Laz thats a lot of time playing on a flow bench .That Porting gets old after awhile

Good luck

After some bugs that needed worked out with this engine and our boat, we thought we were finally ready to post how really happy we were with this motor. Not as fast as everyone had predicted - 70.4 GPS in our Baja 272. BUT, exactly one month to the day after Laz's warranty ran out, we had a lifter fail which wiped out the cam. Not sure yet what other damage there is. Only 29.1 hours on the motor.

How much hp was your motor on the dyno that got you to 70.6 and what prop were you turning. What brand lifters failed,parts do break once in a while ,too bad it happened after only 29.1 hours? I had a rocker nut crack allowing lifters to get loose and bend a pushrod and screwed up a set of lifters in my 540 last year after about 20 hours BUT luckily nothing else got damaged. My 540 previuosly to my current engine made 630 hp/700 ft lbs on the dyno with cmi headers and my 272 ran mid 70's before turning the boost up more and going to a 12 rib blower drive,Smitty

You said you wiped out a cam after a lifter had failed. Sounds like you had the engined dyno agian at 624hp once you replaced the cam after the lifter wiped it out. (???) I am only asking because of the title of the thread..."This week's Mesa Project 670hp"

I lost a lifter in the middle of the summer as well...but I was blessed enough that it didn't do any damage to the cam or any further damage than just the lifters themselves. Otherwise it could have been much worse! I was using the high grade Comp Cams lifters, but replaced them with the Morel lifters.

4 years ago my 540 made 630 hp/697 ft lbs of tq on the dyno with cmi headers,not dyno headers. I was extremely dissapointed with what motor made (it wasn't on laz mesa's dyno or anything to do with him) but I have the same exact boat-a baja 272. The boat ran mid 70's before touching the motor or tune after it came off the dyno. This motor had a supercharger and made almost 100 ft lbs of tq more than eagle 272's,it went 4 mph faster than his,his speed although dissapointing is very realistic for the power he is making,Smitty
