Me and my grandpa are putting together this exact engine even with the tri power on it but, the engine came from a 64 Bonneville that played in Savannah smiles
So glad that you preserved such a sweet running mill and allowed it to live on so that others can see what Detroit Iron was all about. But the hyd. cam with the solid lifters stumps me. But you obviously got it to work. Helped an old friend out with his 65 Goat who pooched a 10 bolt rear end with a 400 RAM air IV. sold him a 12 bolt out of a 68 Vista Cruiser. Problem solved. Love the detail and the exh. note.
Thank you sir for the Kudos :) We have been using solid lifters on Hydraulic rollers for awhile now. The reason we do this is because the aftermarket hydraulic lifters are hit or miss when it comes to noise and bleed off. We use solids and run the lash tight .004 to .006" and they run quieter and don't bleed off, it just works better for us.
I just bought a stock 62, stock Grand Prix. It’s the small 4 barrel motor but i5 only ha# about 15 pounds of oil pressure at idle. Judging b6 your motor I’m guessing that’s too low if gauge is correct?
Hi Richard, your oil pressure is fine. Pontiac's usually idle after hot around 7 to 15 pounds depending on weight of oil. Our engines idle a little higher because we blueprint all of our oil pumps and tighten up the clearances.
@@DonJohnstonDCIMotorsports Yea! Thanks so much for letting me know. Nothing like blowing a tidy sum and then noticing something you did not catch prior to writing the check. So far so good. I had to sell my first 62 GP the day before I got drafted into the Army 1965 and always wanted another.
Oh okay. I was inquiring because I just order a custom comp HR with 3316 and 3317 lobes on a 112 LSA for my 455 and was curious about idle character compared to this engine
No this is an engine we built for a customer. If you would like we can build you one like it. My email is dcimotorsports@sbcglobal.net if you would like to get a quote.
There is no need to dyno every engine we build. I have been building engines for 39 years and have dynoed my fair share, but just to get a dyno sheet for a daily driver or show car build is not needed. My clients do not all come to see how much HP they can get. Their biggest concern is having it built right for dependability. :)
Hey genius are you telling us you can't run a 10 :0 motor on pump gas ?? Well if it was you who talked him out of that compression ratio you threw away HP for no reason..

Cool, this is a sweet combo that runs well.
What a magnificent piece of American muscle history! DCI doing what it does best!
I love my 389.
sounds great, and honestly you cant beat the look of 3 carbs

Awesome. Just goddamn awesome!!! Seriously beautiful.

One little burp. Get on it.
Anyone know what type of oil to use for a 1965 GTO straight 6? I can't find my manuel.. thanx in Advance ❤😊
Our oil has changed so much since that engine was built and actually for the better. I would recommend you use Lucas Hot Rod 10 W 40 with high zinc.
Thank you
Not all 389 inch motors with 3 carbs were 348 HP. There was a 318 HP Version also.
There was , but it was used in the big cars not the GTO.

What Comp XR grind is it? Sounds good!
We have our cams custom ground to our spec's. We do however use the XR lobes.

What Brand and P/N engine paint ?
Duplicolor DE1610
Is this engine for sale ????? 3:53

They all respond like that with only a three-pound flexplate on the back . . .
Not all engines. We have had some real turds from other builders that dont :(
@@dcimotorsports1111 You're right. Shoulda' said "Anything halfway healthy etc etc", lol.

Put it on a Dino and show the results

@@DonJohnstonDCIMotorsports are the factory hp numbers about right?
