solid or roller cam ????
well there are hydraulic roller and solid roller cams. a hydraulic roller is what comes stock in a lt1 and could reuse the stock lifters. a solid roller would require the purchase of new solid roller lifters. hope this helps.

Kind of a Friday Saturday cruiser! I hot rod it around showing off it's beauty but looking for that bad a$$ race car sound and make people think, damn don't **ck with that car, lol
Adequate heads, intake, quality valvetrain components and a stout bottom end would be necessary to take advantage of a solid roller. If you are only wanting to spin an engine to 6500rpm then a hydraulic cam would be best. I run a mild SR in my stroker yet my shift points are 7200rpm.
Maintenance on a solid roller application would be checking lash as well as testing your spring pressures. The frequency would depend on how much you drive. I too only run the car on the weekends. The engine has been running for over a year so I feel it's about due for a spring pressure test. You can buy a spring pressure checker from Summit. I check valves ever two or so thousand miles and have found the lash to be a bit more than I like so I run through them. Once this is done a few times it takes no time to adjust valves and I don't feel it's a hindrance.
Basically if you are going to run a solid roller it's going to cost you a bit more than a hyd. roller if you are wanting to do it right. For example, if you have a street application then you want a quality lifter. Either Comp or Isky sell "street" lifters which have extra oiling ports to keep the cam lobes lubricated during low engine speeds. Very important on a SR application. These lifters can cost at least $500.
The advantage? More torque at lower rpm (at least with my setup), even with the somewhat aggressive lobes I'm running it still sounds like a LT4 hotcam and of course the non-stop power all the way up the shift points.

From what you describe what you're looking for, a SR might not be worth the investment, especially if you're just wanting to build a cruiser. It's remarkable the performance you can get out of a HR without the maintenance hassle of a SR.
yeah dont worry with solid lifters. hydraulics are so much easier. and if you get ls7 lifters they (or so i heard) rebound faster and get rid of floating lifters. upgraded springs are a much for any kind of seriour cam. but its recommended for mild cams aswell.

An HR can is capable of making all the rump, rump you will ever need to impress people. As already said, there are plenty of options. A HOT cam might be considered close to the "stock" spectrum in that realm.
X2, look at the recent AI/LE stuff.
But I would love a SR setup in my car, just cant deal with the upkeep.
HR's can make awesome power, no reason imo to go SR because you think your fairly basic h/c setup is a max effort HR build. local buddy of mine put down over 440~rwhp on a HR setup with a off the shelf cam nitrous setup. granted this was with AFR heads and a single plane but this was also through a TH400/9".
don't get me wrong SR stuff is bad *** but it's "little qualms" will weigh differently on different people, some people have zero problems with the upkeep required and others want a car they only have to pop the hood to change the oil, what category you fit in or are closer to is all up to you.
remember your h/c setup was spec'd for a stock bore/compression/rotating assembly, using stock casting heads. no reason a hr setup with a cam more complimenting to your current setup, let alone better casting head (ported of course) with a complimenting cam, can't create even more power
