Long-block is back from a local OC engine builder. This is a '76 2.7 S engine which was true.
I decided on this build because I want a high RPM carburated Peeky engine with more HP that torque. This is a copy of the 2.7RS spec. which should make around 200HP.
Case:
All the oil plugs were removed in order to clean the pasages. The bypass was done, the squirters were replaced and a 3.0 oil pump was used. Allign-bore was done. All bearings were replaced, time certs installed and new dilivar head studs were installed. The counter-shaft gear was neplaced with new. This is a commonly overlooked, but affects the cam and ignition timing.
Crank:
All plugs removed, galley's cleaned and new plugs installed. Crank was micor polished and balanced.
Rods:
Al rods checked, balanced, and small end bushings replaced with new.
Cam Towers:
Machined to flat surface. Oil tube removed, cleaned out and replaced with new plugs.
New German billet Cam Blanks ground to "S" Spec. and hardened.
Heads:
Replaced all valves with Aasco, guides with silicone-bronz. Replaced springs, keepers, retainers. CIS injector holes were welded closed and machined since I will be running Webers. Ports were opened and polished. Air injector holes were pluged.
Cylinders:
New Mahle 8.5-1 RS type pistons and cylinders.
Chain Boxes:
New ramps and chain, and pressure-fed tensioners.
