So you left everything pretty stock but bumped up the compression a bunch. You changed pistons for sure to do that, if you didn't, you don't have 11.26 comp.
But with that said, with all the stock parts you are using there are a bunch of cams you could use. With the biggest restrictions stock intake and exhaust and 906 heads id go with a cam around 238* @.050 around .500 lift on a 108LSA. Any bigger and she will feel like a dog around town.
If you did change your pistons and have a true 11.26 , im not sure I would go much bigger then that either, because of the stock manifolds and intake. If it were a automatic with a vert, I would say you could go a little bigger.
Yes, long story short, after replacing pistons, decking block, surfacing heads, the engine builder used a thin head gasket and that's what the compression wound up at. It's had the heads cleaned up with mild porting. It is already assembled, but needs a new cam due to cam bearings not being installed correctly resulting in oil starvation. So, this is not a new rebuild. I'm keeping it stock externally. I don't know that the cam that was in it previously was the right choice given the engines restrictions, so just wondering what your recommendations are. Thanks for all the input!!
