What is the differance between a 350 and a 355 motor?
Comments
The 355 is nothing but a 350 that has been bored .030" over
And we have a winner!! Mk 19 gets it right.
Same is true with a 461 and a 468, both are a 454 bored .030 and .060 over.
How did chevy come up with a 307?
Clue: It had nothing to do with reboreing.
Ok, here is a tuffer one!

Bingo! Not many people know that. I learned it back in high school helping a friend soup up his chevelle that had the 307.
Bore x stroke x # of cylenders = C.I.D.

Soup up a 307? Best way is to sell it and put in a 350. LOL
Now, the Chevy 302 DZ was another matter! Great engine.

Actually that little 307 did pretty darn good overall.
It's only down fall was off the line on a 1/4 mile run. And I really think that was due to the rearend gears (stock gears) and not the motor.
We never dynoed it so I can't tell you what power it was pushing. But it won it's share of street races.
one thing should be kept in mind when building an engine, theres no replacement for displacement [:D][:p]
At one time I'd agree with that, but with todays technolgy they sure do get a lot of hp out of small motors.

agreed, i have a 383ci that will put the hurt all over my other 454 vehicle [:D][8D]
Pontiac has 1 block for all 8 cylinder engines 265 up to 455. So when someone tells you they have a "big block" Pontiac, they are full of it.

I agree that the 307 was an under-appreciated motor. Obviously a 350 is more desireable because of the extra ponies that come with cubic inches. But the 307, because of the bore/stroke ratio, was superior to the later 305. One of my Novas still has a 307 with a 350TH tranny and it ain't all that bad, power-wise. (However, it will eventually get a 350.)[;)]
I notice you left out the 402 big block, shame on you [:D]

Another tidbit - Chevy has 2 basic blocks, small (30x, 327, 350, 400) and large (396, 427, 454).

Agree there, the 307 was better than the 305. Another great Chevy engine was the old 250 ci straight 6. Can't kill those things. My Mom has an old Malibu with that engine in it with over 300K miles on it and it still runs great and gets good gas mileage.

1957 Corvette, 283ci with 283hp
Rather have a 62'... first 327 w/ 327hp, first "StingRay" rear end, Last of the Quad exposed h/lights, last of the solid read ends....
Turned me off GM stuff for years.

Um Cutie,that would be 5
And on the topic of Chevy motors, anyone recall the first Detroit production engine to produce 1 HP per cubic inch?
Actually, the Packard made V-1650-7 from WW2 was 1650 Cubic Inches and developed 1,695 hp and was build in downtown Detroit.
Engines are my thang!!!

Before the legendary 327, the hot ticket was a 4X3 301, built from a 283. Was a revvin' SOB.

The 301 was a terrific modification, especially with Zora Arkus Duntov goodies in it and it would rev until it blew up, very unforgiving. However, if I remember correctly, you had to bore the 283 out significantly (.120), so you had some very thin water jackets.
If you can't feel the music; it's only pink noise!

and Sling B.... the 1962 Corvette has the same tail end as the 63 StingRay.... so it was the first StingRay rear end.....

I believe that the punched out 265 was the first "302". I imagine they lost a few blocks trying to get that to work in 55-56

traci, did you get your trk?,Loko [:D]
I did. I haven't taken any pictures yet. I've been busy with checking the truck out.
I think I did good on the deal. I have 3500 in it.
It's a 1985 Silverardo trim. It has AC,PS,PW,AT,CC.
It has a rebuilt 355 w/Elderbrock carb and intake,400 turbo w/B&M shift kit and torque convertor, and 203 tranfers case all from a 85 one ton.
It has a Corporate 14 bolt and Dana 44 axles from a 75 one ton.
I has new bumpers and mirrors and the body is a Geogria(sp?) body that is almost rust free. It's worst spot is the top. Everything is usable on the body. It's blue with a grey top and bottom. Bed is the best shape I've seen it's rust free and straight. Glass is good and most of the trim is good and usable. I has a new dual exhaust, but it looks like crap. think he did it himself, no biggy.
Almost everything works in the interior, it needs a new seat cover and a dash to be in great shape.
The tires are 35 Swampers, the lift is 4 years old. All it really needs is paint.
