I'm running a 350 60 thou over 2 bolt 010 block in a HQ Monaro. Built it about 30 years ago, still running strong. Recently I ditched the holley and installed a quadrajet. This was the bigger 800cfm model. Its on a Victor Jnr manifold so I made a 13mm plastic adaptor and did a little blending in the manifold inlet. A bit of tuning and doing some research, these are not a easy carb to tune, but its now magic! It starts easy, good highway economy, and better power and response than the holley. No flat spot, I can nail it from any load or RPM and it just goes. On the dyno we got just over 400hp. Highly recommend the q-jet if you have the time to fiddle with it.
Also affectionately known as a quadrajunk
@@tims001 only by those who dont know how to tune a carbi. It is a thinking mans carb, but the results are good.
Awesome! 👍
ebay all my stainless nuts and bolts on line ... but thks for the offer :)
Very cool engine color!👍
Hey joe what are your thoughts on torque plate honing? See you haven’t done any on your last two rebuilds thanks
I do belive they are necessary in getting an accurate cylinder finish for high end builds. But what im doing here is cheapo home job. Seems to work fine at my power level.
@@Joedennett69 awesome thanks
Jeez you had a tall camera man in this video
Lol
There are good head options for these
What is the part number and brand of your flat-top piston please!?
They were a hypatec brand 0.040 over piston. Part number, no idea i bought them over a year ago.
How much hp and trq please ✌️
I dont know. I ran 12.9 on the quarter mile with it.
Good work Joe its looking good mate should be a strong motor once done cheers.
Lookin forward to turning tires.
I like your color choice, what is that some sort of charcoal grey?
Called titanium grey aparantly.

I like it, it looks really good. 👍
Are you self taught engine rebuilder.? Looks like you know what ya doing ya 5.0l runs mint. Good on ya mate.
Been doing it since i was 13 years old. Don't know why but have always had an interest in engines. Yes self taught.
zero valve lash won,t be good mate you probbley need 5 or 10 thou so once warm you will have less than zero valve hanging open
Was just doing what I did before. But looking into it. I will increase my lash. Herd people say that the clearance gets larger when warm and I have heard people say it gets smaller too. But if people set lash that would infer the lash getting smaller so I will put some more in it. Cheers
When hot will expanded close up the lash same as fitted the gudgeon pins in the rods
@@jasonbrack4738 Yes I have figured will sort it out tomorrow before the first fire.
If it's hydraulic cam 0 lash plus around half a turn on the nut soild cam needs around at least 5 thou cheers mate love the build 👌 👍
@@jasonbrack4738 If you have anti-pump up lifters with a hydraulic cam you want zero lash, if you add half a turn after that it won't run. Solids you would want to start around 0.024 thou.
