hey i want to put a new engine in my 72 bug and im wondering what size i should get? i just want the long block and want to spend around a grand, maby even more.... i want something that doesnt feel underpowerd and fairly fast?? tell me whats out there guys?? and the web addresses to the engine builder or whatever... i was thinking a 1835 or a 1915 but i dont know??? thanx guys!!!

There's so many factors to consider that displacement alone is not the only criterium, but since that's what you asked I'll try to keep my answer relevant. I think it's better to build a smaller engine right than to have to cut corners to get a bigger one together; with no budget for headwork, carburetion, and a serious exhaust system I'd go with the 1775. It'll be OK with limited carb & exhaust but still respond to improvements down the road. A 1915 can be built for about the same money but will be stifled more by inadequate breathing, and it will not last as long. 1835 is a non-starter, they went out of style decades ago unless you're only after a grenade that's fun for the short time it'll last. It's all about cylinderwall thickness and how long they'll maintain a ring seal; 92s are inadequate, 94s are marginal, and 90.5s are nearly the same as stock - none can survive overheating without sustaining irreparable damage though.
...opinions will vary (wildly!)

depends if you want to spend money on some good dual carbs and a decent exhaust. also if you want to run heater boxes forget anything bigger then a 1776. if you spend the money on dual carbs like some 40IDF's or Dells and a bigger exhaust then i would build either the 1914 or 1776. put a smaller cam like a 110 or 120 that will give you a decent ride without head work and then save some extra money later, get some head work and you'll have a pretty quick ride.
