If the average wrenchhead watching your videos would simply park their urge to correct you all the time, there's a lot of really great information available here.. Thanks for taking the time to make these Ken.. It's obvious you put a great deal of heart into them and I for one appreciate it!
I've seen this my whole life, a engine requires a recipe and alot has to do with what car,axle,tire size,transmission, converter, etc. Then you get into WHERE you want power to be made,ie you don't torque dropping off at 3k on a heavy street car just so you can say you have a 8k shift point. (Until you start playing with newer vvt)..on the contrary with a gutted shell you don't need monster torque and you can get that engine up into top rpm range...but this video is right on point.
Makes total sense. Start with the known limitations dictated by the size and usage and go from there. I've only built a handful of engines so far as a hobby but I do a ton of reading and what you explained is pretty much what I've also concluded from paying attention to successful pro builders. Great bit at the end too about putting HP into a realistic perspective instead of chasing numbers.
Ken, just a quick comment here to thank you for your quality content. I've watched all of your videos and really appreciate your consistent straightforward approach. Keep building, keep talking and thank you for sharing your many years of experience and knowledge. 👍👍👍👍👍👍👍👍👍👍
Appreciate this video Years ago with my dad & Brother inlaw .. We built 350 bored 60 over 9.1 Pistons , Trw camshaft 442 465 lift 288 298 duration advertised. Zora Arkus-Duntov Holly Dual plane intake 65cc camel hump heads? Most camel humps really 64 CC's or 72s All I had was a Mr. Gasket engine Dyno program on D.O.S 🤞☝️🙏🇺🇸
Love your videos! I'm not going to claim that I know a fraction about building engines that you do but I do know from experience that you're not blowing smoke. I just finished building my 65 GTO engine, wish I had brought it to you. I am happy with the build but I'm always going to wonder if I could have done better.
Excellent building points! I have a 427 Windsor built on Dart block. 10.3 comp with TFS 225 heads flowing 320 @ .600 Hyd. roller cam 241/249 duration with 600 lift. makes 480 HP and 505 torque at 5500 RPM at the wheels. I run a 3.50 rear gear with 5 speed manual in 2900 lb. Mustang LX. Runs easy 10.90 at 131 with a very easy launch and still runs strong after 11 yrs. of mostly street cruising. Built it myself and nice running on the street with pump 93 octane. Cruises great at 1500 RPM in 5th gear.
First off I want to thank you for sharing your knowledge with us! That means a lot to me. I have learned so much from you it’s scary that I think I can build a decent engine. Lol anyways hope you get this and respond to me, you had a video about choosing the proper cam shaft for your engine, you explain about how it depends on the flow of your heads and where you want the torque to be at low end or top end, anyways been scrolling through and can’t find it, would love to be able to show my son that video because he is currently in the middle of a build, anyways if you see this and could direct me to that video I would greatly appreciate it, hope all is well man
I cheat and just copy something GM did in the 70s. Heads compression ratio and cam etc. I was happy with the 442s GTOs Chevelle SS and just copy those. Your info is sound but I loved them in the 70s and 80s and still love them now.
From factory my engi e makes 300hp with 212ci. It's a 10.5 to 1 fuel injection v6. Its a Nissan Vq35gr revUp. I'm porting my intake plenum upper and lower and the manifold. From all I can tell the guys who crank big power out of these things they leave the heads alone and just add intake and exhaust mods, cams of course and upgrade the valve train ; springs & retainers then the tune and set the Rev limit to 8600rpm and they get 400 on 93 to 103 octane and up to 530hp on e85 with bigger injectors all Naturally Aspirated. I love these Dohc high rpm engines. My car now revs to 7,500rpm and its a nasty nasty street rod.
You have a good formula all my years in this I do it almost the same way but in the beginning I made a lot of mistakes usually to much cam things like that. But it is like you said at what lift do the heads really have the best flow then you can build everything else around that figure or close to it. I also built a lot of engines remember the old Crane Fireball cams for the Mopars not a lot of lift but lots of duration it was a good match for stock heads. These days though I build everything around the cam and if I have heads already that flow for example 200 CFM at .500 lift and I want to use it all then I use a cam at or very close to that. But if I just want a slight lope and more low end grunt and 9:1 compression then I wont use those heads because of the velocity loss slightly ported stock heads would be better anyway a very good video that I am sure will help a lot of people pick matching parts.
332 cu in, 10:1 compression, blueprint heads 190 runners 2.02/1.60 heads flow 250 at .550. my cam is 266hr12, not a ton of overlap but enough, of course i live at 4800 feet, weiand street warrior dual plane 1" open spacer, 600 cfm carb, it runs great, scat rotating assembly, mahle 4032 forged flat tops, machine shop machined it i built it, 1st try
My car runs great,383 big cam long tube headers etc. 4:11 rear gear and Muncie 4 speed. 56 Chevy 210. I can hit the line lockers and blow the tires off but it definitely feels like a top end kind of build. It’s got a Holley strip dominator intake on it. And being that it’s a street car, am I missing out on torque not running a dual plane in your opinion?
@@RAWRMotorsports well Hp is torque x rpm divaded by 5250 so its a very different thing having 400 hp at 4500 than 8000. So if you raise the operating rpm on any given engine you gain more hp (given the rest of the engine is made for it) A Honda 2 liter engine can make more than 300 hp NA. But its a whole different deal than a v8.. All talk of hp or torque should include rpm to actually be indicative of what the engine is capable of.

It's nice to just listen and learn,well done sir👍
I really appreciate your videos. You impart great knowledge. Thanks!
Thank you for sharing your knowledge.
Awe man, didn't know you were in MD! I grew up there, Calvert County!
That's what I said.
Ellison's I discovered is in Glen Burnie. .....Harford county here🤜
@@nealhead195 I know where Glen Burnie is! My folks are still down in Prince Frederick, MD, I've been out in CA since '90!
Appreciate this video

Just this evening I came across your channel and was happy to hear that you also are located in Maryland.

This is gold. Thankyou.
Thanks again for your teachings and sharing your valuable knowledge. Happy New Year and Cheers from Motown.
Awesome video 👍
Thanks that helps a lot.
Thank you great knowledge

Just a mixture of 11 herbs and spices and you got a fast motor lol

62-1/2 hp / cylinder? Not cubic inch??

It probably isn't well put together for torque if "big cam" means what it usually means when people say it.
What do you think about forced induction? Or different fuels?
How many times guys won't to put 230 cc heads on a sbc 350 and thank it's going to be a screamer out of the hole
At wich rpm would you say this estimate is for?
1.25xcui at 4500 vs 8000 rpm is quite a different deal after all.
🤣 1.25x400cu in is 500hp every day of the week
@@RAWRMotorsports well Hp is torque x rpm divaded by 5250 so its a very different thing having 400 hp at 4500 than 8000.
So if you raise the operating rpm on any given engine you gain more hp (given the rest of the engine is made for it)
A Honda 2 liter engine can make more than 300 hp NA. But its a whole different deal than a v8..
All talk of hp or torque should include rpm to actually be indicative of what the engine is capable of.
