Tristin Posted April 12, 2014 Report Share Posted April 12, 2014 Is this a build thread? A sighting? Cool picture bro. Quote Link to comment
ggzilla Posted April 12, 2014 Report Share Posted April 12, 2014 Cool! Yenko was a dealership and they sold every type of Chevy. My sister had a Chevelle 250 it was fun and stylish. Quote Link to comment
datzenmike Posted April 12, 2014 Report Share Posted April 12, 2014 But mostly known for 427 motor swapped Novas, Chevells and Camaros. That looks like a 307 Powerglide. Quote Link to comment
Lonestar Posted April 12, 2014 Report Share Posted April 12, 2014 Yenko made a 307 Chevelle????? Wow!! 307? I swear the numbers read 402 on that decal. That is a badass car! More oics, feed us! 1 Quote Link to comment
datzenmike Posted April 12, 2014 Report Share Posted April 12, 2014 402? then it's really a stock 396 0.030" over then? They called them 396s but was really a 402. That's just paint or a decal. The '69s SS came with 396s in them so Yenko would have replaced with something not readily available like the 427 or the next year 454. At the least it would have the 396 and SS emblems on it and surely the SS hood. Sorry, it looks like the base model 307. Besides... the title says Tribute not that it's a real Yenko.

ggzilla Posted April 12, 2014 Report Share Posted April 12, 2014 The 402 was a factory Chevy offering. They overbored the 396 at the factory. On the chevelle the 402 was badged 396 as mike said. It didn't come out until 1970, and the photo is a 1969 chevelle. Quote Link to comment
mrmark Posted April 13, 2014 Report Share Posted April 13, 2014 My father had a 69 Yenko Deuce in the mid 70's. He didn't have it long but I bet he wishes he never sold it!! It wasn't a big block car either, it was a Corvette sourced LT1 350. Quote Link to comment

I didn't know Chevy even made a 307. Not busting ya Mike, I just didn't know where the 307 came from. Quote Link to comment
datzenmike Posted April 13, 2014 Report Share Posted April 13, 2014 I think the 307 was made from an even earlier 283 with a 327 crank? The 283 was the son of the 265. The first gen stove bolt. Quote Link to comment
Bory Posted April 14, 2014 Author Report Share Posted April 14, 2014 It's cool to let you guys kinda go off on your ideas of what this might be. It is a 307 car. When I started the build in 2003, I for sure was not gonna do just another SS clone. Haven't we seen to many SSakes!? So what I came up with was a 72 truck motor 4 bolt 402 stamped BB. it is considered a 396. So 1 point for one of you. It has a B&M built 350. And a heavily built 10 bolt with toms axles. The entire chassis and all bolt ones are powder coated. All hotchkis suspension, Billet specialties serpentine belt system. Wheels are 18" 10 rear and 18" 8 front on BF goodies. It's just a bad ass driver that looks like something Don Yenko would built today. Quote Link to comment

Yes, 307 is basically a stroked 283. It's a 327 crankshaft with a 283 bore block. Which would have really honked from the factory if set up to do so, but it was not. For no other reason than "because" I did build one once with decent flowing heads, raised the compression and put a smallish cam in it. It ran strong, really strong actually. But, in reality, kind of a waste of time, because you can put together a 350 for the same money, with less effort and kill it. Many guys I sand drag with build 302s (not ford, Chevy) which is a 283 stroke crank with a 327 bore. They will run a 7.13 rear gear ratio and turn them past 10k. One guy runs headers that are all 8 tubes in one big collector. Thing sounds like a die grinder when he's getting ready to launch. Quote Link to comment
datzenmike Posted April 18, 2014 Report Share Posted April 18, 2014 302s were the original Z28 motor wasn't it. Quote Link to comment
smoke Posted April 18, 2014 Report Share Posted April 18, 2014 Yeah, a DZ302. It was a hot little bugger. Made small due to cube requirements in trans am if I remember correctly. Quote Link to comment
ggzilla Posted April 18, 2014 Report Share Posted April 18, 2014 Stock 302 revved to the unheard of speed of 6000 rpm. Except many didn't because the wrong springs were fitted at the factory. That same year the Datsun 510 engine revved to 7000 rpm. Quote Link to comment
