One issue can be valve to cyl wall clearance , if using big valve heads.Any issues using a 383 based stroker build? Especially since there are more donors available?
Buddy of mine ran a 496 383 with RPMs for years,, 9.90/10 ohs.

Here is my silly answer...............Before I had my own dyno I ran my 451 stroker on another dyno. It made 787 HP @ 7,200 rpm and the dyno operator/owner said, "It rev's like a small block Chevy." Later we ran our 500"/440 on that same dyno where it made 848 HP @ 7,200 rpm and the Dyno operator/owner said, "It rev's like a small block Chevy!"
We can all draw our own conclusions I guess.
I've wondered about the "it revs faster" comment before.
I would think, all other things being equal, if 2 engines were tried in the same car, if one revs faster it must make more power.
Like I said earlier looking for header clearance, spark plug maintenance ease, and I don't need 650 to 800 H.P. I've had it. Just looking to build a 500 H.P motor for a stock factory appearing 70 Roadrunner, and I think a 451 is a good candidate to make that easily on pump gas, and the stealth heads sound like a good option for the stock look.
Thanks, that made me laugh!
I figured you would have some real world experience with that I appreciate it!
What would you anticipate from
a stroked 451 B ( 4.375) vs a .050 (4.370) over 440 (450ci), both have 3.75 stroke and 6.76 rod ,CH being the difference everything else being equal.
Anything to gain ?
Thanks IQ!
Here is your answer. I could not have stated it any better.The lighter Bobweight may Rev faster in Neutral ?
But
when pulling against a 'load' then 500hp/500ft lbs is 500hp/500 ft lbs.....
all I'm saying is I think we're confusing the effect of less parasitic power losses of the lighter bobweight ? but whatever 'power' is whatever 'power'.
Once you make 500/500 with a 400 based build at the flywheel.... then it is still the same 500/500 with a 440 based build at the flywheel..... no matter the 'load' applied to either.
I don't know....my 440/505" would rev up through the range like a motorcycle, even with my 3.73 gears.. I had to shift earlier because I wasn't making it happen in time to stay off the rev limiter.This may be a silly question, but it's based on rumor, not experience, but has anyone ever compared a B build to and RB- CI being similar ,stroked/bored, similar/same valve train/induction and looked at how fast the rpm builds?
Simply put, many say that the stroked B build rpm faster than does an RB and therefore prefered.
Just curious if there is any truth to it.
Thanks

The "when pulling against a 'load' then 500hp/500ft lbs is 500hp/500 ft lbs..... " is only true if the load and rate of change are the same.
.
That's why this place is awesome, so many knowledgable people willing to share! Thanks againHere is your answer. I could not have stated it any better.
