My Katech 416 update
As you may have seen, I spun a rod bearing in the stock block. Picked up a Katech 416 shortblock...
TSP 4 cam 235/239 .627/.624 LOD intake manifold Wegner cnc heads Z28 cai FIC 650 cc injectors My tuner said its running out of air. You can see the graph flattens out mid 6k. They recommend a Nick Williams 102mm TB and a 4.5" cai.... and my injectors will support e85 so I should get the flex fuel sensor. They feel I should see 40-50 more peak hp. Opinions welcome. It runs great and pulls hard... it's an amazing short block.

Nice, likin what it does around 5300 rpm, kinda looks like a light shot of something the way it ramps up like that.

Needs a different cam
You picked up some nice torque and man that torque curve is flat. Maybe a TSP LS7 3.2 cam would help It needs a lot more exhaust duration, Its taking in tons of air but can't get it out.

Red lines are stock ci and factory injectors. That's all that's changed. This was not a planned build. I spun a rod bearing and Katech was the only place I could find that had a good short block on the shelf. I drove to Detroit, picked it up and took the heads cam and intake off my motor and dropped it in the car. Funds were not available to optimize the build.. ie cam change.
Its just a street car....my goal was to have a reliable street car that makes good power.

I wouldn't be concerned at all about the HP curve flattening out at 6500 RPMs and long as you're not gonna be trying to rev past that point. Down the line, I might invest in some PAC-1204x springs JUST IN CASE the flattening of your HP curve is valvetrain (springs) related. KW

This!!! This setup with the LOD should run up to 7000 pretty happily with the right camshaft. I guess it depends on what your goals are for final power, but getting up around 600whp should be pretty reasonable to accomplish with a still strong bottom end and decent street manners. 15-20* more exhaust duration for sure is gonna make more power and run upstairs. Throttle body is definitely going to help as well.

I agree with acammer that you might need more exhaust duration to help let the air out on the top end. If you go that route, it seems like GPI has the most aggressive grinds these days with >250 degress on the exhaust side. The SS3 or one of the SS4 cams would make it shine.
Throw in the bigger CAI and the NW 102 TB and you'll be breathing great. And of course the flex fuel sensor will help too. Way to make the best out of a spun bearing!!! Very happy you're up and running stronger than before.

Glad you are happy with the shortblock!
What size headers are you running? This could also be a bottleneck. I am in the process of building a 416 for myself, I look forward to comparing our numbers. -Zach |
