If you are offering a service, best to do it by PM, else it will look like advertising, which we kinda frown upon.

"DZ" coded blocks (69 year) I thought were all large journal.

Way back (69 or so)we used a crate 302 chev for our junior fuel dragster. These were emensly popular back then for JF. They were very cheap for what you got. You could not build as nice of short block as what you got from GM. They would take 90% nitro all day unless you leaned it too much. haha

As a side, my bro in law bought a new 68 302 Z-28 with 4.10 and 4 spd. He thought it was king @#$ untill I raced him with my 67 396 SS 4spd. I probably could have helped him out by towing him instead. haha. The Z was a bit better on the corners though. Kinda relative anyway as Red Lines were not very good on corners on any car.

Gotta admit that the Z did sound good wound up....like a boat with too small of prop.

..Just had to toss my 2 cents in on the 302 chevy engine. In 1963, I built a small block chevy using a 327 block and a 283 crank. Using the light flywheel clutch and pressure plate, only a 5.25/4.80 roller cam, a 2.20 Borg Warner 4 speed and 5.38 rear end gears. I was able to take my '56 vette to 9500 RPMs, and run the 1/4 in the 12's. After 47 years I still have the car--now with a 350 and the old style Rochester FI. The car now has 297,000 miles. My friend and partner was the first to break 300 MPH in the 1/4. bunky@pwhome.com

Hot Rod Mag (or was it Super Chevy?) did a 302 buildup within the last year or so. I checked my file just now but couldn't find it. Sorry. It was called "Chevy 302: Recipe for Power" or something like that. Gotta say though it was pretty spendy. Hogg's tip on the 4.3 V8 crank sounds great though--if I remember right the article used a small journal block with a forged 283 crank, which could be hard to find. I couldn't find it with a VERY short web search of those sites, but if you dig deeper you may have some luck.

Fivepoint, back in 62 I had a 57 Chev 210 with a 283 hp 283 and 2.2 T10 with 5.38 .. We ran 105-106 but only 14 flat. This was before the Casler and M&H slicks. We just had Atlas Bucrons....street tires of the day. 6800 was about it due to stock valve springs.

Sure would like to have one of those FI today. We sold ours for $125 in 64. Dunb dumb.

...kinda fun to relive the old days. For some reason, we actually called the motor a 301 CID--probably something about the decimals. I was running at Green Valley in the Dallas Ft Worth area. I had taken everything off the Vette that would unbolt and got the car down to about 1800 lbs. I lifted up the front end about 3 inches and had what were called street slicks. I could get a little air on take off, but nothing like today's rods.
...I have some photos of then and now if anyone is interested. My partner, who ran a D gas Willys later won both the national points championship in NHRA Funny Cars and Top Fuel--the only driver to ever do that.Budweiser has been his sponsor for over 30 years...They wouldn't even give me a spark plug. bunky@pwhome.com

I have a 41 Willys strteetrod undergoing some updates. It will be back together early spring. 350 +.030 400 hp. great streetrod.

All had 5.7 inch rods I beleive.

All these engines were produced for homologation in the Trans-am series to compete against the 302 Ford Boss engines that dominated at the time.

All 283 cranks are forged




so you can use any one to create your engine, just make sure you get the right size journal block to suit. You can get spacers to fit a small journal crank into a big journal block or have the crank ground to fit, I don't recommend either. Why you would want to destroke a perfectly good 350 or 327 is beyond me? Are you trying to get into a specific class of racing?

They don't sell 302 crate motors because everyone wants the bigger cubes. Here's a site with a good breakdown of Chevy engines.

not true.
67 283 cranks were not forged...
