Congrats ,thats some impressive #'s!!!

Way to go Rob. Engines look awesome. Boat should run awesome too! My guess is mid 90's no problem. Maybe even faster

They look great! What did you build?

pair of 572 cubic inchers , dynoes were also fully dressed .hoped for a little more. but very happy with phaffracing engines , and joe from baca marine . there now the same entity . no more nascar builders . well i guess phaff built the dodge engines, but everybody makes one mistake .

My buddy had a pair of Phaff 900's in his boat. Never a problem with them. Those are good numbers for a N/A 572 in full marine trim.

100 would make me giggle

only thing i dont think they had at dyno session was the headers . just decided at the last minut to spend more frikken money . they looked too nice to have ugly exaust on them LOLthanks guys

100 might be a stretch, but maybe! My engines made similar power, my non stepped 38 is right around 88-90 right now.

You've really outdone yourself on that boat. Cant wait to see it on the water screamin....

Wow! Nice job!

Nice !!!!!!!!!!!!!!! Hope they run as good as that little nascar motor. Had it checked out at the end of the season. The shop I took it to thought it was a new engine. It's back in waiting for spring.
