61x case porting - Help Wanted

[Mouthfulloflake]

He wont show pics because Head makes his lively hood with these cases and that mod right?

wasnt that you UNclehulka?

so im wondering what good talking to Keith would do.. maybe just get soemgeneral ideas on the theory ..

I mated a 62t cyl and raider style pistons to a 61x case and it had a good hit. It was not ported but had about 170 comp and I thought it made good power. I am sure if the cyl were ported, bump to 185 comp, enhancer, an B pipe that thing would rip hard. Not a bad poor boy power plant :biggthumpup:

I have picked up on you guys and your suttle hints.

My engine in progress is 61x cases, 46mm carb, 62t cylinders, ported and bored to 83.

:Banane01:

:sneaky: your bore is a little small:sneaky:

 

[Matt_E]

are you leaking top secret info again?

With cheap cylinders, too. :sneaky:

I posted some pics in this thread too. I'll let you know what I think if I ever get the thing in the SJ. :banghead: I'm only use to a 6m6 right now, so I don't have a real motor to compare it to. Never got any comments on the porting.

my frankenstien 61x is appart right now. I think I'll try a little case porting when it goes back together. It's already a monster I hope this helps.

MFOL, I just noticed your carb is a little small too:sneaky:

i spy a new member to the x, online right now, that has said motor in a superjet, i may have recently sold him.... i clicked on his profile link.. and he's reading the barrel roll how-to thread... NICE.

that is awesome, fly high fly boy.:Banane01:

bore is small because those are the cheapest pistons and boreing deal I could find.

and I havent bought the carb yet, how large would you suggest?

:biggrin:

48

 

[Mouthfulloflake]

is that a stock carb or a modded 46?

I like the $75 46mm option, what does a 48mm cost?

[Mouthfulloflake]

ditto on the 48mm carb...

now you said "ported and bored" to 83... are those 62t 760 cylinders? they should be 84mm std bore size.. homes.

62t 701

mang.

:biggrin:

do the 62t 760s have teh higher port timing than the 62t 701s?

Both of the Raider ( I think Raider) 62t 701 cylinders I have have got 61x sleeves in them.

Id love to have a 760, but I assume from what ive read, they would have higher exhuast ports than these.

yes, the port timing is higher.

 

[Mouthfulloflake]

yes, the port timing is higher.

so then?

why would i want a 760 cylinder?

would that extra 20ccs of displacement be worth it given the higher EXH port?
