[C1] Crate engine height
The problem the mechanic is having is the vortec intake manifold, Holley carb and air filter set up is several inches taller than the previous intake which will interfere with the hood closing. According to the tech at Summit Racing there are few low rise intakes for the vortec cylinder heads. Does anyone have any suggestions or experience with this problem? Any advice would be appreciated. Thank you.
1. Did you use the 12496820?
2. If it's too tall can you return the engine and get an earlier non vortec
3. A pain in the wazoo but the vortec heads can be drilled for an early non vortec manifold. There is a fixture for doing this. Some of the holes will enter the water jacket and will need to be pugged but anyone that has done this should know how to do everything. It can be done using the gasket as a guide but you only have one shot to get it right.

The intake on the motor is 12486570. Drilling sounds risky. I'm not sure the mechanic would want that responsibility but it can't hurt to ask.
What is the height of the sp 350 intake? Is it 8 bolt straight down? The only one that came close to the 4" of the original is made by Professional Products and is 4 1/4".
