Ask Ed Ep 10 - REV KITS, Cams, Lifters - Ed Smith w BarryT

[@jeffhill3681]

Never understood why everyone quit running rev kits on aftermarket rollers with std SBC 23* heads. ( Never could afford rolled over heads so I don't know what valve spread or angle makes it impossible) Keeps the lifter in the bore to prevent loosing oil pressure to the rods if valve train fails. The lower pressure valve spring is a big money saver in valve and seat life. The factory roller retainer in LM SBC blocks performs the same function.

Just when ya think you know something, Ed teaches ya up! Love these videos

[@BarryTsGarage]

Awesome 👍🙏

[@marioncobaretti2280]

Thankyou Barry, i love watching anything involving ed smith

[@BarryTsGarage]

Thanks for your input! 👍👍🙏

[@95Sn95]

Man ed knows his stuff I would love to work with him you would really learn invaluable information. He has so much actual knowledge of performance vs nowadays so many think their gurus because they can pound a bunch of boost to an LS and make 1000hp. Making HP nowadays is effortless it just requires money vs having to bring power from factory parts, making an old school stock block hold together at big numbers takes talent. Ed pink said he could make fatory big block Ford's hold together at 1800hp for about 7 to 8 passes.

[@shotsrodder]

Love listening to Ed 😎 what a fountain of knowledge 👍

[@keithtobin5369]

I love to hear all the wisdom thank you so much for this show

[@BarryTsGarage]

Thank you - your comment is appreciated 🙏

[@philosborn1840]

I would also run low tension valve springs during camshaft break- in on a SBC, then switch over the springs later.

[@carlpreston1680]

I still use those GM tool steel foot lifters they are still available from most performance parts stores

[@keithwarkentin]

Hey Barry very interesting episode I would love to hear Ed talk about carburetors especially adjusting the high and low idle and adjusting multiple carburetors. That is if you haven’t done a video about carburetors already 😀🇨🇦

[@BarryTsGarage]

Great suggestion! We’ve touched on carburetors here and there, but never very much as a specific focus, so I will ask Ed in the future episode thanks Keith!

[@craigbrown603]

Best info well said great show

[@BarryTsGarage]

thank you!

Chrysler Australia in the 1970's when they were racing the Valiant Chargers in the Australian touring car series and in the Bathurst 500 with the 265 ci Hemi 6 cylinder straight 6 used to turn the pistons around to get more power . These engines used to put out over 300 hp , they were fitted with 3 weber side draft carbs .

[@BarryTsGarage]

Very cool! 😎

[@PeggyParrow]

It also allowed you to run a more agressive cam lobe !

[@genxunclekey]

Great, we need to get this knowledge recorded. Everybody grab a camera and go talk to the old experienced speed shop guys

[@ziggassedup]

Cheers Barry...I knew Ed would have used Rev Kits...I built a 383 SBC for a sprint car with a Rev Kit...It made 780HP to the crank and we spun that baby to 9000rpm all the time...I have a vid called 780 dead horses showing that engine and everything inside it...It died when the new owner dropped a nut down the intake.

[@BarryTsGarage]

Wow very cool - so thanks!! I’ll have to check that out. Also, never drop things in the intake!! 😮

[@ericuncapher9922]

Best car show on the web!!

[@BarryTsGarage]

❤️❤️🙏

[@mrdanforth3744]

A lot of flathead engines of different makes had mush room lifters with a wide base and smaller stem. All were solid lifters, when hydraulic lifters came in they were one diameter.

[@Sublimethoughtswithnathan]

Would love to hear his thoughts on piston knurling

[@BarryTsGarage]

I’ll ask Ed! I’ve never heard him talk about that

[@godsowndrunk1118]

Mushroom lifters were the next best thing to rollers....

[@jeffhill3681]

Machine work makes mushroom lifters more expensive than rollers. Only used if roller lifters are not allowed by the rules.

[@ericdanielson1138]

Mushroom lifters were used on VW aircooled engines and still are to this day as far as I know.

[@ericstalker7973]

You guys answered my question in episode 10 about the mushroom lifters. Thank you Here is another question for master Ed, has Ed ever used shim stock under the rod bearings to bring the bearing clearance back into spec. We called that the poor man's engine repair. I believe my father used to do that with his race car engines back in the late 60s earlier 70s he would put the rolling assemblies together using all used crank shaft and bearings

[@BarryTsGarage]

I think that’s a good question, we talked about that a little bit related to Babbitt bearings, but I don’t think we’ve talked about that. Insert bearings… I’ll ask Ed…👍

[@obbyjep7597]

Learn something every time

[@BarryTsGarage]

👍👍🙏

[@chucksmith7166]

Also rev kit will keep the lifter in the hole if you bend a pushrod or break a rocker arm, if the lifter comes out of the lifter bore you lose oil presser and out goes the rods out the side of the motor!!!

[@BarryTsGarage]

That’s impressive. We didn’t cover that. Thanks for your comment.

[@keithbarron3654]

Used to run ported vacuum so that at stop light the engine wasn't trying to push over brakes, slight throttle you get vacuum advance that helps acceleration from light.

[@BarryTsGarage]

Very good 👍

[@doyourbest7655]

Wow !

[@RussellCompton-fh3gr]

i still believe in rev. kits ,, i think it also helps fight push-rod flex

[@clemzahrobsky2137]

H / D MC engines used roller lifters back in the 30 s

[@approachingtarget.4503]

Welcome

[@winters4q]

Can you ask ed when he drills the 3 main bearing holes bigger for oiling does he also do the cam bearings?

[@BarryTsGarage]

Yes I’ll ask Ed in an upcoming episode!

[@purplemonster2028]

What is eds favorite motor and why ? the videos are awesome a lifetime of knowledge !

[@BarryTsGarage]

Great question - I’ll ask Ed in a future episode… 👍

[@Tallbike]

What company made that 69-70 C10 toy on the shelf over his shoulder?

[@BarryTsGarage]

I’ll have to check next time 👍

[@Tallbike]

Very cool don't think I've seen one before​@@BarryTsGarage

[@95Sn95]

It bugs me when people put a roller cam next to a FT cam and say you can easily see the lobe it has so much more duration on the roller. That is not the case, that shape is not determined by the duration it's physics, a roller has a tiny contact patch a FT has a big one, small tip big lobe big tip small lobe. If you put a roller and a FT with identical specs the shape of the lobes are dramatically different roller is squarer FT is pointier.

[@RodneyHayes-d3y]

Have Ed explain the old flathead full floating rod bearing inserts before the single rod inserts came out. I'm sure a lot of people have never seen them

[@BarryTsGarage]

Sounds like a good suggestion, I will ask Ed, thank you

[@michaelgiglio1571]

Hey Barry, Mike from Au here. can you pls ask Ed why not use rev kits with flat tappet lifters and where can I get a kit for a 351c.

[@BarryTsGarage]

Hey Mike - I’ll ask Ed 👍
