Anybody know the base circle on this cam?
Anybody know the base circle on this cam? It's a Comp XR228/230 571/573 112 LSA comp pt# 54-428-11 I am wanting to find this out so I can order the correct pushrods at the same time I order the cam and springs. Also what is the base circle on the stock 2000 cam?
okay the stock cam radius is .775" and diameter is 1.550 ..
comp 228/230 radius is .732" and diameter is 1.463
I am using a 7.4 pushrod with a .045 cometic head gasket and heads milled .018..If using stock heads and stock head gaskets then use 7.425" pushrods
comp 228/230 radius is .732" and diameter is 1.463

2000 base circle (radius) is 19.7 mm (double if if you're gonna measure it with calipers) 01 ls6 is 19.3mm and 02+ is 19.0mm. The valves on 02+ are .6mm longer to compensate for smaller base circle (that's .02366" so 7.425" pushrods are right if it's similar to ls6 base circle....)
I am about to get a Comp XE cam also. I have 7.4" pushrods on my stock heads and cam. I am going to have the heads milled to a 62cc chamber and use a .040" headgasket. Best I can figure I will still be good with the 7.4" pushrods. Anyone agree or disagree?

My XE cam lobes measured in at 1.450 with a dial caliper.
