I finished the installation of sub-frame connectors on my 69 Camaro. While I installed them I also put in some new sub frame bushings. Both came from Detroit Speed & Engineering. Installing these SFC’s is a lot more involved then your standard SFC install on a late model Camaro. The way these are design they are virtually invisible when looking at the side of the car, unlike bolt in ones which hang about 5 inches from the bottom of the car, these follow the contour of the floor pan allowing them to be very low profile. Here’s the write up:
The first item I installed was the sub frame bushings. As some of you may know the first and second generation f-body’s came with a removable front sub frame. The car was a sort of hybrid uni-body. The front sub frame is held in with four body mounts and two that attach to the radiator core support. Here’s the kit from DS&E.
The bushing in the center is for the radiator core support the other two are the body mounts. The new ones are made of aluminum and are hard coated. They came with stainless steel washers.

This engine has been a long time in the making. I believe talk of building this engine began around 2002-2003. We had a spare 4 bolt main block out of truck that had massive oil consumption issues due to broken piston rings and bad valve stem seals. Being that it was a 4 bolt main block, we wanted to build something a little more special than a run of the mill 350. We decided a 383 would be a fun engine to build and we began to gather parts. It took almost all of 2004 to get the parts together and have all the machining done. The block was boiled, then painted with Chevy orange on the outside and Glyptal in the lifter valley. Glyptal is a paint that is normally used to coat the windings in an electric motor, however engine builders use it to make the oil flow down the lifter valley quicker. A local machine shop bored and honed the cylinders, and line honed the mains. By December 2004 we had all the parts we needed and were ready to assembly it. We added the heads and a partial valve train around 2006 and it has sat in silence since then. Below are some of the details of the assembly of the short block.
It’s based on a 4 bolt main truck block that was pulled from a 3/4 ton ’86 pick up. The rotating assembly consists of an Eagle 5140 steel crankshaft, Eagle H-beam rods, and Speed Pro hypereutectic pistons. The Block was bored, honed and painted. The mains were line honed with an ARP main stud kit installed. The bottom end is very stout, and should handle pretty much any cam/head combo we could dream of.
