Your attention to detail is remarkable. I really appreciate your content. Thank you for sharing these videos.
Fantastic video, I am planning to do the same things to my BBC build. Thanks for showing all of this in detail it is definitely motivating.
Looking forward to seeing the output of the rebuild!
Old timer gave me the tip to use a thick layer of clay or Play-Doh over the valve seats. Might be a little safer than the tape 👍🏻
Good idea. I did use a few layers of tape, but the best way to avoid damage was just to avoid contact.
it has been over 5 months !!! Hope you doing good ? you get more power with compression at 11 to 1 and proper cam ,shorty headers down low 5 K and just clean up stock headers ! BTW i would not use that oil guard under the manifold it will mess up your push rods ,you need a lot of clearance ! Best bet is to go with a new design manifold that has a space in-between !
Not good. 2 engine builders have said no.
@@SS454LS6 no too not using the oil guards ?
Nice ride you need to get the rid of the Air gap and get a victor jr intake.
Why do you think that?
Great vid! Can you tell me what the numbers are on that oil pan? Ive not been able to find a drag style pan like that that fits and id love to get one tor my 71!

another great video
Thanks!
Looking forward to seeing the next video. I saw you taking video at the ADL show yesterday, by chance did you get any of mine?
I did get one vid of you leaving. Your paint looks incredible this year.
Thanks I haven’t polished the car in over 10 years. Lol
Looking forward to seeing the new engine combo run.👍
Gotta get closer to your wagon!
Great video ! Who knows if those little things will make a difference , but I love doing the same . It makes it yours !
absolutely!
RR ovals
Your right. That do absolutely nothing
You should have done more. Smh.....🤦♂️
sarcasm or are there areas you are thinking could use more modifications?
@@SS454LS6 in the valley and the rear wall of the block. The cast surface really impedes oil flow. Grind it all smooth with a carbide burr and the oil will run across the slick finish.
Getting the oil back to the pan is the name of the game.
Also with your pistons, don't forget the edges where the valve reliefs end at the outer edge of the piston crown. I use 400 grit Emery cloth and polish the sharp edges away. The MAHLE piston you have is a nice piece, and you'd think it wouldn't need all the deburring. The underside of the piston could use a little TLC too.
Another critical area is the bottom of the cylinder bore. There's always a nasty edge that can catch the piston skirt.
Good work on the main caps, but don't forget the main journals in the block. Breaking the edge there is just as important.
Deburring the entire block in general is important. It's easier to handle and safer to work with. Every damn aluminum block or cylinder head these days are machined to sharp edges.....
The oil pump main cap can go deeper with the radius. Then match the cap to the block surface. They're usually out of alignment. In some areas I find my Makita die grinder cumbersome. I scored a 10 piece set of long shaft carbide for a dremel in 1/8" shank. I had to cut the length down, but they work great for tight areas.
Last but not least, always chase your threads and chamfer all holes. Don't "tap".....chase. there's a difference. Good luck.
