Will 760 fit in 93 square

[Rheeder218]

My buddy is lookin at maybe getting a 760, and he was wondering if it is possible to put in a 93 square nose.

 

[michaelart]

yes

The 760 motor will bolt right in. Only exception would be that you would have to change to a 62t exhaust manifold.

 

[Big Kahuna]

as a complete motor swap, yes, you just have to reduce down the threads for the exhaust manifold or drill out the manifold for larger bolts.......... or you can just use the cylinders and bore the cases to fit..........still have to modify the bolts for the exhaust.

 

[Rheeder218]

so the exhaust manifold jsut needs bigger holes to put the bolt throught ot bolt the exhaust to the clyinder. what about the size of the exhuast compared to the 760 exhaust ports?

http://www.x-h2o.com/threads/14783 sorry theres a 760 motor and a 701

WE found this motor to drop in, will it also needs the bed plates?

 

[Matt_E]

You can use your current bedplates. They're all the same.

what if he uses a factory b pipe mani? that bolts up to a 760 cylinder, correct? or no?

 

[Matt_E]

You need to enlarge the 8 holes in the manifold.
Or put inserts into the cylinder holes.

yep, that will work

my last square had a 760 in it .simple to do.

whats that the exhaust drilling?

 

[norcal ex]

Yea, you just drill out the 8 holes to larger ones, or put timecerts or whatever they are called into the holes to use your stock bolts...

 

[WFO Speedracer]

It is a lot easier to use the timserts and your bolts those stock bolts for the 760 are xpensive if you don't already have them.

 

[Matt_E]

Timeserts are pretty spendy, too.

 

[guiness92]

I hope it works, I got one in mine that Paul put timecerts in for me

 

[Rheeder218]

I take it with droppin in this motor the carbs will have to be re tuned? What about props as well?

 

[Matt_E]

The carbs should be tuned to the motor already. However, they'll be setup for a sitdown. That includes staggered jetting.
So yes, a bit of tuning, but probably not much.

 

[Mouthfulloflake]

you cant just use some strong metric bolts?

what diameter/pitch are they?

I plan to drill all of my manifolds to fit 62t cylinders.

so thye just have to be tuned not jetted right?

 

[Matt_E]

No, you will probably need to rejet. One main will be 135, the other will be 132.5. That is necessary in sitdowns because of crank torsion or something like that.
Your standup has different requirements.
Also, I think the compression is staggered.
