Im not sure why the pic turned out that way. Holding the rod in my hand i dont see the dots or feel them. Maybe it was a reflection of some sort due to the flash.
Probably an interference artifact, from the pixels in the camera, and the hone marks on the pin bore.
A 354 passenger car block has been located and purchased. Its stock bore. We are full speed ahead now working on both early and late model hemis. Thanks go out to everyone that sent private messages on leads for a block.
Will the early hemi be essentially a copy of the previous one, or are there any changes/upgrades planned?
The new 354 engine will not be running nitro. It will be a blown gas engine only. The cam will be installed at 107 instead of 112 to create cylinder pressure. It will only have one distributor. The dual drive will be on the 426. I never maxed out the hp on gas so it will be interesting to see what we can do. Im sure the truck can get into the 8s when we are done. A trip is planned to iowa this weekend to work on the stage five heads. The guides need to be set up for larger stem valves. A higher level or durability will be achieved with bigger stems. Only the highest quality severe duty valves will live in the new engine. We are waiting for the sleeves to show up then we will put it together. We will show how to put a big nitro engine together.
Well that sounds like a hell of a truck, cant wait to see it run. I talked to my uncle in waterloo Iowa, and he said roger, aka, radar (just found that out) was the best engine builder in the country and you are in good hands with him. Cant wait to see you car run this summer. Tony
I cant wait to see your truck next summer. For those that have not figured it out mcmopar aka tony will have the 354 in his truck. Roger and i are helping him out with the engine program. We have put countless hours into this program and feel we have some unfinished buisiness to take care of. We both want to see how much hp the engine make on gas. Im predicting over 800.
Thanks for taking the time to post Brian. This is a very interesting thread! Sent from my iPhone using H.A.M.B.
Another trip to iowa is in the books. I dropped off the 354 for tony and worked on some of my things. The stage five heads i have were set up with 5/16ths stem valves. This wont work with nitro. We wanted to use 3/8ths stem valves but that would have created a big mess due to the guides becoming too thin. So we went with 11/32 nd stems on the intake and exhaust. All the liners were drilled out then the guides were reamed. Each hole needed to be indicated first. After that new liners need to be installed. View attachment 3766048 It takes all day to do a set of heads but its worth it in the end. After that the installed heights were checked out and all of the valve train components were ordered. Going to rogers place is always alot of fun. There is always alot to learn. The place is a serious no b.s. machine shop. View attachment 3766048
I assume you mean 11/32nds, not 11/16ths for the valve stem, its way closer to 3/8ths. What angle are you reaming them out at? It looks like you tip the mill head to do this. Thanks for dropping the block off.
That was a typo. Just seeing if you are paying attention. I edited it. Im not sure what it was set at. Roger had it set up he did the first one before i got there. Each guide was set up so perfect a valve job wasnt needed. The seats were just lightly touched with a stone to make sure.
Why not use the cones to center off the seat and bore the other direction? No K-Line Tooling for liners? Keeps more concentric to the seat and can do a full set of liners in about 30 minutes. Good choice with 11/32 stems more valve selection.
I will pass that along to roger. He just said he wants to do it in the mill. It would have been nice to get it done quicker.
Maybe he only wanted to spend more time with a brother in arms “mad scientists united” Sent from my iPhone using The H.A.M.B. mobile app
Quicker ain`t always better.UNLESS,it`s from the start line to the finish line. Good luck.Have fun.Be safe. Leo
This morning it was another trip. This time to jims shop. He needed the fly wheel and starter. The mid plate is being made. He needed to figure out the starter placement. Kb engines have more bolts on the back of the block. We are using them all.
Will this be pretty much a bolt in deal when you put it in the chassis or are you going to have to modify the car quite a bit for this new setup?
It will need new engine mounts front and rear. New headers. The coolant lines will need some attention. New spark plug wires for both ignition systems are needed. A new larger fuel tank will be needed due to the added cubes. It shouldnt be that bad getting it all done by spring.
Here is how I do it. It goes really quick if you have their kit. I use three different broaches to help seat it against the walls really well, ream with a AV&V Carbide Reamer, and do a light hone with a diamond hone to dial in my clearance.
