i got some questions about strokers
1. ive heard then dont rev as fast, how much slower do the rev vs stock stroke?
2. also how much lower is the rev limit vs stock stroke?
3. how much do u gain in tq and where in the rpm range do u usually see it?
4. whats the power difference between big bore and stroker?

those are prolly questions that the op should know the answer to ask well in making a stroker decission

You can rev them as fast as we rev our cars. The only problem I have read about strokers on the 4.6 is that due to the fairly long stroke, the bottom of the piston comes out of the cylinder. Piston will go back up, but I have read something about how it wears down things faster and maybe uneven.

I got a Livernois stroker, it revs to 7000k rpm. However I didnt see any gains in hp or torque from the stock motor. Its identical to the stock motor numbers.

I wouldn't go with a stroker for the 4.6...most of the benefit is a larger bore to unshroud the valves......look at getting a ford racing 5.0 modular block...they are around 1900.00 for the block and you will gain cubes at the same time without the stroker stress on the wrist pins.....from what I have seen the biggest benefit is just unshrouding the valves a bit.....but the cubes always to help! I havn't decided yet if I want to just do the 5.0 block or just do a .30 in overbore and reuse my aluminum block....I would love to do the 5.0 block but the aluminum version is like 4000.00 for just the block....

the reason i ask is i bought a DSS 2v stroker motor and had a shop due the 4v setup on it. I've heard its power band is at the higher rpm's. i bought it for future setup. CHP said i would have nothing but problems because the strokers are not usually built for 4v motors. thats why i asked.
