Whats the differences between these as in performance? I know the stroker has more torque and the all bore has more HP as I was told by MTI, but that really wasnt helpful.

All Bore baby..

why?

I knew you would answer sometime Vince <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> lol

Well.. From what I have been told the All bore is cheaper and you get more tq.. Someone correct me if I am wrong..

Stroker will handle more nitrous though. Interesting topic....I'm interested as well.

I was corrected.. Strokers make more tq and all bores make more peak horsepower. Strokers are more reliable according to my source.. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

All bores have all the issues related with sleeving a block, but love to be revved.

In comparison they love to be reveved. The stroker limits piston speed and they have a smaller bore which will effect airflow especailly up high.

My opinion is that the All Bore is better over all only if the sleaves are done right.

Taking any issues of sleeving out of the equation. An all-bore will dominate a stroker in every way of similar displacement.

All bore has the bennefit of unshrouding the valves, for better flow.

Less side wall and recipricating loads

Quick revver

Great option for forced induction.

With a stroker you get "dead spots" and top, and bottom dead center while the crank is moving, relative to an all bore.

Quickin

Better idle quality with a more aggressive cam, with the stroker. And more TQ is better than more HP, IMO.

They should not be compared directly. TQ all by itself is meaningless and does no work without movement (RPM), which = HP.

Bottom line is bore over stroke, when displacement is similar, the bored motor will dominate in a drag race.

I tend to think like this:

A4
Lot's of low end torque fun to drive around town a 382 stroker would be the most fun.

M6
Fun to drive and rev a 382 Big Bore would be the most fun.

Easier to live with and least likely to have problems with: 382 stroker

Or what about just get one of those "dime a dozen" C5R blocks and have a reliable all bore motor?

Huh?
Huh?

Yes, a stroker will probably make more torque, but all bore uses less piston speed which long term is better. Like I said before, them hill billys, (NASCAR) use big bore small stroke. They get 750 hp out of a 356 ci engine. That is 2.1 HP per CI. That my fine furry friends is phonominal!!!!!!! A stock LS1 is probably right at 1.1 HP per CI. Cons with a big bore is it takes the flame front longer to go across the piston. If you want that big block feel, go with a stroker. If you like hangin em high, big bore will do it. But what do I know,(built a 525 HP RB Mopar at the tender age of 20 years not even using the best parts). <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />

FaSS Blac,
A NASCAR motor is also a pile of junk after a race and they idle horrible, not a good comparison to the street cars we got goin on.
Same with a 950 HP CART motor, there amazing but totally useless on the street. Not to mention methane gas.

The engine doesn't know whether it has more bore or stroke. The heads and the intake ports are what makes power. They only "see" pressure drop. There is no difference between the two according to the heads except that the motor with more bore can "breathe" better due to either larger valves and ports or the same but less shrouded identical ports so the "bore" motor will ultimately make more power. As some of you other guys noted however the bore AND stroke motor will make even more than the others.
