Thanks to this site and all the friendly and helpfull people here; Mr Hemi gave me permission to post pic's and details of a complete build for a supercharged Hemi engine. We will take you through the step by step process. From pulling the motor, to the final tuning. Starting tomorrow morning at 9 am, we will be tearing into the truck. We will give you a day by day post and pic's of the truck in progress. Currently, there are 11 other on going project vehicles that are being worked on. Somedays my truck will have to take a back burner. I want to take the time right now, to thank the many people on this site, that have answered all my many questions and make this happen.

Does anyone know what that means in Lab talk?
Yeah, my new Golden Retriever says it means "Hurry up with the new pictures!"

ktmrider, Keep what you have. We measured both the AB and AC cams and they are identical. I read about the cam differences on the other site too. So since we had both the AB and AC cam's in the shop, Denny decided to measure them. Both measured the same.

Having problems getting the pictures out of the camera into the computer. Bare with me.

I'm still having problems with getting the pictures out of my camera. I'll try using Denny's tomorrow.

However, Here's an update on the project:
We recieved the valves yesterday and dropped them off, so we can now get the valve job completed. We'll get them bench flowed tested after that and post the numbers. It took a full two months to finally get the valves. We should be able to order the pistons next week. The studs should be here tomorrow. We just recieved the new slicks and rims today. I hope I have answered all the emails and PM's on the left over parts. If anyone is still interested in any of these, this is what we have left. One 6.1 cam, one 6.1 crank and the tires and rims. The price of the tires and rims have gone down, since I recieved a decent deal on the new ones. Hopefully I can get you guys pictures by tomorrow.

Thanks

Mr. Envy
So what do you think are the weak points,if any on the stock blocks? either one..
The 2 bolt caps? - oiling?
How were the original line bores on the 5.7?
Whats the difference on the 6.1 head? the exhaust runner size and port? the bowl size?
Inquiring minds want to know.
Thanks - keep it coming.

Solar_Ram, I really haven't seen any weaknesses in either of these blocks. After sonic checking these blocks, I know you really don't what to bore them out very much, or at all. I might go .020" max. The 5.7 block has seen more than 500 RWHP, NO2 and F/I, put to it with no failures that I know of. The reluctor wheel is the weak link in the 5.7's rotating assembly. The 6.1 has 4 bolts holding it on to the crank vs the 3 bolts on the 5.7 and the 6.1 reluctor wheel is .050" thicker than the 5.7. The oiling system is next to none on these blocks. Jay, hit the nail on the head, for the 4 bolt cross mains. I don't have any 6.1 heads to compare to the 5.7's. We will be using our closed chamber 5.7 heads for this build. Jay or Stu can give you more info in this area. From what I can remember is that the chambers on 6.1, are about 10cc smaller than the 5.7? We bench flowed the stock 5.7 intake at 258 cfm @ .600 lift. A pocket port on the 5.7, yielded 299cfm at the same lift. The stock 6.1 intake should get you 300 cfm, right out of the box. Our ported 5.7 should be close to 320 cfm, give or take. We'll know more next week after we test the heads. Anythin we can help you out with, let us know. We can build motors, but we can't seem to get pictures up for you guy's. I'll have to go buy a new camera, I guess.

We finally got the Ferrea valves after a two month wait. There is a slight problem with the valve sizes we ordered (more custom head work needed), but I believe Denny has worked that out with the supplier. Here are the custom Ferrea, heat coated valves. The intakes measure 2.08" and the exhaust's are 1.62". Stock intakes are 2.00" and exhuast measure 1.55".

It's a brand new part number. They just made it up yesterday. Just kidding! Kidding aside, ATI will only make an underdrive and overdrive pulley for the Hemi application. We have the 5% overdrive pulley for our supercharger application. I don't believe they have the 10% underdrive pulley built yet. Give them a call and put some pressure on them.

I notice it has a woodruff key slot. You gonna machine the crank snout to accept one?!? Sure would give you peace of mind that the pulley would not spin under high boost

BTW a beautiful piece of work!

So just out of curiousity, why are you are doing all of this to a 5.7L when you have a 6.4L in the shop? I think it would have been a lot easier to swap in a 6.4L and then add the SC with the 8-10lb boost. Just my observation. After all the 6.4L already makes 505 hp! A little porting and polishing of the internals would easily bring 540 or so, then add the SC you should be pumping out 700+

I'm interested in the slicks and some of the 6.1 parts, I sent you a pm. Let me know what you have left and how much you want for them, please.
