My 1969 Chevy Custom 10 HR

<< < (3/3)

Lee:
Yeah, moving slow on this thing.  Ordered a drop in bedliner as a cheap way to avoid messing with the bed.  It's impossible to find them for 67-72 Chevy trucks, so I bought one that is supposed to be close (95-2001 Dodge full size)  Worked out pretty decent, and only 150 bucks.  I also painted the bed sides and put new brake shoes and hardware in the rear.

Lee:
Well, the latest update on the Junk Truck......  Built up the 307 on a budget (sort of)....

Cam specs:
Duration at 050 inch Lift      214 int./224 exh.
Advertised Duration      272 int./282 exh.
Valve Lift with Factory Rocker Arm Ratio      0.442 int./0.465 exh.
Lobe Separation (degrees)      112

As built, I calculated the static compression ratio to be 10.5:1 with a dynamic compression ratio of 9.33:1. 
These numbers may not be 100% accurate, but they should be pretty close.


So far it is running great on 93 octane pump gas.


The 307 I was building was using a press fit harmonic balancer with no center crank bolt.  While the motor was out I went ahead and drilled / tapped the hole for the crank bolt (7/16 - 20).  It made installing the balancer a lot easier than hammering it on or trying to locate a special tool.  All of the loaner tools that I could find in chain stores required the tapped crank snout.

I removed the fenders, hood, grill, and core support.  This made the whole process much easier than it would have been otherwise. I pulled the motor without the tranny attached.  Upon re-installation, I found that I needed to
jack up the tail of the transmission in order get the motor to go in.

I am loving the end result.  I do not have any specs yet on actual horsepower or torque, but the seat of the pants results are enough to get 2 thumbs up in my book. It is a huge difference.  The edelbrock is a piece of cake to get setup.

I will be posting pics and hopefully video as well soon.
