I find all this very interesting , as I have 4 - 49 cube motors, including a 65 short shaft, a 70 powerhead on a hustler short shaft, a 70 long shaft w/power trim and a 19 75 -75 horse Hustler short shaft , that had been raced in Sport E .
so fred i have seen these cast in liners you have spoken about, both my 814cc blocks have them,... so what 49 cuber can i get to run those mcdaniels pistons in?? :eek::cool:
p.s. this is the best thread and site ever! i spend all day on here at work! :eek::D
it's not easy to find a press in liner Mod50 case, if ya did you most likely need sleeves,???? i have not found any:(,
any way, castin works,:eek::cool:

ahhh well i am in business then, no havent found any without castin liners..
so to make this work with the mod50 pistons what clearances will i need etc? as you mentioned the 25hr life span will come into play...:eek:
im tipping it more then the .008?
the piston +.008 be good, when She gets to temp She'll be that .004 -.0045 Mr. NERSTROM was lookin for.;)
She's guna get hot on the exhaust bridges, best not to make them toothpick thin, be best to back them out of the bore.:eek:
i'll get a fresh shot of the press in Mod50 case:eek::cool:
Can anybody still get pistons from Phill? The Last i heard was he was out.
Hey Fred,
Why you say to lose the Stacks?
hey there fred.. so my new 56cuber im building has finger ports however they are .500 wide :eek: so im thinking i dont want to make the holes in the piston that big.. or do i :confused: im thinking it dont matter if they arent the same width.. :rolleyes:
will post a thread on drilling my fingerports in my wiseco's then we can all share info :eek::cool:
the stacks will speed up the air more, the low pressure at the Ventori will get too high and the mix will get too fat, slows her down.
don't think Phill has any bullets left, thinkin Sea-Way gots one ring at 3.030:eek::cool:
.500 is big, you can Dee port the holes in the piston, think i gots a shot of what that looks like. what size were holes in the old piston, did any crack?
Dee Ported:eek::cool:

the piston ports were simalar size to the ones in the block none of them cracked., im doing the rest tonight, but just wanting to know whats good or bad.. im thinking they dont have to be the same, i might have a look at how we'd go making the ports like a D.. we've done one piston already and it looks good, only thing is i dont want to take too much meat out of the piston near the gudgeon.. but i may have to as at the moment the hole is quiet small..:eek:
ill try and get some photos
I have a set of 3 new, McDaniels pistons if ya need them, 3.030
I believe you are close to the estimate Sam.
If you are going to run a batch of Weisco pistons in Mod 50 version, and don't want to oder such a large quantity, why not simply turn them ? Weisco's did not have the dome as the original Mod 50 did. So making your own could be a very easy job. Pro category does this a lot. I imagine a local machine shop could turn and mill pistons to match the Mod 50 exactly for a price, and you would not need to buy 100 sets.
not seein why i would turn a Stinger piston down, then thare is the wirst pin hole:eek:
at Wiseco for 3 grand, it takes most of the day to set up, then they will run 12 pistons, then you need to spend more money:eek::cool:
Seems as there might be enough interest in my pistons to have some more made. If so, I will have to have orders for at least 1/2(50) before I order. My order will consist of .020s, .030s, and .040s over standard bore(3.000). The quantities of each will be established upon the interest in each size. I talked to Wiseco about a month age and with my quote, the pistons will still be $100.00 ea. w/ rings,wrist pins, and clips. Have some rods and plenty of brgs. to convert to Mod-50 size(large) Brgs. and rods run $100.00 for each set. Rod $80/brg.$20. Let me know if interested. E-mail or call home-843-650-0400 or cell 843-446-7767. Phil
********** Dave or anyone else in setting clearence on your bore, PLEASE check the taper on my pistons as well as the Mod-50. You will find a greater taper than the stock/fishing. I like .004 Phil
i'll take a set of .040 overs, got your note, look for it in the mail, thinkin friday.:cool:
hears that 49 case with press in liners:eek:

The pressed sleeve die cast blocks were made by putting a special aluminum blank in the die, in place of the stock iron sleeves. After casting, the aluminum blank was carefully machined out leaving the intake and exhaust port passages. You could not tell a pressed sleeve block from a Tradewinds block without looking inside. These motors made a lot more power than the stock Mod 50 but Jack Leek would'nt let us use them since we had customers racing Tradewinds motors. The first one was raced by Jeff Brown at St. Louis, this was when we raced 15 minute heats. Jeff won by a big margin and started the OMC domination of Mod 50.
i needs sleeves:eek::eek::cool: gots to get me some:cool::cool::eek:

hey Deanster you out thare:cool:
i'm tuned in fred
you de-lurked me:eek:
the 56er looks good....keep the pics coming!
hey 850, what triggers you got under that fly wheel, what is that flywheel from.:cool:
I see you are using the oval port 56. Have you tested one of these against the bridged port?
Fred: that fly wheels just a standard 70 and then one day it met the lathe :eek:
Hey there Popa Sam, i had a bridgeport on it, it blew up.. and this was a spare block i had as the bridgeport needs sleeves i decided to just go with the one
got some sleeves for this, guna resurrect it.:eek::eek::cool:

Question for everyone...
Would a 56ci benefit from being rotated anti clockwise like the m31 with the exhaust on the other side... Spinning backwards should move the thrust to the other side yes?
If a left hand gear box could be fitted to it would it show an increase?
it would make about 10 more hp. LA sleeve got them sleeves, not sure who you talked to:eek:, but i ordered 3 of them:eek::cool:

May I ask why you put some other clamp bracket ( NOT OMC ?) on the MODUH ? HUH ?
is it narrower that the 3 cylinder omc bracket ?
