In 1975, I built a DZ302 and used the GM '140' service cam. I ran it in my 74 Vega GT with 1 3/4" Hooker headers. The car ran 10.97 in the quarter mile on stock 7" wide tires. Without a doubt, it was the hardest car to drive on the street I've ever owned. With the Muncie 4spd when you attempted to leave the stop sign, you would either stall the engine or do a burnout without trying. Very unforgiving, but very fast!

You gotta really want that old school experience to go that route. I'm not sure I'd do that. There isn't any upside to it that I can see for a street car. 302 cu in Z/28s from 1967-69 are a Super Cool part of Chevy History but there is a reason why the 302 never made it into anything other than the Trans Am Camaro effort. It's a PEANUT sized V8 and with the introduction of the 327 Chevy had already moved well past this diplacement size in the years well before 1967. The DZ302 only exists because Trans Am limited size to 305 and under. Chevy wouldn't have built this engine if not for the limit on Displacement. Think of it this way. 265 in 1955, then 283, then 327 and then in 1967, the same year we saw the 302, a 350 was introduced. Torque moves street cars. Bigger displacement is the easiest way to find that torque and it'll make more Horse power without having to REV to the moon. As for a home built tribute 302 and if you want to make decent power you will have to find that power at high RPM levels. That brings up what makes the DZ302 so COOL. Chvey quite litterally threw every trick in the book at this enegine, within reason, at the time. Forged everything in the bottom end, 4 bolt block, and even free floating wrist pins. As lower ends go this was probably the raciest engine unleashed on the street in 1967. It had to be because Mark Donahue and other factory back racers were going to try any make a lot more HP than the street versions. 8,000RPM was gonna be hit at every shift point to make power. A very STOUT bottom end was the only way to avoid losing engines at every race track.

For sake of argument to make. Let's say I just want to make 450-500+HP. I can get there with a 302 or I can choose the super common 383-400 build we see so often these days. What I gotta do to get there is wildly different in terms of cost and how big the RPM will need to be for that 302. I can build a reasonably tame big inch SBC and get to those power levels at 6,000-6,500RPM pretty easily. With a 302 I'm gonna need some really good parts (far more expensive) because the little 302 will be full on racy. It's probably going need a 8,000RPM upper limit on RPM to make anything close to the same 500HP. Between cost and far lower torque numbers in the RPM range a street car will spend most of it's time driving in......this in a nutshell explains why you only see 283, 302 and even 327 engines in the cars where the engine is a numbers matching addition to the origiinality and value of the car. I just really cannot imagine any scenario other that a REAL '67-69 Z/28 that would lead me to build and install a 302 today.

The engine sounds great, Alan! You and your team should be proud of a job well done. I've built a few Ford Boss 302 engines but the smallest Chevy was a 327 with components that I incorporated. to mimic a Chevy DZ302. Both the Ford and the Chevy are happiest with low first-gear manual transmissions and low rear gears. The Ford will support a tighter, more aggressive cam and larger carburetor due to freer-flowing cylinder heads but is in desperate need of more cubic inches for the same reason. The "personalities" of both engines are remarkably similar. They will both rev to the moon and almost need to. I like the way you methodically document your work and related information and present it to the customer. I did it in a very similar manner back when I was doing builds for the general public.

That engine running brings back memories for sure. Funny thing about today vs the past. Engine Displacement in SBC builds are just so much BIGGER. In the end that trend to today is completely understandable. Cheap Horse Power and a lot more torque. One thing is lost though. That wild sounding idle. You can buy big lift long duration cams today too but they very rarely sound this good at idle. Engine displacement is a big part of it. The same cam profile in larger displacement engine always sounds tame vs the smaller engine. 302s and 327s have a reputation as engines that "Rev". This cam in a 400 build wouldn't sound anything close to so wild. In this 302 it's gonna be a fender shaker for sure. All of that comes down to how the same cam in the smaller displacement will move all the peak power numbers to a higher place on the curve. That ratty idle is a sure fire indication of how this one will drive. High RPM shift points are given based just on that sound alone.

Can you explain how the OEM's would have built all those flat tappet engines and never, I assume, used a 20 minute / 2000 RPM cam break-in procedure for the millions of engines they built. I have never heard anyone tackle this question with any engine build / engineering background. Either they were broken in before startup or they deemed it unimportant I bring this up because of the 30-30 mention in the tag line (Duntov 327 / 350?).

@goldsgarage8236Ай бұрын
Good question Gordon. I am sure the OEM's didn't break them in like we do now. I was in the FORD Dearborn plant in 1968. They were building Mustangs and Cougars. At the end of the production line, they strapped them to a chassis dyno, held their foot on the throttle for a few seconds, then drove them away. Today, we use a detailed, meticulous, time consuming and expensive process to ensure a successful break in. Some of it may not be necessary, but we are not taking any chances. One of the issues is the type of cams we are using. An OEM L48 350 for example has only about .400" valve lift, very soft acceleration ramps and valve springs with only 200lb force in the open position and 80lb closed. When you replace that with a performance cam with say .550" lift and valve springs with over 300lb springs in the open position, and more aggressive lobe ramps, the contact stress between the lifter and cam is much higher. i think the issue of quality control and metallurgy issues is an unknown. Maybe other viewers have a point of view on this question and can weigh in also. AG

Thanks James, 5.38 would work for sure. As to the second part of your comment, I wouldn't touch it with a 10' pole. AG

Here a reason you call a Z28 a zed 28? I never heard anyone pronounce Z as zed. Maybe your just being funny.😊 Why on god’s green earth would owner want a cam that big in a street car? It does not sound nor run like a stock Z28.

Seems like referring to Z as “Zed”, is common in machinist circles, usually in referring to the Z axis in machines. I’ve wondered what the roots of this reference are, as does it have some root in specificity, or is it simply a fashionable thing?

Thanks for your comment Gene. Zed is the correct pronunciation in Canada and most of the world. Zee is an American pronunciation. Thanks for watching and supporting my channel.AG
