How to Build a Chevrolet 454 Big Block Part 4: Replace the Camshaft and Clean!

[@fireguy7004]

HEY RYAN YOU SAVED ME!!!!!!!!!!!!!!!!!!!!!!!!! Long story but I took my 454 to shop A in late feb. 2 to 3 weeks they said. 3 months later they still had not finished it so I pulled it and took to shop B. shop B found that the crank mains had not been ground, just polished, the valve seats had been ground wrong. when I cleaned the block I found the rear cam bearing had two scratches, shop A had installed them. couple of weeks ago I went to install the cam and it wont go into the rear bearing. So I took it to shop B and he replaced two of the brand new bearings I get it back and this is where you saved me! I checked the bearing orientation and the rear bearing was not aligned with the oil passage! I have built engines before but never thought to check this! So thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Watching your app had me sucessfully put in a new trimming chain kit.454 chevy sounds great Gracias.

[@2carpros]

Nice work!

Well WD 40 definitely repels water but it does not keep your iron from rusting long-term so it has its application, here's a good test spray cast iron with WD-40 and then try JB blaster put your hands on the surface of the as well as the JV blaster you will see which one will rust because moisture got into the weaker oil.

Very informative.got low pressure in my 454 88 chevy that I'll. be tackling

[@DereksVideoLife2011]

thanks so much for this series. Awesome knowledge sharing. Much appreciated.

[@2carpros]

Glad you enjoyed it!

I’m more concerned with the abrasive cutting tool remnants than micro metal. That abrasive grit will cause failure even if no metal is present. I use a lot of mineral spirits and engine brushes to run the the oil galleries to get any stuck dried on debris completely out. You have to mechanically agitate every internal surface to be sure it’s all out. Nice series so far. 👍

[@MrMorbo420]

Thanks for these videos. I have been using them for my 454 build with ARF 265s. I had a cam ground to make it a low end grunter. It's in my 36' RV. The stock 454 is about 200-235HP. I thin the new build will do a little better job pulling a 20Klb RV up a mountain. Well, at least be capable of. Not doing any bottom end work except oil pump. The block only has 44k on it. Cam got swapped today! assembly begins!

[@2carpros]

Nice work! That is going to be amazing! Thanks for watching!

[@bender49ers]

How did it turn out?

[@MrMorbo420]

@bender49ers amazing! it pulls 22klb over the continental divide (look up Loveland pass) 4 times. overheating is an issue on long pulls. I am adding a jeep xj radiator to it this week along with a large oil cooler. it has the resonator in the exhaust only. so pretty much a straight pipe. it sounds amazing. a streetrod engine along with all the sounds in am rv is kinda awesome

[@MrMorbo420]

@@bender49ers oh, it actually ended up being a double build. I lost oil flow but had over 150psi. tore it down and had bearing soup. so I quickly sourced a new block (rvs have 454s) and did a full rebuild. it was fun swapping the engines. but the basic swap took about 4 hours.

[@bender49ers]

@MrMorbo420 that's great to hear. I just picked up a 454 rv block for 500 bucks hopefully I can get it into my old suburban soon.

[@MrItsthething]

Good video. Make sure you blow out and spray WD40 in your oil passages as well since water could easily pool in there and take a long time to evaporate.

[@anthonygiannotti9968]

very cool man thanks for posting this series cant wait for part 5!

[@2carpros]

Thank you so much for watching!

[@viruschill6736]

Wait late to the party. Is the engine in a car? Do you have video of it running? I would love to hear it. I am building a 454 now and trying to pick out my cam. TYVM for this video it is GOLDEN.

Thanks so much for watching! I can't remember the title, I just got it off of KZbin's Audio Library for creators.

[@TubeInspire]

Thanks fonthr videos I am falling each one to start my build question? dowels and cam bearings hardware should be provided by the shop bore price or is that something we purchase and take to shop?

[@2carpros]

I always have the machine shop install those for me and I double check the fit when I get it back. Thanks for watching!

[@TubeInspire]

@@2carpros👍 will do thanks again and blessings 🙏

[@philipgavin6962]

Should have washed it before core plugs an oil gallery plugs went in. Thanks for your time though.

[@2carpros]

How would I have done that if the machine shop installed the plugs? Thanks for watching!

[@orlanmedina3693]

I wash it with gasoline. And diesel to avoid corrosion

[@saschazegerman]

When sending the engine to the machine shop, what do you 'order'? Check the engine, measure the engine? Thanks for infos on that

[@2carpros]

Basically you ask "What's this engine going to clean up at? Can you magnaflux it? Is it a good block?" Then they test it and see how big the bore needs to be to clean up at. Thanks for watching!

[@ericstruckmeyer6770]

wd40 is the wrong thing to use as it has silicone in it (iron is porous) . Primer/Paint doesn't adhere well on a silicone coated surface. 1st-wash with pressure washer/ scrub brush. Use compressor and high pressure air nozzle to blow off all water quickly. 2nd- use Acetone to wipe down all surfaces of the block (acetone stops rust flash and is an excellent de- greaser used prior to painting metal surfaces). 3rd- tape and paper off all surfaces of the block that you do not wish to be painted and Spray Paint engine block with self/metal etching engine block primer. (Wait 20-30 minutes at 65-70 degrees)( Remember different paints dry at different rates). 4th- When primer is "very tacky" (test with gloved finger on taped area), Spray Paint engine block with manufacturers correct year /date code engine block color (or custom color). In your case Chevrolet orange. This protects the outside of the block from rust. There are also specialty paints for the inside of the block that also promote better oil drain back to the pan. 6th-After your paint has "set" and is dry to the touch, carefully remove painters tape/paper, chase all bolt hole threads, and coat threads / and all other non-painted surfaces with a light coating of oil to protect those un -painted surfaces from rusting.

[@2carpros]

I used carb spray and mineral spirits to clean the block before painting. We have been running the big block for awhile now and have experienced no issues with the enamel. That is good stuff. Thanks for watching!

[@KaoticFdr1]

WD40 does not contain silicone

[@prevost8686]

Wrong. WD40 is the correct thing to use and it doesn’t contain silicone.

[@jamescostello5525]

Did the machine shop put the bearings in

[@2carpros]

The cam bearings yes. Thanks for watching!

[@devonparish5678]

Hey how long can I leave it wrapped with the cam lubricated

[@firearmconvention946]

What was the cost of the machine shop work? I'm just curious so I can get a idea

[@2carpros]

That was like 1200-1600 depending on area. Thanks for watching!

[@TubeInspire]

Im stuck in my cam selection can you help? I have a 454 cast#12550313 the engine is confusing me as a new builder its like a gen5/gen6 combo i believe i can go hydraulic roller cam but a flatt tappet came out off it. Thanks

How much does the machine shop charge for something like that ( engine block)?

600 I believe. Thanks for watching!

@@2carpros no prob you got good content

[@elguerrodelnorte2345]

What is interesting. Upon you installing the piston. The piston rod connects to the cam shaft and is torqued down. I noticed the space that the rod is connected to on the cam shaft what stops the rod from sliding back and forth while the cam shaft turns?

[@jamescostello5525]

Does the block absolutely have to go to the machine shop

Been using it as such for many many years. Works great. If you prefer to use something else then use that. Thanks for watching!

YEESS. It’s done every single day in every professional machine shop on the planet. They Then quickly spray them down with WD40 and blow them off with compressed air.

Yea I wash mine with soap and water. Been doing longer than this guy is old. Heck of a cam. Link in the description still works. I'm doing a 92 tbi 454 right now.
