If your into just wining racers, the old addage "for straight line power, go cubic inches" holds true.
It doesn't when
you are paying the bills. The 200 out numbers the 250 5 to 1, and after a 17 pound bomb blast, its easier to get a 200 block than the 250. If your into winning races, the 250 will do the job admirably. If its a street and strip car, I'd go for the 200.
The stroker 347 kills the 302, amen.

If Ford Australia felt the 302 was a hand grenade, they'd never has stroked it, and increased the hp from 295 to 335 hp by the 347 crank. They just spent a bundle on all new parts so it could survive. Normally, a stroker
1) kills bearings,
2)blocks,
3)rods
4) pistons
5) smoothness
Simply because the of the laws of nature. If your getting a 13% boost in capacity, block loads, diff loads and transmission loads go up 13% too. All the time! So you spend extra on making sure it doesn't break! With every stroked engine, factory or aftermarket, there is extra periferal cost because and engine is an energy souce which needs to be contained in a car by other parts.
The little 200 with a turbo will give you all the power you could ever want.
However, the man is into the 250 turbo, and may Howard win every race!
