That seems like a lot of work for the timing gear. Is there no other/better timing set available?

I had forgot to mention the prep I do so that the replacement dip stick tube will actually fit in the block. I bought a batch of these through Omix-Ada #17424.02 and they are slightly oversize compaird to the original ones. So, before I even take the block to the machine shop I drill the hole in the block for the dip stick tube out to 11/32". Then, I grind the first bubble off of the tube and the second one down a little bit. If I don't do this, it is almost impossible to drive in.

I sandblast the rocker arms and then use a rocker arm shoe kit like the Sealed Power #MR-1909 . I had measured the base circle of the new cam and compared it to the old stock cam and they were close enough so I was able to use the original push rods.

It runs!

Now, I have to change the oil, re-torque the head bolts, and figure out how to make this all work.

I just have to mock up the York Compressor Kit and she is ready to crate!
I like the look of the cast aluminum powder coated intake and rocker arm covers. Has a serious look to it.

Did you know? Willys is just Willis spelled differently, but pronounced the same. Neither Willy nor his apostrophe are involved.

Hi Rick,
Great job! I was already fascinated by your first "budget" build.
Now I am getting closer to my own build. I could get a core 360 with the right heads to use the 343 pistons.
Some questions I have, just to know what I need to order:
- Have you used new bolts on the rebuild or did you re-use the old ones?
- Same with the valve springs. New or used dones?
- what is the difference between the cam in this build compared to your preferred 268H? This one has better torque at lower RPM, but less HP at the high end?
I am not looking to build a race monster, I just want the engine to perform according to its possibilities.
Other parts I will be using as I have them on my engine:
-Edelbrock Performer intake
-Holley 4 barrel 600CFM
-IMPCO 300 Propane system
-Standard headers, but Smog "humps" are cleaned
-2,5" dual exhaust
-MSD 8523 Ignition
Thanks!
Robin

- Have you used new bolts on the rebuild or did you re-use the old ones?
I use the old stock main bearing cap screws and head bolts after inspecting and cleaning. I replace all of the rest of the bolts with new grade 8 or stainless. - With the exception of the stud/bolt that the power steering pump bracket mounts to.
- Same with the valve springs. New or used dones?
Most of the time I replace the valve springs to match up with the cam. I might use the original ones on a stocker if they look good and check ok on a spring tester.
- what is the difference between the cam in this build compared to your preferred 268H? This one has better torque at lower RPM, but less HP at the high end?
Most of the time it is personal preference. According to the specifications the 268H is geared toward more mid range but I have found it to work well at the entire rpm range. In this build, the cam came as part of the kit so there was no other option. It is the same as the Edelbrock Performer cam. The Performer cam sounds like a stock cam with no lope at all. The 268H has a nice little lopedy lope at idle.
The is my little cheat sheet for cams.
