I am building an 11.0 to 1 355 LT4 motor (forged pistons, H beam rods, stock LT4 crank, ported stock heads) I would like to rev it to 6500-6800 rpm. My question is this: does anyone know of a production aftermarket cam that would suit this engine and support the high rpm's or am I going to have to have a cam custom ground? Has anyone here built a similar motor with off the shelf parts? Thanks.

 

Get a custom from someone like Joe Overton.

 

Not to sound stupid or anything bvut, is that a supporting vender or something? How do I get ahold of him? Thanks.

Stock cubes here, shifting at 6800-7000rpm and it never stops pulling.
