My solid roller is 264/658 on intake and exhaust for my 482ci. Yes it's lumpy (Specialk likened it to a AA/Fueler with mufflers). Folks warned me about it--but so far, so good.

It works just fine on the street--tons of torque down low, and it just gets better as revs climb. Went through everything at the Fling without a problem (save for an unassociated issue with a distributor cap failure from MSD).

Better still, and more importantly, it stays very cool (stop and go in 105F heat results in never going past 195F), holds idle just fine, and is just perfect at cruising speeds (2500-3000rpm).

Upkeep? Same as any solid cammed engine. Yes, hydraulics are easier. Then again, a Corvette's alot easier to live with then one of these beasts.
