7 pedal

[TEXAS20225]

just a fyi the sleeve's in a 200 efi ff block are the same# a 225 pmax in the advance sleeve catalog difference is rod slots and giant champer on pmax porting James perry has made several AZZ kicking pmax blocks for me out of 200 ff blocks along with lots of folk on the forum that perform better then the stock pmax

And that's exactly what I have at the moment

When James did my block he said the same set up was 3 or4 mph faster than stock PM, tested on bullet bass boat, but I think that's with 4/5 pedal, I have good comp #s to make up for sum bottom end loss. I spin cupped 28 chopper out of hole spinnin it to moon , gonna leave 4 pedal in it for now and mite just send sum ex cages to Chris to open up with a custom reed and try that route ,

The ff blocks I got have 260 port. Sleaves were removed hand ported 20 years ago Slots done and said were stronger than stock 260 on the lake these blocks have 7 petal fronts and need 32 c.c heads

I bet it will b a runner , but 1 thing James Perry showed me was 260 sleeve has very small intake port (I believe), which cant b matched with a 200 sleeve cause the intakes r so much bigger on everything else ,with the 2.4 200 being the biggest, you can port match but cant intake unless u use 260 sleeves, I mite still have the pic. I'll look,
Notice difference, that's 1 thing that makes 260 run so gud
Unless I just mixed up wit what he said , he was teaching me lots of things in short time and was tryin like hell soak everything in ,lol

JAMES IS IN A LEAGUE OF HIS OWN and all by his self . i used jim Ruck for years he was good but james p is way ahead of jim r, i fact i used them both at the same time because one machine shop could not keep up with what i was selling i find James work is so much better especially on port work he is the best ive seen ever, plus he does not buy assembly line sleeves he makes his on and they are precise and exact duplicates

James is the man. 2.5, talk to James about the 7 petal, he does tons of bass boats that tournament fish and get his opinion, being he knows how your ph is set up. From reading a lot of stuff, I get the feeling he and Rex on the same page with the 4 petal on bass boats. Sure you can probably get some more mph out of a 7, which is the whole reason I’m trying it and it’s just a big experiment for me to see how it effects low end, and if some mods I’ve been doing to improve bottom end will help overcome any loss of bottom end the 7 may have and in return make one bad little combo. But, I will assure you, the 4 petal is sitting on the stand on standby just in case it don’t work. If it works, then that motor will be opened up and tweaked some more for the next experiment to try improve on this one, it’s how ya learn what works and what don’t. Some of things that had worked for me to improve low end torque was by accident shooting for more top end and some of it is 180 degrees from what is supposed to work.

Yep I love hearing these thangs, I so need call him and ask bout 7 on my set up , funny thing u talk bout James and rex, both like mopar also lol, James does know his **** tho. , wish ole rex get back on and throw a hint or 2 also,

[Merc 2.5]

O by the way. I busted 80 today ,like the 70s wasnt even there, tach only goes 6. Buried it QUICK , I'll have check hr meter to c hiw hi it went but last time said 7200. , proud this little motor as its idling behind me

[FORBESAUTO]

Lol, wish he was still in it too! I’m telling ya what he would say, I’ve spent enough time with him and picked his brain enough to know. But I can also tell ya what works for one don’t work for another, there is soooo many variables on way things can be done on these motors, and everything has to compliment the other. That’s why you read so many disagreements from how some mods works or don’t work, it’s not that one side is complete idiots, but that there is more to the story on why you see different opinions. Look at my exhaust chest for instance, most would say that joker would kill bottom end, but it compliments the rest of my engine and actually improved it to the point that that particular chest has made more torque than all of the disignes I’ve tried, including the stock 200 and the norm lake cut 260 ported motor I started out with.

Ok some I'm sumwhere round 72-7300 according to hr meter , tach only goes 6 buried that quite quick, should I just have sum cup to tops added to this prop or just cleaned up, I think I could use just a hair more bow lift. I think I'm gonna add 2in to jackplate and wanna get sumthin done to this prop while it's getting straightened out from today, what yall think? Any recommendations

[FORBESAUTO]

Some cup and more jack plate will both give it more bow lift. How much trim do you need to give it to achieve max speed? And what type lower you got(coned, low water pick up etc)?. You want to try and find a set up where runs top speed with engine as near as level as possible. Be careful with trying to get a lot of bow lift, I found that works good up to around 77 on my set up, after that needed to put nose down to go faster. When my set up is dialed in, I trim it past level to get her up and runnin, and around 77-78 start bumping back down to to get top speed. Generally if ya trimming too much, either it’s propped too big or engine needs to be raised(as long as water pressure allows) If it slows down by raising, talk to your prop guy to see if he can tweak the prop to do what you want or time to try some different props.

I have lwp,plenty pressure I can spin a 28 over 7k so I wouldnt think I'm propped to big, it runs that prop great and real gud hole shot. The set up is close , I think 2in spacer would b exactly what I need, I'd love to try 4 blade over hub prop
