The KC Brodix is a very nice head. the 210 would fit nice with a 427. The AFR also is a nice head.

In the short time I had the 393 on the road, it sure drove nice and seemed to make good power.

The shop that built the motor used the wrong camshaft thrust plate resulting in excessive endplay. The cam and distributor gear were wiped out in less that 175 miles. I saw that he tossed in some used pushrods when he built the motor so I figured I better check everything. Crank, bearings, pistons and cylinder walls were undamaged. Measured all the clearances, CC'd the heads, etc. Everything checked out as per the build sheet.....except for the used, mismatched pushrods which were .080" too short, one of which was bent. That pretty much put me over the edge since by this time I had missed out on all the summer cruises, etc. I replaced all the damaged parts in the 393, a friend made me an offer on the motor to replace the 347 in his Mustang, so off it went.

We have two of Keith Crafts 408W in our club. They make 530 plus hp and 540 plus tq. Coach Mike has several thousands of miles on his, three years of driving year round. No problems. Very street-able motors, meaning they idle correctly, do not over heat, no oil leaks, no problems. Just drop in and drive.

I picked up the last motor a couple of weeks ago. 408W 531 hp & 540 Tq, cost $8375. If you will add up the cost of the parts your going to buy and the machine work, you will spend close to $8000. Keith uses parts that he has proven will work.

His shops are clean and orderly. He has all the machines needed to build a motor. We have five of his motors in our group and everyone loves them.
I can't say enough about the horsepower and dependable of his motors.

Check him out. Keith Craft Performance Engines
