Dz 302

It seems to be gone? you hope it will get re-listed?? You didnt save the original ad or at least save the phone # so you could contact the seller after posting this thread?

Bullshit!

 

Don't want to rain on anyones parade here, but DZ motors were only in 69, the 67/68 302's were MO, not DZ. The stock motors had 11:1 compression and if you wanted to run these on the street you needed to buy Sunoco/Phillips76 or someother high octane fuel.........mine was pretty much stock except being blue printed and balanced and with the close ratio 4spd and 4:56 gears it was one hell of ride back in the 80's!!!!!!
I know, I had one and did a ground up restoration..............the car in now in Scandinavia.
Here are a couple of pictures.............and I did have Protect-O-Plate to prove it. It even came with the road racing aircleaner which attached to cowl, and the original Hooker headers....................both of these items came from the factory in the trunk and were put on at the dealer.
If anyone wants to know all there is to know about the early Z28's all you need to do is get a copy of Jerry MacNeish's book titled the "Definitive 1967/1969 Camaro Z28 Fact Book".
One last thing.............the person who said the Z's had underdrive pulleys was kind of right, they did have an underdrive pulley on the "alternator" only.

IMHO

 

Working for A Mopar dealer in 1968 I use to love to see the Z28's on the street. Someone always told them how fast they were and I enjoyed hearing them rev the hell out of them when I passed them with my 5800 R.P.M. Road chicken.

 

Really why not just build an early 302/301, 327 block and 283 crank, EVERY PART to a '67 302 is standard GM stuff exept pistons and mabey?? intake

I'm putting one with a cross ram in a '64 el camino, as soon as I get the door from being 1/2" off my steering wheel(T-bone victim)

 

I had the same idea of throwing one together, I have a few 283 cranks and a standard small journal 327 block. I also just picked up an m21 muncie 2 weeks ago. What would you guys recommend for a rear end gear for this screamer? I will be going into a 63 nova 2 dr hardtop. I was planning to run around a 26" tall tire in back, thanks

I did save everything and it did just get re-listed. Here ya go...

 

A buddy of mine has one in a 30 Model A coupe out of a z-28.It is backed up with a built turbo 350 with manual valve body and 3500 stall and revs like a son-of-a- bitch.Really makes that little A fun.

 

For those interested in a 302, Chris Craft offered the exact same engine as a 310 FLV in their 69-70 20-21 foot run abouts. Mostly in front of a Volvo Penta 250 out drive. Also the same for the 350-350hp used in Vetts during the same period. Problem is I didn't remember looking the engine number of ones I have worked on.
Same block/heads/cam/pistons/ valve covers/intake carb ETC. Keep a look out for one.

 

Sounds like a lot of fun!

 

The engine of choice for midwest dirt supers like my avatar, back in the 70's.

 

When I get around to it, I'll post a couple of pics of my 302 air cleaner lid... Both sides even! The real ones have the AC Delco ink stamp on the underside...... For years GM was selling the intake manifold at the parts counter... I wonder if they still have those brand new??? And what other heavy-duty parts they still have in the parts books??? Anyone here work at a GM parts counter?? Please let us know!!! You could also build a 302 using GEN II parts like an L99 cast iron 3.00" stroke crank and LT1 5.7L (350 ci) block both from the early '90's.

 

Here's the rarest of all the DZ 302s - only three engines built with the Weslake 32V heads and only ten pairs of heads cast - of which four were destroyed in testing....

 

I would cut one or both of my testicles off for that.

 

Where's the pictures??

 

i would have to agree with the others, and say grab it

i think they make a true hot rod motor.

i used to run a 69 z with one, till we stuck a rod through the block at 10g's or so. wound up stickin a 427 in the car, and only got a couple 10ths improvement.

those 302 at full revs have a sound all their own, but partrs do fly

weasel


thats one sweet mill

Maybe just my left nut....

 

I have one I bought new in the crate and never used it other than in a show car, has less than 10-20 miles on it. It is for sale on the classifieds here. I bought it in around 1970 and I am not a BS artist, what I say is absolute. They are one of Chevrolet's best Small Blocks for high revs. Oh, I had mine balanced the day I bought it out of the crate. Good luck with your choice and if that one is there reasonable you should secure it today with a deposit. Greg,CGM.

 

I bought a 68 in 1975 for $500 with the motor in the trunk missing the intake & carb, even had the teak steering wheel which is worth more then that now. I made it into an NHRA D/stocker that ran a best time of 11.72 @ 116.95. Sold it in that trim in 1977 for $2000. It was a S Florida bondo bucket but thats still one of my dumbest moves selling it. It was an early 68 with the small journal crank

 

A-HA!

I have a '95 LT1 block, and have been wanting to build a high-winding motor, but up until now, I didn't think it was feasible. I loooove the sound of a 302 wound up tight.

 

Thanks guys Ima gonna buy her if shes there when I get back. Would be pretty sweet in a Model A coupe backed by a four speed and a quickchange rear.

 

Those cranks can be found in Caprice taxi cabs with the L99 4300 motor from '93-'94 Or other Caprices. Not sure if those dates are correct!! You need to look into the manufacturing dates for the L99 motor. I'd say NYC erea are the most plentiful.... That's just a wild guess.

 

Yep! That's one of about 3 engines that were built as prototypes.... Those heads are a canted valve design instead of the inline wedge design. The crossram intake is also different compared to the '68-'69 manifold.

 

Yeah! That's what I said to!!

 

Hmm. Cast iron.
Anyone want to hazard a guess on how durable that crank would be if the motor got wound up to 8-9000 rpm occasionally in a 3500lb car?

Ideally, I'd like to have the rev range of a 302, and the gas mileage and durability of a EFI LT1. I know there's a combo out there- It's just a matter of how much I want to spend, which isn't a lot.

\Sorry to hijack the thread.. Carry on.

 

About as strong as a 383 cast crank turning 6k or so because the rod doesnt have to travel as far each revolution, hence why 283's and 302's are screamers

 

I'd like to build a "detuned" street version of a chevy 302... With a pair of T/F Twisted Wedge heads and a shorter duration camshaft. A set of flat top pistons should get me around 9.6:1 cr. A T-5 trans with a 3.35 first gear ratio and 3.73's out back should get a 3200 lb car haulin' from the git go.

 

Well, I would just like to say the 302 is my new favorite engine.

 

It's just too bad that GM didn't take the time to play with that combination of crank stroke and bore for future use like Ford did with the (O/T) 225 horse EFI HO 5.0L/302 c.i motor.. Those stock Fox bodied Stangs ran 14.2's (give or take) all day long with a 5-speed manual trans and 3.08 gears out back with a good driver..... Like yours truely!
