Thank you Ben.

Another great video Ben

6 months later and AFR and PRO MAX have both made an ls3 head with a smaller in.valve.just what you are talking about.

5:35 I have a Buick V6 engine with zero deck height with cometic .027" head gaskets. After 3 years of running the engine like that, I had a head gasket to fail (only 4 head bolts/cylinder at 30psi of boost). The pistons were imprinting on the carbon on the heads because they were so close. One even got close enough to see aluminum. That particular piston/rod could've been an oddball length, but it was definitely kissing the head ever so slightly. When I took the heads in to clean them up, they only needed .003" shaved off. I'll be stepping the gasket thickness up to .030 or .036 next time.

I've got a 1971 383 with 906 heads and got about 9-1ratio. The cam is a factory Chrysler cheater cam which has a little over 300 duration I believe but stock lift of .450. since I have zero deck height pistons, I'm going to run a set of 1966 383 closed chamber heads. -9.5cc compared to the open chambers. .020 head gasket. I think closed chamber with flat top pistons pings less than open a chamber with a raised dome on the same octane of fuel. Chrysler called those heads "fast burn" and that's why they are expelling a lot of unburdened hydrocarbons. For a clean burn exhaust you can't go much above 8.5 compression. Open chamber heads are nothing but smog heads for their slower burn. No quenching here and no performance, but cleaner and less hydrocarbons for the catalytic converter to reburn.

What about bbf 460, they are usually around 70cc. Is that too big.

Professor Ben,that may have been the best and simplest explanation of atmospheric pressure known to man. Thank you. From off the grid in Az

The other thing with Flat Tappets,with a few exceptions, most of the grinds you see in Catalogs were made back in the 1980s when people were going completely different builds to what people expect today..

Gerat video Ben!!!!

That was confusing you said something about Yates heads SC one well you’re comparing them to E7 heads…. Where is the difference?

What brand cyclinder heads ?

Good to see you back making videos thank you for the information. Appreciate you.

BBC heads really suffer with their design... They're severely "undervalved" because of it and require some real trickery to get good numbers, from my experience. One thing I saw my friend do on a few different castings, was sink the exhaust valve (50 thou or more) so the incoming intake charge flows over top of the exhaust valve face (instead of finding it's way right out through the short side, where then it REALLY can't breathe) in the low lift/over lap phase. That was pretty much how my buddy, Nick, said it... I just tried to put it more simply... He ported heads for living, and always had some wild looking stuff over there. Anyways! Thanks a million for the wisdom, Ben!

I remember ford advising the use of the semi synthetic and the recycled oils that was on the market

Ben awesome work as always. Thank you for all your content, you are a wealth of information.

Great information about the compression ratio Ben! So would you say it ok to run 11:1 compression ratio with aluminum heads such as sbc Chevy's 113 L98 casting?

Nice video. I was taught to read the carbon ring thickness. Not too many videos on that.

Thanks for keeping it simple, we're sharp out here, but most of are not rocket scientists. Lol

Great as always, the saying for many hats offshore, is chief cook and bottle washer. Lol.

Ben what brand of cement do you use please. Kit from down under

Good to see ya back mr Alameda. Miss ya vids. mr Alameda with plugs I've noticed there resistance has good alot higher then same used plugs from 5 years ago why.? Peace

Very true. Adding the wrong additive can cause a chemical reaction and acids to form.

Sorry Ben I can hardly understand a word you're saying you really need to do something about your sound maybe a real good microphone that's up by your mouth might help I don't know

Thanks again Ben Your experience and practical proven tips are much appreciated

Thank you for sharing your knowledge with us. You have inspired my 18 year old daughter and myself to build a nice motor for her 66 mustang.

Your videos are excellent, very informative and makes a lot of sense. Thank you.

The 351W fits in there nicely. I wish that Ford had offered a 351W option when the fox body Mustangs were new.

Welcome back. Hope you enjoyed your vacation. And thank you for your service. Question,how much gasket bore size do you lose when the head gasket is torqued.

Good to see you back Ben!

A former neighbor had a 79 mustang pacecar with a 289 & fmx that he street raced & he was constantly pulling that heavy sucker out because he refused to pay someone to build him a decent transmission.

Great Video Mr Alemeda.! Thank you.

After a lot of thought, I have decided that the angle of the lobe and the convex of the lifters don't match and we know what happens.

P.S. God Bless America and our dear friends that gave all for our benefit. Thanks for reminding us.

I run a stock 454 short block with closed chamber oval port heads and a steel shim gasket. I'm guessing the C.R. at 9.5 to 1 . I ported the heads and added a 2.19 intake valve. It's sitting in a 78 nova with a NP440/MY6 4 speed transmission and 3.08 gear ratio. What cam would you recommend? It's a street car. I know you probably get this question a million times. If you don't want to answer I understand.

Your lap must be beat red at the end of this video.

Point number 1) Toss as much money you saved up in your personal junk drawer at it but don't tell your wife how much you have in it. Always tell her half of exactly how much is there. Point number 2) When you have run out of saved money try and sell gear head shit in the garage you may not need anymore constantly thinking of what can be sold without missing it. Point number 3) Dip into your paycheck to pay off the credit card bill and try to convince the wife it will be paid off pretty soon by using Point number 2. Point number 4) I'm ordering it cause I need it and I'll tell her I'll take care of it using the next 8 paychecks cause I just don't give a crap what she thinks anymore I'm going to get it anyways! These are largest most difficult points of engine building in my opinion.

Great tips and insight, Ben. As to your opening... "America, Land of the Free Because of the Brave." Thank You for that.

m running a old 428 fe on the street,it has a flat tappet cam from the 90s do you thing i need to go hydraulic roller?

There's a reason why every new car has 5/6/7/8 speed transmissions. Powerglides belong in some drag race applications and stock restorations. Everything else needs 3 or more gear ratios. Completely agree that every engine needs a stroker crank.

I think the oil weight is pretty much determined by the way the engine is built as well, what you’re doing with it. Tight clearances can use light weight oils. Big hp, loose engine need the higher weight. Plus are just driving to work with mostly or are you going wot everywhere you go! My pretty much stock 5.0 I run the 5w30 Motorcraft in the colder climates, I work at a ford dealer so it is available, and seems to work well from what I’ve seen. then in summer I run 15w50 Mobil one cause it’s easy to find.

Great video. Another topic I often wondered about reducing parasitic loss. Th350 vs th400. 8.8 vs 9 inch. Regular water pump vs electric. Wheel weight etc. I bet you would have some great tips.

Great video Ben! AG

They're taking away our freedom of speech they're taking away our second amendment we are not a free country no more. So sad we're letting this happen to our country. Other than that you make some badass motors.

What an amazing way to start a video.

GLAD YOUR BACK SAFE

Thinner oils today... for street, I am leaning towards something more of a marine style not seen on small engines: a prelube pump. Requires pan modification for the pickup and a check valve to prevent backflow [wherever it ports into the block], but purging galleys for 20-30 seconds before firing after sitting overnight or longer may yield good long term benefits. 5w doesn't worry me too much but these 0w oils do - scuffing mains seems to be happening too often - clearances need germanic precision or there will be trouble. The present obsession with anti sludging detergents [calcium dosing etc] by formulators has yielded a new problem: that old school sludge tendency [often aggravated by colder thermostats] is still better than losing film thickness and experiencing startup damage. Racers/drifters with an accumulator? Electric solenoid to dump captured volume to the block before crank could serve the same purpose.

Amen Brother! Glad to see you are well!

Good to see you sir. I am glad you made another video sir. Did you get your KZbin account straightened out? Great info sir!!!
