Yup.... Screw those guys.

That's one of those fck around and find out situations. They just found out.

I somewhat feel like I am cutting my nose off the spite my face but I have to give my business to Lentech for having great customer service.

I pulled the trigger on an eagle competition rotating assembly yesterday and have a machine shop lined up to get the block in spec and balance the rotating assembly. I ended up with a 347 kit like my 92 car I had before. I went this route partly for nostalgia and so I will have more wall to cut into if I ever damage the cylinder walls. I should have the engine ready to go once I get the car back from the body shop but it will probably still be a wait for the transmission.

The dart block I ordered early this week from Johnson Engine parts has already arrived. I also received the rotating assembly today as well.

I am about to order the heads and was hoping yall could double check me on something. I want to make sure I end up the the correct compression ratio. I went with the eagle 14003030 kit.
I am trying to determine if I need to go with 58cc or 72cc AFR185s for my build. I am using the Summit Racing compression calculator and just want to make sure I have everything entered correctly.

I entered the following

Bore: 4.030 in
Stroke: 3.4 in
Cylinder Head Volume: 72cc
Effective Dome Volume: -6cc
Deck Clearance: .025 in
Compressed Gasket Thickness: .060 in
Cylinders: 8

This gives me a compression ration of 9.5:1

What I want to double check is the effective dome volume. The kit I purchased has Mahle pistons that are listed as flat top -6cc. On Summit Racing's website the specs list +5cc piston head volume. Am I correct in using the -6cc for the compression calculator and what is the +5cc piston head volume?

If I do the same but with a 58cc head it puts me at 11.19:1 compression ratio. Considering I am going turbo should I go with the 72cc and .060 head gasket so I end up at 9.5:1? I will be running 93 pump gas only.

That sounds like an awesome setup. I wish you could still buy the kennebell sbf kits. Do you know how much power you are making? My original plan was to go with the cnc 195 because I thought it was the biggest I could use with the header flange on my turbo kit, but I was wrong. I'll still be able to make more than enough power for my needs so I don't really mind but if I did it again I would have ordered the turbo kit with the flange for 205s.

You lucked out. Lentech FTMFW! That's who I'd have gone with if I had chosen to go auto. I spent some time scoping them out, and their staff was awesomely supportive. I believe in that company. Stick with em!

I ended up going with a ponydown turbo kkt that turned out fantastic.

I think that is the second gen 417 stereo kit. He has a more updated version now.

Chris at Lentech was excellent to work with. I am glad I ended up going with them and have also seen a lot of positive feedback on them.

I appreciate it Im really looking forward to getting it together. I had to pump the brakes on the build for about a year.

I am going to run boost control by gear with the terminator x so I picked up this CO2 tank and mac valves. The tank will mount on the cage behind one of the seats.

The rod bolts are supposed to make the rotating assembly go from being rated for 750 to 1200.

I ordered the heads and roller rockers last night so I have everything for the build now besides gaskets and the pushrods that I will measure for later.

The block and rotating assembly are at the machine shop. I should have them back in 2-3 weeks.
