Engine rebuild on a 2.7 weber carbed engine and the pistons used 8 years ago are fuel injected pistons and I have gotten a few opinions of the type of piston to use by none are
definitive. Any ideas? thanks zac |

My 2.7 presently has Mahle cylinders w/ JE pistons and DRC cams and that's worked out well. I wanted to upgrade to Mahle Motorsports pistons and get the C/R up around 12:1 vs 10.5:1 but that would've further blown my schedule and budget at the time, as the existing P&Cs were OK to reuse in the last rebuild.
