I’m inspired!!! I have a 350 4 bolt main roller motor with Brodix Heads in my 85 Chevy. I don’t want to do a LS swap and pay $10 grand. I would rather turbo what I have in spend way less and get power gains. I’m pumped up!!!

[@JJsSpeedShop]

It’s been a fun project. Unfortunately I havnt touched the car in a few months due to how hot of a summer we’re having in Florida. Not very enjoyable.

[@pbettselectric134]

Great job and info. Looking into the Amazon fuel set up reg, e- pump, filter etc.! Thank you

[@JJsSpeedShop]

Glad it was helpful!

[@marquesehanley6792]

The oil drain line into the block off plate was genius! Definitely going to do that. Dont have to take the oil pan off now.

[@JJsSpeedShop]

If you plan on welding at yourself, just take your time and don’t apply a lot of heat because it will warp the block off plate if you plan on purchasing one, Moroso actually sells one.

[@marquesehanley6792]

I have a plate on it already and if I do mess it up I can get another for cheap. Appreciate the advice though. Going twin turbo on my 350

[@sbcperformance413]

Good to see that those $30 fuel pumps work. I'm running a Aeromotive A-1000 on my blazer. I bought my Aeromotive pump back in 2012, still works perfect to this day.

[@JJsSpeedShop]

Yeah, that’s definitely the way to go if you can afford it I was just trying to see budget wise what I could make. I honestly didn’t see it all working out. It was more of just a learning process but the pump has been awesome. The fuel tank is actually the original fuel tank so it does not have a sump so it’s actually picking up fuel from the top and the pump still does it with no issues.

[@sbcperformance413]

@@JJsSpeedShop Yeah man, the A-1000 is really expensive, especially these days. On my next low buck turbo build, I'm definitely going to get one of those cheap pumps, now that I know they will work. Thanks for the info and have a good one.

[@robsdeviceunknown]

Holy cow, when you got to talking carbs, I was so lost lol. I'm old school but never got much into building or modifying carbs.

[@JJsSpeedShop]

Most of it is stock specs but I get a ton of questions about it so I figured I’d just name off exactly what I have going on. I appreciate ya watching!

[@carlinshowalter1806]

Watched this and I'm getting pumped up to get my twin turbo 283 put together for my 75 Camaro! I'm trying to go low budget but the shortblock is getting forged pistons and a forged crank and a solid roller cam so it will hopefully stay together for a long while.Can't wait!

[@fiddlinjazz]

I'm thinking about doing the same with my 283. It came out of a 57 bel air. Let me know how your build goes

[@Thumper68]

Boost into vacuum advance line probably just causing timing to not advance all the way so that’s probably why it’s held together and works fine.

[@JJsSpeedShop]

That’s exactly my theory. So far so good.

@@JJsSpeedShop awesome! Check out NeoMustangs he installed a turbo on one of his foxes using stock ECM and no tune. Just locked timing and a FMU for fuel pressure.

[@JJsSpeedShop]

I definitely will! Thanks for the info!

[@jdrods1519]

@@JJsSpeedShop yes sir!!! No problem!

[@nickjones7412]

Hei timing from the vacuum advance is only moves one way unless modified. It can not pull timing under boost the linkage hits the cut out and can't push backwards. You can cut the pod off and flip it , the rod and springs then it will work backwards pulling timing for boost but will no longer advance timing. You can pull 5-7 degrees under boost by flipping and modifying it. Only person i have seen do this on KZbin is Tony Angelo on his Cheap Syclone build. Im using it on my hei supercharger setup.

Nice job.

[@shoominati23]

I wanna do a turbo build with one of the $1200 Speedmaster 350 blocks. Other people have made over 1500 at the wheels with them no problem, I'd have to use a Bryant crankshaft with a bigblock snout and Carillo rods. But you have to spend money when you're making that power level, there's no getting around it

[@stevenbelue5496]

I ordered one of the speedmaster 400 blocks from summit. I got the unfinished block and just measuring with cheap fowler mics and bore gauge it's very close. Close enough that I want to order some Starrett or mitutoyo where I can get down to hundred thousandths or at least one ten thousandths vs half a thou with the fowler. You can guesstimate with the fowler but still each tick on the gauge is half a thou or at least the one I have is. But I was impressed I didn't expect what I measured(cylinder bore, lifter bores, main bores) to be that good.

I like Chevrolet and Ford they both hold up good Jeeps the engines blow up in them or the transmissions go out

[@Headsup9550]

Where are you located? If you would put the open plenum intake on it along with a billet wheel, properly sized T4 turbo, you'd have big block torque down low and it would make about 200hp more!! Doesn't have to be an expensive one, just ANYTHING but that gt45!! That's all we had in 2010, but they are truly boat anchors in comparison to modern billet wheel turbos!!

[@JJsSpeedShop]

I’ll definitely look into it when I decide to redo the car. I got a bunch more content coming. I am going to rewire the car and get it back to where I want it to be.

[@TheMizzlefish]

The stock vac/advance can wont retard unless you put a spring on both sides of the diaphram and have room for motion both ways, i build these out of two new accell units, you have to cut the diaphram housing off of both new units, put them together like two bowls top to top, this will hold a spring on both sides of one diaphram. Remove the nipple from one of the caps, and screw that end to the flat steel bracket.#8-32 all thread will be your new shaft that you will run back to the rectangle window, get it red hot n bend it 90 degrees. Your window will have to be lengthened to accomodate the new motion of retard. Window length and spring pressure regulates sweep/ammount of retard. Or $150 i build you one too..

[@justindarnell3307]

This is sick man! I’ve got a 69 with a big block id love to throw a turbo on, where did you get the header from head to turbo and the cross pipe? Might’ve missed that part, thanks!

[@JJsSpeedShop]

The headers and crossover came from Amazon. I think they were for a Camaro if I remember correctly.

[@slayze1634]

I was wondering what you had for a pcv valve set up? I'm getting some crankcase pressure that's pushing oil past the gaskets/seals. Can you link the video you made on it?

[@JJsSpeedShop]

I use a catch can setup

[@garycrawford6912]

I think its great, i have a carbureted 350 i just put in my truck and im studying what I need to do the build on a budget as well. I see you don't turn on her too bad and its been working just fine for you. I intened to eventually put my borg Werner four speed with it too. My question is would you suggest that Cam the 292 comp or another cam. I plan on using a set of heads with a 194 exhaust valve but its a 95 roller engine. Stock rockers and studs im gonna put older 882s on it.

[@JJsSpeedShop]

The 292 is just what I already had. If I were to do it again I would just run a blower cam. For lower boost it really doesn’t matter much. Check out Richard Holdener KZbin channel. Tons of good info with dyno results to show

[@rileypaterson7117]

is your oil dip stick popping out and throwing oil on the header ?!?!?

[@JJsSpeedShop]

No, the dipstick is O-ring and held down with the spring. It’s pushing out the valve cover gaskets because I don’t have enough ventilation. The motor is old worn out. It needs to be rebuilt has some blow by.

[@christcarscountry6870]

What regulator are you running? Don't think you said in the video or at least I missed it.

[@robertbass974]

Do you run any kind of intercooler or find it unnecessary with low boost?

[@JJsSpeedShop]

No, I don’t have any sort of intercooler on it. With a blow through set up at lowers the intake air temperature is quite a bit and with the lower boost i haven’t had a need for it. If you run E85, they say it’ll drop the intake, air temperature over 100°.

So headers are down and to the rear and they just loop together. Then off the front of the passenger header is another flange for the turbo. They came from eBay

[@harmankardon478]

as an idea to check you could run at idle with your timing light and then pressurize the vacuum advance and see if you get any retard....

[@dondownriver3464]

pretty cool ride

[@harmankardon478]

Just FYI I don't think you will be getting a retard from the positive pressure under boost of the vac advance. I think what's likely is that under boost your just getting back to base pressure e.g. 32 total with zero vac advance. which does mean your timing may be high given your hitting 11 psi. How do your plugs look? cool setup btw!

[@stevenbelue5496]

No need for the boost referenced power valve?

[@JJsSpeedShop]

Any demon Holly blow through carburetor out there doesn’t come with it from the factory. the amount of boost I run I don’t really see a need for it. I’m sure it would help some but as far as need no.

[@Gregoman89]

Did it go boom?

[@stevenbelue5496]

I figure by that he's looking to see some pretty stainless tig work, 4 into 1 with a lot of stainless showing. Nothing wrong with the Holdener budget route. I'd say your nearing the area where precautionary steps need to be taken to keep it alive. Though boost is just a reference and you may not be seeing cylinder pressures that equate from those levels, depending on the intake tract and level of restriction.
