High Compression 390

If you can afford it go hydraulic roller . I myself am done with trying to break in flat tappet fast ramp cams.
That is how I got to this! I started with a simple rebuild, then started looking for a 360 block, couldn't find one then decided instead of 360 I will stoke a 318 for a few dollars more! Now look at me, for another $$$ I could do a roller 11:1 390 that will put out 400HP.
