Project Fast Fish: Chrysler 318 Stroker Build and Walk-through - Part 3

[@DvDjSpeedDemonVideoJunkies]

Following your build, great job and tons of detail. I'm building a 318 with my 18 year old son and this helps a lot.. Thank you

[@MicsMotorworx]

Awesome. As you saw in the videos, my Pop was lending a hand as well. Not a lot of things are better than working on a project with the family. Let us know how it goes.

I'm building a 318 with my 21 year old son! Its a great learning project and we're really enjoying the get together time too!

[@MicsMotorworx]

Awesome. Let us know how it goes. Thanks for watching.

So, if you are curious, Nick’s Garage on KZbin built a 318 stroked to 390. Don’t know where he got the parts but he said it’s a 4.000” stroke. Based on your bore number that’s 0.030 over with a 4” stroke. Put pretty much stock but he upped the compression to 10.5:1, ported iron heads (he gave the serial number) with 2.02” intake valves. Stock rockers & push rods with a comp cams flat tappet cam. He said he had 120 pounds of spring. Aluminum intake, double pumper carb and cast iron exhaust manifolds. He was able to get 15” of vacuum at idle for power brakes. On the dyno he was impressed with the results. 405 HP at 5400 & 445 foot pounds of torque at around 3800 on 94 octane pump gas. I’m not really a MOPAR guy, but I was pretty impressed for what is really just a daily driver. It would really be nice in an older pickup.

I like when you're parking garage down in the music starts with a click. I thought the click initially was your torque wrench but when it didn't stop I realized it was the music😅

[@GregsAirplanesandAutomobiles]

I'm enjoying this series. Well done.

[@MicsMotorworx]

Thanks. We have a lot in store for the near future. Thanks for watching 👍

[@Homecar220]

Looking good! Can't wait to finally hear it in the Cuda!

[@MicsMotorworx]

Thank you. This one is going to a lucky buyer to help fund the Cuda build. The other stroker from the earlier vids will be the heart of the 73. We can't wait to hear it as well. Thanks for following and watching 😊

[@jonathankountz7097]

Sounds good

[@MicsMotorworx]

Thank you. The new owner seemed really happy.

[@kencohagen4967]

An Edelbrock Performer Air Gap would be my choice. It’s not about having a fancier intake, or bragging rights, it’s about making power. The air gap design allows the manifold to run cooler, which will make more Horsepower throughout the RPM range. Of course I live in Arizona, and heat is a major issue here. Back east you might want a manifold that runs hotter for the winter months. That’s not a big problem for us.

[@MicsMotorworx]

Thanks. There's a lot of love out there for Small Block LA. We went with the Performer RPM on the 390. On the 349, we went with what we had since it's going to used as a fundraiser for Project Fast Fish. Thanks for watching. 👍

[@albertgaspar627]

@@MicsMotorworx there's an ongoing debate--UTG's video channel found his slant 6 needed more heat in the intake, and of course Smokey Yunick had his hot air engine design making 1.8 hp per cubic inch. the goal of cool intakes is to create a density in the air charge, and a good ram air setup will do that. Heat can cause fuel percolation, but a cool can or using an electric fuel pump and a return fuel system over a mechanical one soaking up heat from the block can do that.

[@MicsMotorworx]

Neat. I love UTG and his videos. I, for one, should never debate the finer points of chemical reactions, mathmatical engineering, nor rate of changes in density during quench and compression 😆 The reason we had this on the 349 was because it was the best match for the combination of parts. An RPM Performer was better suited for our 390 build. We had great dyno umbers with the 390 and RPM Performer. I'm quite positive we wouldn't have seen those results with the regular Performer that was used on the 349. Thanks for watching.

[@johncleggett9943]

You would think at Rogers Machine Shop to have cleaned up the jaggered edges on the exhaust outlet ports & match sizing to exhaust gasket. The corrode edges of the water galleries (both block & heads) could have been chamfered on the edges as well.

[@waynewalleye8458]

THE WHOLE ENGINE IS OUT OF BALANCE UNLESS YOU GRING EVERY PISTON TO THE SAME WEIGHT

[@MicsMotorworx]

We had that covered.

[@glenholmgren1218]

@@MicsMotorworx Not if, AFTER having the machine shop balance all the pistons, you start Ad-Hoc grinding mods on each listing skirt for "clearance" issues ... !!!! What am I missing here ...??? 🤷🏼‍♂️🤔😎

[@MicsMotorworx]

Pistons were re-weighed to within a tenth of a gram of each other. 👍😉

[@cmscms123456]

Did you figure for thermo expansion? as the engine heats up, the crank and pistons will swell/grow... Id have sent the whole kit back and let the manufacture sort out the problem, now the manufacture can void any responsibility

[@MoparMan-ff8fb]

a performer will restrict the power of a stroker. use an edelbrock air gap dual plan. see spacer plate I modified for my 318 on my channel ✌

[@MicsMotorworx]

Thanks for the input. We used that intake as it's what we had in the shelf. We went with a Performer RPM on the 390 we built for Project Fast Fish. We figured the future buyer of the 349 might change things around as they saw fit. Thanks for watching. 👍

[@dwaynehagle7445]

Aluminum Intakes require the Fel-Pro performance1215/1243, Edelbrock intake gaskets the hard blu fel pro's are for cast iron intakes.Ask Me how I know.

[@MicsMotorworx]

Sounds like an interesting story. 😁

[@44hawk28]

Torque sequence on the head should be more like 50, that's 75, then 95 or something or like that. It would be more critical if you will lose using aluminum heads. But you always do heads in a sequence of three steps. And if you have torque to yield you do three steps and then the torque to yield. The intake ports, but the exhaust ports were left Raw. At least it looks that way.

[@MicsMotorworx]

A lot of good information out there for these builds. Thanks for the feedback and information for those browsing the comments. We based the final torque number based on information from reliable sources for these heads. However, we opted for the first torque number in our 2 step sequence. Nothing wrong with three step sequence, either. Thanks for watching 👍

[@johncleggett9943]

Yes, the intake & exhaust ports could've had more work done, like clean up the edges plus match port sizing to the gaskets. Gas flow is important on the exhaust as the 2 middle ports are partly restricted. Makes sense to have 340 heads on as they have bigger valves.

[@jandaniel6499]

Anyone else notice him putting the gasket over a hole at 4:30?

[@MicsMotorworx]

Good eye. That one being covered by the gasket is designed to induce circulation. Thanks for watching. www.forabodiesonly.com/mopar/threads/340-water-passage-blocked-by-head-gasket.204887/

Amsoil number one oil for destruction of mopar engines .

[@MicsMotorworx]

How so?

[@bdmyers8896]

How long did that cam last with no break in oil or no coating on the cam , I would’ve not used that oil to break in my new engine. Exactly why I build my own engines.

[@MicsMotorworx]

The cam had been previously used in prior build. Same block. We appreciate the passion from the community and we all have are own ways of building. There's always something to taken from different perspectives. Thanks for watching. 👍

[@brettjohnson8009]

You can have the best break in oil made and still wipe a lobe .. or two ,the main thing with flat tappet cams these days is it is absolutely imperative that the face of the lifters be checked to make sure they are convex on the face and with the cam installed and before the intake goes on turn the engine over and make sure ALL the lifters spin in their bores ,it doesn't matter who ya got the lifters from either

[@HoosierRooster]

Leftover sediment from cleaning the block ?

[@MicsMotorworx]

Hey Mike. The channel and builds are more of a hobby for us. Pop and Jon work a small mechanic shop in Northern Florida for their regular gigs. When we first started the channel, they wanted to make it clear the builds and projects weren't going to become additional jobs. Myself, I teach a business class at a local middle school. I'll check with them and get their thoughts.

[@drdodge827]

Gasket OR rtv! Never both except at joints!

[@MicsMotorworx]

Hi Joe. Thanks for the comment. Were you referring to the timing cover or the little daps of rtv on the joints for the intake? For the timing cover, we've had a few leaks in the past. This is despite double checking torque and tightening sequence. Many disagree with Pop for doing this, but his way doesn't leak. For the intake, it is acceptable to use the little dollops of rtv on the gaskets for the joints as shown. Again, leak prevention. We also chose the cork gasket per instruction from Edelbrock. If a higher performing intake is used, such as one of the RPM series; then only RTV is recommended.

[@barneywarwick8745]

What year is the 318 your working on

[@MicsMotorworx]

Video 1 of the series shows the casting date as 10/25/71. I hope that helps 😉

[@Mr.mopar71]

J heads are a 1971 model year only.

[@MicsMotorworx]

Produced in 70 and 71. One year with 1.88 intake valves. The other with 2.02. We acquired them via a vehicle purchase.

[@jamesmackinlay4477]

I agree I have had at least 20 1970 340s back in the day all were x heads then the 1971 340s i had that about 3 of them I think had J heads on them.

[@BuzzLOLOL]

Was hoping it was a '67 fish...

@@MicsMotorworx look him up.

[@Mr.mopar71]

Too bad those aren't '71 J heads. Then you'd have the 2.02 1.60 valves.

[@MicsMotorworx]

Fair enough. We had 2.02 valves on our 390 which used 360 heads Interestingly, the port volume is quite large and the air flow is quite qood on the J Heads.

[@garryhatchett775]

Obvious question: why not just build a 360?

[@MicsMotorworx]

The concept was to use items we had around the shop. We had the block, crank, pistons, connecting roads, intake, heads and cam. The crank had already been turned to fit the 318 block. We're selling the motor to put money towards Project Fast Fish. 👍 Thanks for watching!

[@ufarkingicehole]

I appreciate being original but it seems it would make more sense to build a 360 or take a 360 , bore .040, use 318 crank, and use either 318 heads or 360 heads with flat top or dome pistons. I totally get why you did this but the same question was in my mind as well. Cool build

[@MicsMotorworx]

Thanks for watching and the ideas. It was all about the parts available around the garage. On top of that, this configuration was essentially what Pop wanted to put in the Barracuda in the middle to late 90's when it was originally gifted to me. Kinda neat he helped build it and had a chance to hear and see it run.

[@GrantOakes]

@@ufarkingicehole The mains journals on the 318 crank are smaller than the 360 block mains.

[@jamesseaman6919]

Not a good idea! Could cause oil leaks! I never use cork in the front!

[@MicsMotorworx]

There's definitely a lot of information out there from the community. The cool thing is, a builder can choose. Assuming this refers to the intake gasket, we went with it per the intake. We went went in another direction with a Performer RPM install on another build. Thanks for watching 👍
