A number of builds I can think of did well with B1s and less cubes. B1Wes made 940 hp with 540 cubes, partially ported B1 originals on race gas. In the Fastest car list, B1 Ken went 8.178 at 2430 lbs, stock block B1 511 cubes, single four. Others in that list show decent power for B1 motors.

That would be 666.25 c.i. I think you meant 4.495 bore.

Don, want to donate those "garbage" B1s? Might make my tank run a little better.
Seriously though, what makes you think they're garbage? I bet Tommy or Al could fix them up to make some power.
Thats just what I've heard from guys that build motors that make power.. No matter how strong the short block can be.. that the B1's are the limiting factor
But it sounds like these heads are very capable of 1000 hp and personally speaking, I wouldnt call that weak

How many of you are there out there and what kind of numbers does it have? I've been told my Originals are garbage and they will never make power.. So was just wondering what its real life capabilities are for a motor this size..
What type of engine are you building, street or race.

Well Don.. There are waaaaay too many so called 1000+ hp motors out there running the same ET as mine, and at less weight. My CAR has run 8.78 @ 154.9 here in Phoenix. Approx. 2800-3200 DA. 540" B1 Originals.. P/G, 1150 Holley, 4:30's, 14 x 32's 1.24 60 ft. glide.. Really set up for S/ST. Wallace put me @ 890 hp uncorrected and 950ish corrected.. (That's what dynos are... Corrected) Never did the Dyno thing, but the real numbers at the track are the ONLY thing that matters..  Put the motor in the car and start tuning..  BTW.. My B1 originals flowed 416 @ .850 on 3 different benches.. AND my Barracuda weighs 3000#.. Chris..

The term "garbage" heads had a context. Might be good idea to recall the conversation. And compared to other stuff at this shop the term "scrap" might be a better term  There is more Aussie Pro Stock stuff lying around than one can shake a stick at, not to mention all the record setting Comp and SS stuff. Man are Mopar guys sensitive. The more I try the more I am convinced of it.

Depends on your porting and induction (single 4, tunnel ram, etc.).
I think it is safe to say if your goal is 1000 hp or less, they are suitable.

I dont think sensitivity is appropriate here, as its all a learning curve to me..
But when you're talking to a respected engine builder about the B1-O heads and the word "garbage" flows out of his mouth.. and then is followed up with "dont waste the money on a set of Ti valves".. Well, thats gonna get your attention and is in need of follow-up..
In my opinion, these heads are better than most and not as good as others, but they are serviceable considering the money I dont have to throw at it right now..
But the purpose of this thread was to gauge how efficient my motor is compared to others that are out there..

Well we both know what yours made and what the issues were that are robbing it of at LEAST 30hp. AS for titanium valves. The engine was built to be a reliable low RPM deal. Titanium valves are not needed it makes peak power at 6900 and IMO that money could be better spent to address some other issues that need to be addressed.
Just trying to ad context here. Even with the issues you are almost at 1.7, not "just" 1.6. Once the big issue is repaired it will be over 1.7 even if it picks up only 6 HP it will be there.

Since the cat is pretty much out of the bag... Here is a picture of a partial dyno sheet from earlier this week.. The only thing worth mentioning is the vacuum pump we have on the motor, didnt work well and could not create enough vacuum to make power.. Rick Watters suggested a new vacuum pump could be worth another 40 HP... But it is.. what it is.. enjoy

I would really like to make more power than that but the limits the customer put on this build, no vacume pump, 7000 RPM peak HP goal and so on I'll be happy with 900+HP 
Don't tell him I said this 
My mistake, the second one this year
