Performance Weber idf

Rebuilt Performance Complete Engines w/ Weber idf Carburetors

To build a quality engine, you must start out with a good case. After disassembling the engine the case is washed, inspected, align bored main and cam, and case saved if needed. Thoroughly clean again, then install original main and rod bearings onto a reground or polished crank with a German gear set.
Install an inspected set of rods, cam bearings and a good cam. Install a set of matched reground lifters. Use good German sump plates because they are a lot thicker and stronger than Brazilian.
Fit it with a new sump screen and gaskets. Install a surfaced machined pump and cover.

After all the head studs have been installed, check the deck height and c.c. both heads. Then setup a compression ratio that will run on regular gas 7.5:1.
Clean the new pistons and cylinders, of any Cosmoline and apply oil before assembly.
Install the pistons and cylinders, deflector tins and heads before the sealant dries, with new pushrod tubes and red silicone seals. The heads have been thoroughly cleaned inspected for cracks and sunken seats. Then run through our Shot Peen machine for superior cleaning.
The valve seats are then cut and the exhaust valves are replaced with TRW valves. The heads are
fly-cut and matched to be identical. After the heads have been installed pressure check the heads on the engine to make sure there are no leaks.
Install German rockers and pushrods and adjust the valve lash, spray the rockers with a special lubricant so
during start-up they do not run dry. Install valve covers and re-bend the bails so they will have the same strength as they did when they were new.
Install a good red German Elring flywheel seal and set end play and torque it using Loctite.


All of our complete engines have all New parts, unless otherwise specified.

When we talk about “exchange” that means we need your old engine from your car.
After removing and disassembling all of the parts that bolt to the engine itself, this is the part we need back. This is also called a core long block.

There are a couple of different ways to return your core, we will explain the best and cheapest way to return it. Click here
