Exactly... 4" of aluminum.he cut the aluminum block off parts himself, made me a pair too. I have no clue what he started with but I'd guess less than $5 worth of aluminum.
Most expensive part was buying a new bushing so I can measure the OD. I thought about returning it.
All my panels vibrate like crazy not sure if it is the missing balance shaft or just ridged mounts, or both.
OK, so the Engine blocks are not exactly same. But close enough for me.
On another note.
I'm currently plumbing dual P/S pumps.
Aftermarket T/C pump bracket in the old A/C location and a stock style pump off the cam shaft.
**Note not all cams have the hex to run the p/s pump. I had mine machined and pressed in a hex, there is a GM part number for it.
I was originally going to run a MSD distributor in place of the pump. The hex press fit wasn't heavy enough for the pump (wrench test) so over the weekend I had to pull out the cam shaft and welded it in.
Plumbing should be done this week.
Would have been easier to just buy a used cam.
I'll let you know how it works after my next race.
Hopefully I will be able to steer fast enough.
Now even if I throw a belt only thing that will stop me is an eventual dead battery, since the water pump is timing chain driven.
