We Dyno A Billet Head and Make Huge Power!!!

[@jdoe9518]

First thing I'd be checking is the pushrods 1) do the the pushrods clear the bores through the entire lift range. 2) flexing pushrods create a valve bounce situation. Higher lobe lift is only part of the story. Higher ratio rockers bring the bring the pushrod pivot closer to rocker centreline. This has two affects 1) the pushrod moves closer to it's bore (higher lift also means it runs through a larger arc) 2) there is more load on the pushrod side of the valve train because of the change in leverage

New subscriber here and I really like all the new things you can do to these engines now. When I was a kid back in the early 60's my friend and I had a go kart frame but no engine and one of his dad's friends gave us two old McCullough Chainsaw engines meant for the old 50's style saws they were fairly big and pretty stout. Once we got them working in sync we had a death machine you would have been proud of. It went way faster than you should ever go on a go kart from the 60's. I am happy to report both of us lived and it started me on a life long love of working on engines. Keep up the good work! Oh and for a brake we had a piece of flat stock bent where we could lever it against the back wheel, did many unintentional spin outs because of it.

[@cmccoy3972]

My friend, I’ve never seen any of your videos before but because I am so impressed that the Lord allowed me to notice the subtle evidences of your faith, prior to the dyno test, I am writing this to encourage you. It appeared to me that the Lord is going before you. I thought, this guy is bright, he has a pleasant countenance, his shop is clean and you know there is something about him, he just may be a believer. And then, of course, the verses and concluding blessing gave affirmation to my first impression. I will be following your videos, when I can, and praying that the Lord may bless you and use your work to draw many to Jesus. For the last 52 years I have tried to do my own auto maintenance/repair, first because I had to, but now, I just like doing it. I will be watching for your videos.

​@@RedBeardsGaragewhere did you get the fuel tank from?

[@cliftonnutter2484]

With that cam and rocker ratio you need at least 50lb springs or more to control the aggressiveness of the 2. .356 cam is a aggressive profile and 1.3 will make the 36lb springs float at high rpm. Upgrading to 50lb springs and larger push rods will cure this problem.

[@brian6029]

[@peterchristlieb]

The 236 I built and ran in the drag bike has the Moflow 14cc head out of the box with 1.2 rockers and a .356 cam. I did use 1/4" pushrods but it shouldn't make much difference being they are that short. It turns 10,000 all day long with a Honda coil and the 6689 flywheel, I estimated 24hp with nothing trick or custom about the build. Maye be try boosting the coil gap, mine was set at .045 and on Gas, you should be running a 115-120 main jet, needle one clip up from the middle

[@oniefields83]

I had the same problem with 1.3/356 combo on big block. Springs and all were correct but wouldn’t turn over 7k no matter what coil or anything. After braking 2 rocker adjusters I Ended up going down on camshaft and now it goes to 8500 no problem. It seems that the 1.3/356 combo needs more valve spring than it calls for because the ramp is so aggressive.

[@RedBeardsGarage]

That’s exactly what we was thinking. I talked to a friend that builds engines as well and he has said the same thing. Thanks for the info. I think I will swap out to a .308 and try it again

[@luckyred1818]

Hey there, Red Beard! I like your shop and toys! Please give me your advice on carts. If a guy can rebuild an engine, port intakes, deck heads, etc; and wanted to spend about $500 on an engine, what would you recommend, building out an old 212 predator or buying a 15-16hp out of the box?

[@NotMeeither]

The lack of high RPM could be those 3/16 pushrods flexing at higher RPM , the reason for the 5/16 pushrods is to stop them from flexing.

[@RedBeardsGarage]

It could be but I think it’s valve float. I’m going to try a .308 cam and see what happens.

[@NotMeeither]

@@RedBeardsGarage I had a Ford 302 that I built several years ago that I put a good set of stock diameter crome molly pushrods it with a very high lift cam, it would not rev past about 6000 RPM . A friend talked Me into ordering a set of 3/8 crome molly pushrods for it and they fixed the problem, after the new pushrods I was able to shift at 9200 RPM! There's nothing like a small block Ford launching at 8500 and shifting at 9200!

[@cliftonnutter2484]

I agree with the push rods. I built a 263r with the same .356 cam and 1.3 black Venoms. I had to put 5/16 cut to length rods in due to flexing with the duel springs at high rpm.

[@cliftonnutter2484]

The flexing will make the engine feel like valve float

Are these hot engines similar to those in a drag car in that the boost in performance takes away from longevity in a significant amount? Go Tellico by the way. Lol

I think Red could have caught Lonnie with a longer run when he was on Lonnie's bike. The difference in weight makes a big difference with a small engine.

[@jacobwilhelms6779]

Thank you for the Bible verse

[@74elsinore]

Excellent video as always. I'm always interested in making more power. curious why all of your engine projects are always utility engines that were never designed to make power. Why not use a zongshen 190, cr250, crf450 or multi-cylinder sport bike engine? Seems like a lot of money for a low performance platform. I mean no disrespect, I love your videos and everyone on your channel seem like good people. just curious why the attraction to utility engines

[@RedBeardsGarage]

I just like using them in a way they were never intended. Of course it is easy to put a dirt bike engine on something and make power. We just like the whole process of building them up.

MPH don't matter. Its how fast it will get to the MPH. You can have an engine with 100hp and one with 10hp and both have the same gearing, they'll make the same mph.

It gets it. Oh, I’ve got a a juggernaut as well. It’ll hit 35 extra quick and pull to 57 about 4 sec after. That’s super difficult to justify the massive price difference. Unless you can explain. I can’t see any real benefit.
