Are there any disadvantages of a 383 vs a 350?
More power,none that I have found.
I haven't seen a high milage 383 before, usually because people I know who build motors whale the bejesus outta them. Just food for thought.
The only disadvantages of a 383 would be that the engine will be a little less prone to Hi-RPM operation than a 350. But we are talking the extreme RPM ranges (7000+) before this even starts to be an issue.
For a street car there are really no draw backs to the 383 other than cost
I agree Lowend. They are not an RPM motor. It also depends on what do put into it. I am hoping to get a long life out of mine. The bigest issue it it pull RPMS go quick it is hard not to over tach.
Yes there are.
They burn more fuel, make more power, and tend to lead to more tickets- and often the dreaded racing disease. They stress the car's body more (back to the more power thing) and they're addictive.
Ummm, I think that's about it.
My thoughts exactly! As far as costing more, if you are buying a rotating assembly anyway, there shouldn't be much at all besides block clearancing and new damper and flexplate. The kits are about the same from a 350-434 for good stuff.
If you don't wail on them too hard...you can use stock GM parts and build it pretty cheap. All I did was take a stock cast 400 crank and have the mains turned down 200 thou and bought a set of pistons with the pins located closer to the top to work with the stock 350 rods, used the 400 flexplate and balancer. The rest is totally stock parts. If plan on beating on it, you may want to spend more for some better parts that will take the beating.
Like you've always heard...it takes money to go fast, or a fortune to go a little faster.
So...how fast do you want to go?
forgot one...really hard on tires. even big wide ones LOL
is a 400sb a lot different than a 383?
