2nd day of cleaning block halves. First half given its final hot water wash. 2nd half given its bubble bath to clean oil out of it.

Run a bore brush down about 20 push rod tube to clean dirt and rust out. Mounted bore brush on battery powered drill. Sure made it easy to get tube IDs clean.

Here are a couple of photos of my redneck bubble bath tub for cleaning parts. Electric heater also used because the turkey fryer burner has a 20 minutes timer. I never get back to it time to reset timer before it turns off the gas. Electric heater gives me a breather.

You can see a copper line going into the tub. It is connected to air compressor to create agitating bubbles in the tub. Helps remove dirt & grime as it gets loose.

Tom sent a photo of my heads following his weld process on them. They are looking good. Guides removed following this picture. He says fly cutting is next.

I should be receiving my parts order from Clark's late this week.

Christmas has arrived early. Santa had Clark's make the delivery. Time for me to get the block final clean completed and start the check process.

Thanks, Mike. Looks like the mod will be impressive. Can't wait for the dyno test after I get the engine broke in.

Al, don't build the engine with tight clearances..... they eat lots of HP for thousands of miles...

Matt: Thank you for the tip. We will watch the clearances. I will have my friend (Vair Guide) helping me when the block, crankshaft, camshaft, pistons and cylinders are assembled. He has done a couple of engines.


To all, I hope we beat those HP numbers when it is completed.

Upgraded my bubbling wash tub stand this week. It now has its own burner. No more running to see if the fire went out. Redneck engineering again. I got the stand from the recycle yard. The burner from AgriSupply.

ps; I am not a welder and do not own welding equipment.

Tom has provide 2 more photos of the progress on the Big Valve mod he is doing on the heads.


Chamber area: Flycut went very well. Next I'll fit each head to the valve guide fixture. Will be machining the new intake guide bores.


Next step. This is the start of changing the intake guide angle. The first hole has been opened up with an end mill. Now I'm ready to ream the hole to size. Once all the guide holes are finished I'll get after the custom guides.

Great project! I would love to see the completion. I'm located about 60 miles away in McIntosh County. If you need an extra hand let me know.

This week I did not get to it much except to collect all block bolts together and to look at it.

2 lawn tractors and a 50 ft water line beside the garage needed my attention.

I will start again next week. Block is cleaned and all passages cleared. Time for measuring cam bearing diameters.

Adding info on transaxle build to this engine build. Just to keep it all together.

Mike Levine stopped by today at my place in the country. A short visit but informative.

I learned the 4 spd I bought 4 years ago (as a newby) is a 3 spd. However the MT I got out of a scrapped 67 vert last year is a 4 spd.

Both differentials appear to be 3.27 by code letters, but Mike will confirm what gears are in them later down the road.

Mike has taken both transaxles with him. The plan is to use the best from both to make a great transaxle for my 110 Big Valve head engine.
