S10 gets new headers

The S10 gets new Lemons headers. I talk about what you have to modify and costs. Expensive

[@TPVPRO]

You can see the difference in quality with your headers. They look nice.👍

[@waynetessier3058]

Really I don't think the pipes look nearly as nice as my Headman Hustler fenderwells.

[@8power857]

Rather than dumping into one big straight collector the merge and choke then taper out to main collector diameter holds gas velocity after the exit of the primary pipes and thru the choke then the following taper out to the collector is (enter head porter term) providing great pressure recovery to keep gas flowing properly. 👍

[@paullutherborrow637]

A spacer will be ok if you get them machined to match your Center accentric hub and wheel centre ,so it actually sits on the hub and not just the wheel nuts holding it centred

[@tomv7552]

That restriction point acts much like a 2 stroke tuned pipe, sending the pulse back to the valve and pushing that little bit of air fuel mix back in to the cylinder. That same pulse event also helps evacuate the cylinder of exhaust gases

[@michaelmerrill589]

Thanks for the information on Lemons headers I Talked with Mr. Dan Lemons on the phone nice and well Educated man.

[@drivinwithdrew7676]

You would like a set of proper v bands on the exhaust some much faster and easier to install and remove, I’ve had good luck with them sealing good also! I hope it at least breaks into the 10s now!

[@DChrls]

I believe the benefit from the reduced size outlet is from the venturi effect. What happens is the gas speeds up through the smaller section and increases flow. It also cools the gas some; on the outlet side. The size of the venturi matters because if it's too big you get little to no benefit. While if it's too small you get a choke point. I would love to see if a venturi would be beneficial in intake runners and if it is where is the best place for them in the runners.

[@therocketshop]

check that the upper A-arms don't touch the headers under full up swing. This can happen when you come down from a wheelie. It happened to me on a BBC 81 malibu. Made a hole in my Lemons headers.

[@waynetessier3058]

Eric are you familiar with Swain Tech ceramic coating, it's not the cheap paint type that's applied 1 to 2 thou thick but rather real ceramic that is applied molten that welds to the pipes approx 15 thou thick. It's called White Lightning and is rated for 3000 degrees. I'v had it on my snowmobile pipe for 7 years and it's as good as the day it was done, I will be having my Headman fenderwell headers done in it, very effective for keeping the heat in the pipes.

[@hankclingingsmith8707]

YOU CAN ALSO GRIND A LITTLE BIT OF YOUR CONTROL ARM..QUICK TRICK TO FIND EXUAST LEAKS, TAKE A 3 FOOT LENGTH VACUME TUBE AND A PIECE OF BRAKE LINE. I LIKE IT FLARED ON THE END. POKE AROUND AT SEALING POINTS, PUT THE VACUUM HOSE IN YUR EAR.

[@matthewcalvert7594]

Hey Eric I’m doing the same with my S-10 . I’m removing the suck ass Sanderson restriction and i called Dan at lemons

[@ronbo422]

Merge collectors - enter in that whole low pressure/high pressure thing again. Behind the choke point is a low pressure area, sucking on that choke point and the gas coming through it. 4-strokes of an engine are suck, squeeze, bang and blow. Down in the collector there's a whole lot of sucking and blowing going on. :D

[@hqmonaro71]

Correct my if I’m wrong, but I think merge collectors increase exhaust velocity, the same way a choke point on a jet engine increases thrust?

[@jacksonbermingham2168]

i heard if pack the exhaust away to where it needs to be in a couple heat cycles it will reset bend the pipe a little..im pretty sure the guy said wood to i was like wood. it could be a option so u dont have to bash the fire wall i probably wouldnt use wood maybe a bit of metal with exhaust wrapping around it

[@bdugle1]

That $580 must be to hire the really tiny guy who can get inside those merge collectors to weld the spike in… Beautiful headers, though! Really wish you could get before and after numbers. Those Sandersons probably cost 50 or more on that 355 at a guess.

[@harvhixx7716]

I got 1 3/4 Hedmen huslers fenderwel headers do u think be ok with my 434 sbc

[@22rockcrawler]

Cool vid. Can't wait for Sunday.

[@tomrose6292]

Had no problem with my sanderson leaking ..3/8 flange . But they are my choke point At inch n 5/8

[@Nova-1977]

Lemons headers are expensive But ! On my 540 BBC it was running 9.98 the 2 inch Headers a name brand not Hookers . With the Lemons 2.1/4 4 inch collectors the only change . It ran a 9.42 . They cost 1300.00 in 1998. Moral of the story you get what you pay for most times .

[@DirtySideGetsDown]

You definitely need to try the Sniper again with no header leaks. I work for a Holley EFI dealer doing remote tuning, tech support, etc. pre o2 leaks are the worst thing for those Snipers. I bet it will keep up with your carb with no exhaust leaks.

[@jamiebrown4322]

With tuning for the new long headers the carb has even more potential power now too.

[@DirtySideGetsDown]

Absolutely, the previous headers look like straight garbage compared to the new ones. I imagine much better track times no matter the fuel delivery system.

[@jamiebrown4322]

@@DirtySideGetsDown agree. I’m always interested how fi and carbs weigh up on cars like Eric’s.

[@the4flatgarage]

I've not tested this as of yet (it's in queue), but I have it on good authority that the right ceramic coating on hedders can reduce temperatures up to 700 degrees F. That's considerable. (I'll be doing mine in white). Enjoy.

[@waynetessier3058]

Are you going with White Lightning?

[@the4flatgarage]

@@waynetessier3058 Not sure as of yet, but will check out WL. White just looks so cool.

[@eddieb1408]

i need a set of morel lifters solid. i have shp dart block with afr220 heads

[@cathygambill1554]

Ran skinnies for years on my S-10, you won;t even notice the difference. Unless you plan on racing auto cross. Just adjust brake bias with adjustable proportioning valve

[@dwightknowles2345]

I'm interested in 1 7/8 with merge collectors

[@Mo-sf7wc]

Hello, I'd like to purchase the Sanderson from you if you still have them. If you do, please let me know and let me know how to get a hold of you. Thank you!

[@mathewboyd3746]

So where did you buy your merge collector pieces?

[@chrisgriffin3374]

Merge collectors use the venturi effect to better scavenge exhaust gas pulses...i think 🤘☠bad ass definitely

[@ttamn92]

Yup I was about to post basically the same thing...

[@JAGMotorworks]

How does an h or x pipe come into play on something like this? Or not at all?

[@dalethomas9307]

Hey Ill pick up the lifters if you still have them.

[@jaymeade367]

Can I ask why your going with a torque storm ????

[@mikasantos3774]

Eric my boy that truck is going to get up and go it's going to wake up like nobody's business you can't beat them long tube babies better Scavenging keep them videos coming

[@jasonwells2988]

Not being a wise guy by any means. But that engine on the dyno made great power. I would think it would run mid 10s easily.

[@treyrags]

Jason, what power did it make? What was AVERAGE power in the used range? That's way more important than peak power.

[@landoncummings6897]

treyrags 650 on pump gas at 7500 what I seen.

[@jacksonbermingham2168]

think u need more carby spacers haha.. good stuff

[@mybelovedson]

i agree about your headers but you should have used an Allen head bolt instead of a bolt that uses an socket not trying to put what you do or say as 99% of the time your correct

[@WeingartnerRacing]

I agree. Hindsight is 20/20 the last bolts are a pain in the ass.

[@steverathwell2173]

Best thing you can do with Sandersons is set up on a mill and machine them flat where they mate the head. They are shit as supplied.

[@jasonwells2988]

Sorry. Thanks for the videos. Always great info

[@kdeupser]

still don't like either header. Looks like you would have been better off going fully custom headers.

[@davidparker4721]

My 16yr old son will buy the old ones for his s10..

[@michaelmerrill589]

I have done alot things just because good deal letting other people know.

[@pablojanski.2559]

Oh.. you lost A LOT of power with those shorties..

[@jamiebrown4322]

Nice Eric. I’ll be very interested to see what et gains these new headers make. Not just that but effects on tuning differences. Off topic here but are you running a 383 with Dragonslayers?

[@pablojanski.2559]

Wait.. Did I hear, you spent over 2k on headers, but bought a torque storm for the 406? Eric what are you thinking? LOL.. F1a 94 at the minimum.. Love your vids brother..

[@jonathandeitrick5283]

those will scavenge exhuast gasses much better. let us know the difference. should notice it mid range hit quite a bit!

[@michaelmerrill589]

Not a s10 it is a s15 Gmc version of Chevrolet s10 both GM products.

[@triple_j5252]

I’ll buy the old headers if you still have them.

[@mk-xg2kt]

now you make the engine happy.. and happy engine responds well.my philosophy. never rape an engine. by that I mean never do anything that the engine really dislikes.header leaks and fuel injection are not a good combination. and oh how often I had header leaks, seems almost a natural law.my guess is 0.4s faster.
