Building a 350 Chevy for STREET/STRIP with Vintage Chevrolet Angle Plug Heads!

Your attention to detail and your ability to explain the what and why excellent. I enjoy that you are keeping the old school technology alive. I am sure that you are like a mentor for many many people and it show's that you really enjoy what you do.

[@MVPisME383]

You got to have that kind of attention to detail to build engines successful. I just built my first engine for the public and it is nerve wrecking and I know I double and triple checked everything

[@goldsgarage8236]

Thanks for the kind words Walter. I call that psychic income, i can't buy anything with it but it sure feels good.AG

[@toddbrown2236]

The photos displayed in the video were a nice touch and very helpful. I even paused the video when the pictures came up so that I could study them more thoroughly. Video is great but I also think it's helpful to sometimes have a still photo that can be studied so I commend you on taking this approach. I'm looking forward to hearing the engine run and very much looking forward to dyno day. Thanks for the video. Happy New Year Allan to you and your whole crew. Cheers!

[@goldsgarage8236]

Thanks Todd, good to hear you liked the still photo method, we will do more of that in the future.AG

[@tomrayborn6558]

I enjoy all your videos , keep up. the good work .

[@goldsgarage8236]

Thanks Tom for the encouragement, glad you enjoy them. AG

I hope those plain stainless steel head gaskets don’t cause you any problems. I would have coated both sides of those head gaskets with your copper spray or Holymr spray. 👍🇦🇺

[@mrho4speed]

Thanks for another good video = looking forward to the dyno run and the comparisons!!!!!!

[@goldsgarage8236]

You bet! Thanks for watching.

[@StuartBlake-iz6rf]

Alan, nice job, great project. Happy New Year.

[@goldsgarage8236]

Thanks Stuart, and happy new year to you as well.AG

[@DeanStewart-t4v]

Will be watching to hear it run, nice build.

[@goldsgarage8236]

Thanks Dean.AG

[@ericuncapher9922]

I have put a lot of engines together and I still find you interesting.. thanks for another great video!!

[@goldsgarage8236]

Nice compliment Eric, thanks for watching and contributing to my channel. AG

[@dondotterer24]

Had the pretty much the same cam. It was Cam Dymactics. In a 327 with Rhoads lifters. 10.1 461 heads. Mild bowl work with a Wieand 8004 dual plane and a 800 Quadrajet. Hei distributor. Both had some work. It ran awesome and smooth and made some good low end torque.

[@goldsgarage8236]

Thanks for the input, great combo! Thanks Don AG

[@kevink8481]

I saw a video on Jim's Machine shop where he adjusted valve lash with a dial indicator instead of a feeler guage. Fast, easy and obviously very accurate

[@goldsgarage8236]

thanks Kevin, I am a subscriber, I will check it out. AG

[@kevink8481]

@goldsgarage8236 I am as well

[@65chevy]

Looking forward to the dyno video. Keep up the great work!

[@goldsgarage8236]

Thanks Chevy. AG

[@Hillbillygarage1215]

Another great video, thank you AG. Happy New Year!

[@goldsgarage8236]

Thanks Ronnie, Happy New Year to you as well.AG

[@greggc8088]

I learned the teflon sealant on the head bolt trick the hard way years ago. Good insurance unless you want to keep Bar's stop leak in it all the time.

[@goldsgarage8236]

Thanks Gregg. It's a pretty important step.AG

[@gregleenyit]

Excellent Alan that's going to be a sweet running engine. Happy New Year.

[@goldsgarage8236]

Happy New Year Greg.AG

[@DennisL-n6i]

Great engine going to watch the dyno 😊

[@goldsgarage8236]

thanks Dennis. AG

[@GregMargraff]

I'm glad to see the progress Mr. Allan! Ban't wait dor the dyno results. I'm guessing490 hp @ 6k and 510 ft lbs @ 4k/ Hope your leg is healed up, Happy new tear!

[@goldsgarage8236]

thanks Greg, all good now! AG

[@davidcallahan5157]

Used that same cam in buddy old 350 1970 Chevy pick up truck with stick, after many years we put new set of vortec heads felt like we gained 50 horsepower that cam would pull to 6500 with ease.

[@goldsgarage8236]

Good info, thanks David.AG

[@dinoa9608]

When milling heads, when does the intake manifold and head angles cause sealing issues requiring custom angle milling of the intake manifold? Machine shop took .003 off the stock surface. I assume this amount will not cause issues? Thanks for all your insight.

[@goldsgarage8236]

Thanks for the question Dino. .003" will not cause any issues with fitment. You are good to go. AG

[@alalwin8249]

Good solid engine building information. I stop by often for the latest info on engine building. The engineering question I have is, on automotive engines why are intake valves always larger than exhaust valves? They are both critical to the flow of gasses,. I think I know why, but I'd like to hear a scientific rationale for the difference. Thanks

[@goldsgarage8236]

Thanks for the question Al. The intake valve and port are larger because the intake charge (fuel/air mixture) is drawn into the cylinder by a vacuum caused by the piston descending on the intake stroke. Exhaust gases are forced out of the cylinder under pressure caused by the piston moving up on the exhaust stroke. The pressure of the exhaust stroke is higher than the vacuum of the intake stroke, thus smaller port and valve. Hope this helps.AG

[@stevewalters6853]

Great video! With the size of those exhaust ports what size headers are going to be needed to not restrict the port opening they’ve created?

[@markmcmullen1371]

👍👍👍

[@goldsgarage8236]

Thanks Mark.AG

[@jamescereda2628]

Second owner of a 1965 chevelle in 1977. The original owner changed the 327 to a 1966 corvette create 327. Witch is a 350hp. With an aluminum intake, holley 600 cfm .I rebuilt it and lowered the 11 to one to 9 to one. 30 over cylinders. Put in a stock GM 300hp cam. Deck was milled 5 thousand .Don't remember gasket thickness! What's your guess of the HP it makes now? Thanks! And Happy New Year

[@goldsgarage8236]

Happy New Year! With that setup, you are probably around 300 hp. James, believe it or not this is the AI response, and based on the info I have it is pretty close. 300-320HP maybe. AG

[@goldsgarage8236]

Thanks Steelcity. AG

[@CEFOED]

I don't see anything on valve adjustment for SBC

[@goldsgarage8236]

Thanks for the comment. I do have previous videos on this subject, and i will cover it again in the future. AG

[@CEFOED]

Which video or videos is the valve adjusting session video in ? Thanks

[@joe-hp4nk]

What was his reason for using a even duration and lift cam? Over 90% of cams installed are split event cams.

[@leosun8469]

Usually, the split pattern cams are to make up for a lack of cylinder head flow, specifically the ratio of intake to exhaust flow. Maybe he felt that those ported 292 cylinder heads would flow enough (general rule of thumb is at least 75% exhaust to intake flow) so that it wouldn’t matter?… That cam is an old Comp grind, but it works and sounds fantastic- I’ve used it myself in a 10.0:1 355 ci sbc build and it worked great.👍

[@goldsgarage8236]

thanks Joe, the other reason is that this cam was already installed in the engine and it was in good condition. AG
