman...meaning none of the runners go "lean" due to distance from the source....but the short runners ARE a worry.

I guess Ill find out soon enough....

---

The only real way to find out about even fuel distrubution through an intake manifold is by recording egt's per cylinder at the dyno. The factory intake manifolds I tested had all 8 cyl egt temps within 5*'s at 6000 rpm. Giddy up. A carburated DP intake needs some help with air flow. Maybe we have to break out the popsicle sticks and epoxey or someone may come up with the correct jetting. With a DP EFI intake you can dial in every cylinder for timing and fuel.
