Thank goodness for guys like 12Bolt Tom. Not much love for the inline 6 in 2023, but guys like Tom keep us moving down the road

[@jonathansparks3386]

This guy along with the Aussies don’t play around when it comes to building 6-cylinder engines

[@jazzmaned]

Great video Tom. It's good to see you doing great work and showing us how it's done. Thanks.

[@telowe2000]

Thanks 👍

[@RS-rn4ox]

Tom, thanks for sharing this information. I love seeing machine work on lines. A roller setup is on my list of wants for my 65 Malibu Wagon.

[@telowe2000]

Glad to help

[@davidparkin9017]

I have a distinct impression that common i.c. engines in the near future will be inline six cylinder with displacement of approximately between three and four litres producing between two hundred and fifty to three hundred and fifty horsepower.

[@buckykattguitar]

I'm now in the planning stages to build my 68 nova. A roller and a lump port kit will be part of it. I'm hunting a set of sidedraft weber intakes now.

[@telowe2000]

They are around, more are sitting on benches than bolted on.

[@Joyselcamino]

Love the video Tom. Definitely on my bucket list for the little turbocharged 250 in my nova. A set of lump ports and the roller cam would make a big power increase with the boost behind it.

[@VinnyMartello]

With or without boost you won’t regret the lump port.

[@CeeJay1941]

Nothing quite like a helpful tip from Tom!

[@telowe2000]

There is a never ending supply , just ask.

[@CeeJay1941]

will do 😆

Back in the 70s I knew someone that was a good welder. Plus had a machine shop. Welded 1.98 heads together and filled in the head bolt holes and re-drilled them to fit the I-6 pattern. Also bored the I-6 block to fit 350 pistons into it. I believe it was once in a step van. Then raced it on dirt track in a Pontiac tempest. .125 inches overbore. It was about 311 cubic inches. AS for HP and torque? Also used a Clifford Engineering cam, hydraulic lifters and a homemade exhaust manifold and intake. Probably close to 300 HP. Torque? Oh and 2 cylinders lighter. The other drivers wanted it banned. I do not think GM wanted a 311 inch cross flow head I-6 in the 60s or 70s. "Wouldn't you rather have a V-8?" GM does not put I-6s in passenger vehicles and pickups now because they are 2 cylinders too long. Might also be because they last too long. He said it ran longer than the three 350s did the season before. I like the Atlas in my T-Blazer. When 1st got it. I needed a tach to tell if was running. 21 years later and 200,000+ miles still running. I am curious as to which last longer. The frame or the motor and transmission?

Sou do Brasil, seu conteúdo esta de parabéns! Muito bom a explicação! Aqui temos muitos chevy 250 porem poucos são roletado. São poucos aqui no Brasil que sabem montar roletado, baita aula sua 👍🏼

[@wilmarjunior8945]

Use o tradutor amigo, americanos não ligam pra comentários que não seja na língua deles, principalmente por se tratar de um canal americano. Apenas uma dica, 👍🏻

[@wymple09]

I've done the lump port kit, and probably won't go to a roller cam. If I do this is the info that saves me😍

[@EBthere]

Thank you Tom.

[@lazyhoundracing9621]

Nice video Tom. This is Mick. I hope you are doing well.

[@chuckg9805]

Thanks Tom, I was wondering how ya did that.

[@telowe2000]

No problem 👍

[@mnice59]

Thanks, how about a link to your store with prices, specs and performance.

[@telowe2000]

Thanks for reminding me! Done

[@mightyeagle]

Maybe a better idea would be to tack the washer to the back of the cover

[@poedameron8198]

Can you make the same conversion on a Ford 300 inline 6? 🤔🤔

[@richardbilbruck7241]

If you must machine the block for tie bar clearance, why not just slot the lifter bore? Or is there an issue with that?

[@braddenning1617]

I could do that without taking the engine out, ! and with a 12-bolt timing cover ,i could do this conversion in a day or two ! How much power does a roller cam add ? BTW Tom , Got myself another real good stock 292 , We are going to build a 2nd one , Although mine now is making great power , Im thinking on the 2nd one we can work the crank, .how much weigh can we take off , knife edge or round the counterweights ,I want to do something wild but streetable ,but no EFI or turbos,The goal is 425 -450 HP. We will chat later on , Thanks for all your help too

looks like nobody cared

[@douglaslarson631]

I'm always interested in straightsixes

[@mikebell9166]

You need to get Leo Santucci's Chevy 6 book; either one is good, but the 2nd edition has more info. You have v8 type numbers that you're looking for, but trying to do it with a 292 6 cylinder. You may need to adjust your goals more in line with the reality of a 6. The 4200 Vortec can get you there, but you'll need to decide how much money you want to spend. It ain't gonna be cheap, or easy, or done over the weekend. Sorry. That's the way it is. Get Leo's book and do some research. It'll be the best possible 1st step for getting some pretty impressive performance out of the Chevy 6.

[@TheArchiecat]

looks to me like your not holding the drill at the right angle, not square with the block.

[@michaelcouey1383]

Hey Tom, we're getting ready to go through this part of the project. I bought a set of your aluminum finned side covers from a guy who said they wouldn't fit when he went to the roller lifters. Can you shed some light on that? I'm wondering if it's in the HEI recess where problems lie, or...?

[@telowe2000]

You need to either call me or email me. Why contact like this on YT?

[@michaelcouey1383]

@@telowe2000 sorry. I thought it was relevant to the clearance issues that need to be addressed by roller lifters, and perhaps others might benefit from the information. I have emailed in the past with questions, but hadn't received a response. I saw you were answering questions here, and like I said... I thought others might benefit from the info. I didn't realize it was going to cause you consternation.

[@telowe2000]

It is a lot harder to answer on here. I can't post pictures for 1. A modification needs to be done to the lower dist pocket.

[@OAKdust]

I emailed you a few weeks ago. Regarding motor mounts and never received a reply?

[@stellingbanjodude]

Have you ever tinkered with or modified a cross flow head for these engines?

[@buckykattguitar]

Is there such an animal? That would be the ultimate performance part for an inline

[@stellingbanjodude]

@@buckykattguitar I’ve actually made one out of 2 late model LT heads. The camshaft is what has held me up, no one would make one for me reasonably, cheapest price I got was for $2000 just for the core.

[@ostrich67]

@@stellingbanjodude Did you call Delta Cams in Tacoma, WA?

[@stellingbanjodude]

@@ostrich67 no I didn’t , never heard of them.

[@ostrich67]

@@stellingbanjodude They've been in business since the '50s at least. They custom-grind and regrind cams and even lifters of all kinds. They have a KZbin channel too.

[@GIITW.5OKC]

Why not have the pilot set the depth? So once it bottoms out you're at the correct for these lifters. I'm new to all of this and I'm kind of diving in the deep end rebuilding a 292.

[@telowe2000]

If you watch later in the video, I show lifter bodies rubbing the outer water gasket. It only happened on 2 cyl. The castings are far from being perfect.

[@GIITW.5OKC]

ahh gotcha! I thought they cast the section then drilled it.. Nope, guess not.

[@andreluis90969]

Do u know if there's good street camshafts, around 210-230 @0.050", compatible with roller lifters? I found only high duration, competition shafts, unsuitable for street.

In todays time if its not a roller camshaft its junk! Roller camshafts are now mandatory

[@PedroReyes-pr5er]

I think that will weaken the block , for all that I will stick with my regular lifters !....

How on earth would that weaken the block?
