701 or 760

[JayB704]

This is probably already on here somewhere but I'll ask anyway, which would be a better engine a for superjet build the 701 or 760? If you were starting from scratch with just a hull?:bigeyes:

You will find that the majority of people recommend the 61x 701 cylinder with the 62t cases. A good build would consist of the following...


61x cylinder
62t cases
ADA girdled head
factory B pipe
650 flywheel/stator
single intake adapter w/ 48 carb (or dual 38s or 44s, depend on budget)


or... use 61x cases if you are just keeping to a real strict budget, with a 44 sbn.

There are TONS of threads about all this, but most people suggest 61x cylinder, 62t case, ada head, and B pipe.

i have a 62t 61x with my own porting (just the transfers cleaned up and exhaust polished) twin 38s and b pipe and it hits a hell of a lot harder than my mates 760 with the same mods i think 44s would be better but have not got there yet there will be mixed opinions on here but my vote is 701 62t 61x

Thanks!

i like the 61x also. but crammit442 had his 760 motor reported by jetworks. :bigeyes: hits harder then any ported bb ive riden . arts got it going on. some of you guys are really missing out on some raw nasty power. glad my ski is powered by the man.:cool2:

Start with a 61X cylinder w/62T case, stock is a great place to start w/ bolt ons
Then step up to Big Bore re-sleeved 61x cylinder.
And yes! I've also been called "Your The Man" too...

P.S. see the reason in my sig.

Chuck,you a phone number so i can give you a call and talk about some motor options?

 

[brentR]

why the 650 flywheel and stator?

 

[kurtwolff]

apparently the 650 flywheel is the lightest OEM, correct me if I am wrong?

Haven't weighed them, but even so, the 650 and 701 (61X) flywheels and stators are the same, so a 61X 701 setup will work too, but I believe the 701 CDI has a higher rev limit than the 650, so look for a 701 box.

The 650 and 701 61X flywheels are the same, they are slightly "lighter" than the 62T flywheels.

Bore a set of 61X cylinders to 84mm and then you have a nice 760 :biggthumpup:

I have 1 62T 760, 1 62T 701 and 1 61X cylinder on a stock bore.
From what I'm reading on here I should dump the 62T's and use the 61X.
However, there are those who swear by the 62T.
The more I wait the more confused I get. :dunno:

 

[WaveDemon]

I'll be happy to take everyone's 61x cases and 760 or 701 62t cylenders off your hands then. I"m in desperate need of boat anchors.

650 stuff is lighter, lose a pound or half a pound. Unsure on weight but Paul told me about that trick and it's suppse to work rather well
