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!

I have a Cosworth vega with a 4.8 in it with a tremec tko 600 and it is absolutely terrifying in all the right ways on the street. Ran 10.70s but I had 275 radials on it and it was mini tubbed.

​@@damianlindsey6177If it has a 4.8 it's not really a Cosworth Vega without the Cosworth in it. Kinda like a Hemi Cuda with a 440 six Pac is not a Hemi Cuda anymore. Still sounds like a fun ride Vega"s were one of the best hot rod platforms from the 70's!

Back in the day Hurst made a V8 in a vega kit. Came with drag link. headers and motor mounts. I propbly did a dozen of them. I liked them, especially the Cosworths. I was a line mechanic at a chevy dealer in the 70`s, those little cars still did 100mph in third after putting 411`s in them, run right past 7000rpm. Just don`t over heat them

Very thorough with your builds! It's funny that the two main cams I was considering for my 327 build are cams you have used recently, this 30-30 and the SUM-1202 4/7 swap. I ended up deciding on a Herbert solid flat tappet 235/245 @050 109LSA 500 lift. That little 302 is going to rev to the moon with that 30-30 remake cam! FUN STUFF

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.

Had a company in the Dallas area that builds dirt track engines do the machine work ect to be able to turn it to 7500 . A set of heads off a g gas car. Solid lift roller cam ect ect . A fun car to drive for me on the street . The tach with a rev limiter was a good idea . As a missed gear saved my butt. The high rpm hp and not lay over at 5.5k was good also .That experience showed me the value of good cylinder heads . ..

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?).

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

In the early days, they bored a 283 to 4" and called them 301. AG

No torque on those 302 motors but they can scream like hell. Better have 4.10 or more gears with those engines. Have an original 30-30 cam that came out of my 265 in my 1955 Wagon!

I have a 69 DZ 302 block, would you be able to send me the specks on your motor. ?

Thanks for the question Don. The block was bored .030" and line honed. We used the original 1178 forged crankshaft. Scatt rods, 10.4:1 forged pistons. 1/16 ring package, file fit rings, The rotating assembly was balanced by Atchison Machine in London Ontario. The original heads were ported and flowed by Bill Little of Belmont auto in London Ontario, (260/190CFM @ .500" ). The cam is COMP solid lifter flat tappet 30-30 Nostalgia. 12-673-4. 108 IVC, 112LSA. lift .498/502", We also used the OEM "0" stamped rocker arms. The heads were machined for 7/16 rocker arm studs and guide plates. The correct dual plane aluminum intake manifold was also used. We also used a standard volume M55 oil pump with the OEM windage tray. Hope this helps. AG

What does a build like this cost nowadays?
@goldsgarage8236
@goldsgarage8236 Ай бұрын
That's a good question Marty and it depends on a number of factors. Do you have a good usable core? Block, heads etc. Stock rotating assembly or all aftermarket like SCAT or EAGLE? OEM or aftermarket heads, roller or flat tappet cam etc. A lot of things are optional or discretionary like line honing, decking and balancing. Can you do the assembly yourself. Typically a turnkey build, pan to intake is in the range of $6-$12K USD. Finding usable and correct numbers matching OEM parts can also add a large variable. Hope this helps. AG

I'm surprised you went with a steel shim gasket with aluminum heads. The rule is to only use steel shim with iron heads. Hope it works out.
@goldsgarage8236
@goldsgarage8236 Ай бұрын
Thanks for the comment Joe. These heads are the OEM cast iron heads, they are not aluminum. You are correct that the steel head gasket should not be used with aluminum heads. AG

@jims2286 Ай бұрын
7000 RPM is not necessary just ware out and over reving the engine.I would bet it will not make any more power at about 6400 to 6500 RPM
@goldsgarage8236
@goldsgarage8236 Ай бұрын
Thanks for your comment Jim. HP is a product of torque x RPM. A 302 does not have much torque, so it needs RPM to make power. Unfortunately we did not get to dyno this 302, but you are probably correct that max power will be about 6500RPM. 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?
