I am in the process of building a spare long block. My current setup has the brodix bp bb2 extra cnc 355cc heads. I contacted Brodix yesterday and they said that i should upgrade to the bp bb3 extra cnc 366cc head. Has anybody else tried the bb3 heads?

I rebuilt a pair of merc dry sump 900's a few years ago and put those on with a bigger cam and it picked up about 10 mph in a 40 Skater.

I use them on my 598 and it picked up 5 mph. Didnt lose any acceleration. With your blower set up I bet they would be amazing.

It took a while but I finally got 2 sets of BB-3 xtra 380 cnc . Have not finished the project but they are going on 598 's with big whipples .

BB3Xo 351cc runner on a 598 hp was 930hp 6700rpm na fuel injected 10to1comp. Now i have the head hunter heads on the same 598 hp is 960 at 6700 rpm dry sump engines with vacume on the crank case. head part# 383mc head hunter think they made my valve angle 52deg. these motors push my 41 apache on a good day 110.7 no step on my boat.

Any new updates on these Brodix heads ? this is a 4 yr old thread . Anyone have recent success stories for the BB3x REC or Ovals?

BB3's made 150hp more than BB2's On n/a 598. Same cam. Same dyno...

Stay away from square port heads. Try to stay under 360cc runner it will have better usable power take my word for it. I had bb2+ went to BB3XO 351 Than to HH383MC The BB3XO where bad aSs.
Made 930hp with the BB351XO

What kind of power did they make?

884hp @6000 9.98:1 compression. I forget the Torque but it made 700ft lbs @ 2800 rpm.
