new 69 z/28 to restore

Cliff from Phoenix, AZ
REALTOR
just got a 69 Z and started the restore yesterday
trying to figure out codes and such.
wonder what engine to go with. I would like it street-able, 93 oct, no issues to run and handle AZ summers, but desirable to a fan of them.

Re: new 69 z/28 to restore

Welcome, Cliff! I noticed the rear sheel openings as well. Accroding to the trim tag, it was originally Ralley Green without vinyl top (79 79) with a black, standard interior (711) built the first week of May (05A). X33 would be for a Z/28 with the style trim group. Got any more pictures?

Experience...... It's what you get when you didn't get what you wanted.

Re: new 69 z/28 to restore

Welcome, Cliff. If you want an engine that is streetable, runs on 93 octane and will handle the AZ heat, look at swapping an LS engine and overdrive trans in. It ain't cheap, but the end result is worth it.

Of course, it won't be "original" for a Z28, but there are plenty of Z's running around without the original 302's in them.

Re: new 69 z/28 to restore

The quarters will be coming off. It was turned into a street racer, guessing late 80s early 90s - openings to accommodate 295-60-15's.
I have more pics than I know what to do with as I been tearing it down want to know how yo put it back together.

For engine and rest of car I want it to appear as a stock z/28 with 4 speed cowl system and air cleaner, etc, but I am concerned with the 302 high rev characteristics and do not want to run race fuel. With this info what is the best way to do an engine?

In that case, I'd suggest building a 383 and dress it as a stock 302

Welcome!

Check out Mike's thread
https://www.camaros.net/forums/showth...86787&page=108
he's added a lot of real Z stuff to his car, really nice job.
the last ten or so pages more pertinent to what you are asking about...a period LT1 350 built and dressed as a 69 DZ engine or do a 383

Rallye Green ROCKS , fixin to shoot my 68 Ragtop in it, last of the prep work FRI

Re: new 69 z/28 to restore

how would that affect the value of it?

My thought was to buy a 383 from summit and dress, but not sure if that would appeal to someone wanting a Z. The car can never be numbers matching so I am already down a bit in value. But is building a DZ block as a 302 but with lower compression and rollers, hydraulics etc. be more appealing.

just to clarify, do you already have a DZ-coded block (albeit non-matching #s) with the car?

Re: new 69 z/28 to restore

Welcome. Cliff. Nice car, Rally Green. I am in the middle of building mine as well. Looking forward to monitoring you progress. I am just about done getting all of my drive train finished. Lots of options for sure. Check my thread for motor details. It just came off the dyno.

Grandma, 69.5, Z/28 Finally Done! Well almost...

Building a low compression 302 in a true DZ block would be a waste, IMO- you'll spend a small fortune for the block, and end up with a fairly low-performance engine. Anyone who buys the car wanting a real 302 will want to have the have the whole engine be correct, so you're wasting money that you won't recoup.

No DZ block in hand. I found a few, one was a September build, the other an April date, my car May.

Re: new 69 z/28 to restore

I talked to an engine builder who is featured in Engine Builder quarterly who says he has gotten a 302 as high as 400 hp on 87 oct. Do not know but what he said and said its all in the pistons and cam choice to get it at 9:1. I have no way of knowing if its BS.

You can do a nice 355 or 383 roller motor dress it as a 302 and make an easy 400+ on pump gas. I'd run it up to 10.1 with alum heads (painted chevy orange if you want) and enjoy the car
