RHS LS based 502 Aluminum Block
No your eyes aren’t fooling you and this isn’t a typo; RHS has gone on the map as a block manufacture by creating their first ever block - a 502 cubic inch LS monster. The dimensions are a 4.600 bore and a 4.165 stroke that is supported by a priority main oiling system. The pan rail has been widened to take the extra stroke while also decreasing windage; all surrounding the forged main caps.
There is a maximum deck height of 9.750 and houses a spun cast iron sleeve inside the aluminum block. The RHS block will accept any five or six bolt cylinder heads. The cam is raised two links (.388) and the cam tunnel will support up to a 60 MM cam. There are even provisions in the block for dry sump system that are easily accessible.
14 Degree Race Heads for Small Block Chevy
RHS has released their Pro Elite Small Block Chevy 14 degree head that is designed for circle track and nostalgia drag racing. This is a race piece that features massive, 235 CC intake ports and are expandable to 285 CC.
The chambers are CNCed while the intake and exhaust ports remain as-cast with a lot of extra material for those large porting options. The decreased valve angle allows for a more direct shot through the valve and the ability to run a flatter piston for higher compression. Chambers are offered in 42-47 CC and are designed for high compression applications.
You can receive these heads with the as cast 235 CC intake runners, P Ports with seats and guide holes machined or P-Ports with unmachined seats or guide holes.
RHS 23 “Style” Raised Runner Cylinder Heads
This is a perfect head for classes that require a 23 degree iron head. Most rules state that there can be up to two degrees of variance in the degree angle of the head. RHS has taken full advantage of this rule by creating a 21-degree, small block Chevy head from their Pro Elite series line. These heads come as cast with 220 CC intake runners that were originally designed for circle track competition.
The 21-degree comes from angle milling which aids in increasing the airflow through the turn. You can receive these heads with the as cast 235 CC intake runners, P Ports with seats and guide holes machined or P-Ports with unmachined seats or guide holes.
