Pretty sure 112.

I'm going to have to take a look at the final pull and see if that dip was still in it. I'm not 100% sure that dip really exists, maybe some quark with the way the dyno loads when the pull starts? I'll have to take a closer look at the detailed dyno output and see if anything stands out. The first sweeps were way too fast @ 800-1000 rpm/sec. He slowed it down for the later pulls, but still not slow enough. Even though the dyno had a knob that seemed to adjust the sweep rate he said it wasn't that easy? The further along the builds got the less faith I had in his abilities. Ultimately I'm not really satisfied with his work.

should have used 108,,would have made way more powwa.:D

who's abilty are you talking about?

The engine builder is who I'm not really satisfied with for several reasons.

As far as making more power, I think what I got from these heads is decent. I have no opinion on the 112 lsa. Someone else can spend a few days on a dyno swapping cams, checking for reversion, idle quality, powerbands, peaks etc. and post the results. I think my new philosophy is going to be, if I don't see it on a dyno it doesn't exist. If I change any component on an engine to make more power I'm automatically adding $600 and a day on a dyno into the equation. Edit- actually I don't think I'm really interested in making changes or being involved with a build again based on my past experience. I think I'll just write a check to Innovation Marine and let an engine show up and if that doesn't work I'll leave the sport. As far as hands on engine work goes I have yet to meet anyone in this industry that I'd ever go back to and I don't have unlimited funds to find a new builder to spend thousands of dollars with every year or two .

see the :D,,I was making a funny.I use cams in the 112 range all the time,,unless I'm building a really big cube motor.

Sorry, that's ok. Whether kidding or not that's still my thoughts on the whole thing. But it does get tiring hearing what people think should have been done after the fact.

Me too lol and that 5 minute 4200 run we did lol

We can agree there no doubt, if I listened o a select few I would have been in a better place but most came up after I was done shopping, oh well ..hoping this is my last round, as far as trusting? Well the best can have issues so I guess I am ok with learning and building mine...

.

I am currently cam shopping and have ruled MK out after reading all this. One thing that came to mind is it may be helpful if you have any info on time frames for this? It may help others that purchased from him one way or another.:)

I dont have personal exprrience w .680 lift cams and 240 duration but i will say in my opinion IF a guy is running any sftermarket hesds that keep flowing past .650 lift to use somethingw only .550 lift would seem to leave hp on the table. Even mercruiser runs .600 lift on 500 efis w iron heads, a customer bought a turn key blower motor from big als toy shop that we installed and rigged in a jet boat this summer and it had a "old school" low lift cam like what your talking sbout and thr horespower numbers were absolutely dismal!
