Best carburetor and intake manifold for a 273?

The valve covers turned out great. I was curious of the plastic clips the hold the plug wires to the covers. I've found some before but they were for skinny wires. Thanks Dustin

I used the original clips. My won't "clip" together, but they will, with some pressure, push into the metal wire holders. I use the Pertronix igniter and a Pertronix 40,000 volt coil so I wanted the 8mm wires. Along with a mini starter the engine fires up in no time!
