396/375 cam replacement

Hi folks,

I am in the process of a tear down over haul of my 396/375 from my 70 Chevelle and would like some opinions... The car is pretty heavy since it has a/c , ps, pb and several other options and it is a cruiser. It is pretty much stock with the exception of a set of Hooker Super Comps ( which are flat on the bottom from hitting about every speed bump it has ever crossed and are likely to be replaced with Heddman Elites) and a Torker R-2. Car is a 4sp with 3.55 posi.

I think I will go back with a stock alum hi rise intake to better fit the cowl induction set up. I will drop the comp to about 10:1 if I have to overbore the engine , otherwise it will be the stock 11?:1 pistons and rods.

I am looking for cam recommendations and any other suggestions u might want to offer. Comp recommended an XR282HR as a roller cam option and a XE268H for a flat tappet suggestion. I want to have enough vac to have reliable brakes along with a good lumpy idle. I would like to get a power boost if possible and like the idea of the hydraulic roller cam but wonder if the extra cost is worth it. I also plan on roller rockers but I want them to fit under the stock valve covers (is that possible?).

Any help you could offer would be greatly appreciated.


edit - good info so far...anybody else want a shot?:thumbsup:

Definately agree about the intake. The factory high rise is just about the best street manifold there is. The only modern cam I have tried I wouldn't recommend for your combo but a 427 or bigger and more gear it is killer.
