Turbo 250 or 350

It is my understanding that a 350 has almost the same external dimensions as the Glide, uses 15-17 more HP just to turn the transmission than a Glide and a 350 weighs a little bit more than a glide(maybe 15-20 pounds) and you cannot use a 350 with an engine that revs over like 7000 rpm( they want to self destruct). BUT you do get that extra gear in there!!!
Now a Metric 200 has the lite weight of a Glide, you can spin the engine well over 7000 RPM like a glide , it takes about the same amount of HP to turn the trans as a Glide AND you get the benefit of the extra gear. Its weak point is UNLESS it is really beefed up it will self destruct on its own at low RPM , in a heavy vehicle, in normal everyday street use that's why GM stopped using them.
Unless you are looking to extract the last thousandth out of your car--you do not either want the hassle of the maintainence or have the ability to do trans work you might be better to go with a 350 til you hit that plateau in your level of performance where you feel you could use the extra gear that both transmissions over---Comp 387
