I don't know anything about the aluminum vortecs, but the standard vortecs are on the small side for a 350, really small for a 400, but if you're staying at 5600 rpm or less they will be fine.

If going with a solid cam the prc108 is a cheap cam that will work very well with a 400 with a moderate port. I would also run face oiling lifters with any solid cam and with tha particular one 1.5 rockers for the street.

Solid cams as a general rule will take about 10 degrees more duration than a hyd to haved a simmilar power curve.

Btw thanks for the compliment, some people around here like me and some don't as I have no faith in anything that hasn't been soundly proven, which dismisses a lot of old wives tales and what people are sure they "know". The best thing to do when building an engine is constantly ask for explicit proof.
