Taking the 2.7 to 2.8 or 2.9L?

Hi guys – before I assume this is a Y not want to ask if this is a path worth going down? I had low compression on one of the cylinders on the 2.7 L original engine in the 74 Carrera so I pulled it and had it stripped down. Bottom is fine, Case actually looks good, but of course I’m going to get that all appropriately machined etc.

I’ve had a couple conversations with the shop that’s doing a rebuild and bumping it up and displacement is really a function of cost of parts because the labor is going to be the same, so if I’m not a stickler for originality is there any reason not to do this?

I assume the power bump of the larger displacement along with a slightly hotter cam will be noticeable but not earthshaking, is that the right expectation?

I intend to run the original CIS on it

Thanks!
