Those little 302's sound insane when you eclipse 6K on the dial.
If you close up the lash just a touch and put a good set of hookers on it, loose the breather and dial in some timing you will be freaking amazed.

Well I can officially cross driving a first gen Z/28 with the original DZ 302 off my bucket list. This is the big boss mans car, I've been looking at it for 7 years, never had the opportunity to drive it. He's decided to sell it and said there would be something in it for me if I did it for him. Had some leaky rear wheel cyclinders which I replaced this morning, bled the brakes and put some fresh fuel in it. This is a fun car to drive!!! If anyone is looking for a decent driver 69 Z, this is a pretty good car. Not a show car, but a nice Z to take out and drive.

What's with all of the dust on the fan shroud??????? Dang slacking whipper snappers.

Growing up, my best friend's dad had one an original '69 Z/28 with the 302. So much fun!

Well I didn't hit 110 at 6,000 yet to blow it off...

Well lets get with it man. You have to hear that thing ring. They really do ring.

It was a common thing to go to the bone yard and dig out a decent 327.....then find a fair 283 and build what was eventually the DZ-302.
You could stroke up a 283 the same way but the specs/parts list has long since been dumped from my aging hard drive

Get a new Duntov 50-50 solid cam from chevy and put all of that under a set of fuelie heads (I know where 3 sets are to this day) and wow. You had a screaming little 301 as they were affectionately called. They would zing right up to and easy 6500 and could be pushed past that dependent on what springs were on the valves. The stock rockers would succumb to the madness so a spare 3 or 4 in the glove box was a good idea. Needle roller rockers were top fuel stuff back then. If we could afford a set of good springs we had to pin the rocker studs in the heads. I learned to blueprint an oil pump during these mad science experiments.
These worked really well with a stupid high rear gear and 3 peddles in a Nova or similar light car.
Think daily driver.....

Great times.

I have to to get some better tires.
It keeps breaking loose just before the 1/8th and just gets worse when it shifts.

 

[ChristianPatriot]

0 - 100 in 10.5 but the quarter in 13.0 @ 97

 

[Brad69]

I had to lift because I was going sideways around 110!

 

[churchmouse]

OK......now I know where 4 sets are.....

He mentions blowing the tires off about the 1/8th. That will kill the overall.

 

[thunderchicken]

Get a good set of drag radials and that should help it not break loose @ 1/8th. What kind of car is it?

Make that 6 sets if you add my 2

The only draw back to those heads is the closed chamber design. The later open chamber designs actually flow better but the valves are generally 1.94 intakes and not the 2.02 of the fuelie head.
They are conducive to higher Compression ratio's.

Not heard much about the truck lately. Did you get all the issues worked out...???

 

[thunderchicken]

Dodge

Even their name tells you to stay away

Crap. I need to remember to grab a piston to bring into work tomorrow... Engineering a Poncho. And so it begins...
