I am an outside machinist and I fix submarines and aircraft carriers so I get how small measurements have to be. we use all the precision tools (outside mic, inside mic, intramik, vernier calipers, dial indicators, etc). its crazy how you can't even see something but it effects rotating machinery's durability and function and the feel of a big ball valve or if it leaks, (obviously its a big deal on a submarine) even just. 0.0010" makes a huge difference especially on fitted bolts and bearings. I did something last night that required a 0.0000-.00006 clearance. Crazy shit

You guys have a great program.....never miss it. Torrington bearings are the most under-used bearings there are....Bravo! Have built many engines but stumped exactly how you design a cam to favor two-barrel carbs......can you enlighten us all out here with somewhat of an explanation that adds up? Thanks for all you show. The List 4412 500 cfm is a really sweet carb. I noticed that you are using a slotted spacer underneath the carb. I have found that using a 4-bbl manifold sometimes indexing the carb a little forward or back on the manifold can make over 10 hp difference and certainly can balance cylinder to cylinder fuel distribution. I've not reached the end of the video yet...have you tried that?

Yea but as long as everything is torqued down correctly and the bolts for the intake plate are in good and the chain on the engine lift is good I say go at it my family and I are full of mechanics backyard and ASE certified and sometimes both plus we have motorcycle builders and mechanics in my family so if it has wheels and an engine whether it be Ford,Chevy,and or Mopar and Japanese and Harleys,Customs,and Japanese motorcycles someone in my family can work on them and I've seen engines picked up like that plenty of times and also using a manual chain engine hoist using a tree limb to pull the engine out of the car so I say when in Rome do what the Romans do and that's use the tools that you have to work with you just have to be smarter than the tool your working with

Why does the second compression ring need a larger gap than the top ring? I thought the top ring was exposed to the most heat, therefore needing a larger gap than the second.??

[@toyotabob7535]

Gas gets trapped between the rings. The only way for gas to leave is down. It's not going up because of compression. Without extra ring gap to let the gas out, it escapes by lifting the 2 ring off the wall. A bigger gap on the 2nd ring seals the motor better. Every ring manufacturer recommends a bigger gap on the 2nd but total seal....

[@PropsandWings]

Small CC's on the combustion chambers and a much larger quench area can do that. Also making the piston closer to the top of the deck and cylinder head via a longer connecting rod does it too which makes it an interference fit engine. There are more ways than what I just listed.

no porting or polishing of the heads is allowed. HOW ABOUT GASKET MATCHING THE INTAKE AND EXHAUST PORTS? LEGAL?

[@KingJT80]

@@Welcometofacsistube and youre not supposed to. it suppose to be port matched. even the edlebrock rpm intake instructions tell you should be doing it. those manifolds on a windsor for example dont even match up to a trick flow 170 and they sure as hell dont flow as much as the head does. its should be flowing more than the head.

Nothing cheap about dirt or asphalt racing I have been racing asphalt since I was 8 and dirt once in a blue moon if you got 20 grand to blow a year on tires and parts for a full season then you can go asphalt street stick or modified racing ut costs lots of money to win races and make no money

.900 cams are about as rigid as a piece of spaghetti. You lose lift with flex. Could have gotten away with a much larger base circle, you only had a stock 400 sbc stroke........

Rules like this on the engine are stupid. Better efficiency is good for the engine. Smaller engines lower weight.
