Topic: 11HP BLOCK WITH 12HP CRANK AND ROD

[NICERIDE]

Does anyone know if a 12hp crank and rod fit in a 11hp block.  Would there be any advantage to doing something like this?

It will increase the stroke, but you will need a shorter rod and piston combo or it will push the piston thru the head...

[jamie_guy3]

do you no squidd what is the part number for briggs dose it take to do that .................

[jamie_guy3]

what is the shorter rod and the piston is it made from briggs do you no the part number you can put in a 11hp block with a 12 hp crank thanks denis

I don't know the numbers off the top of my head, George might...

But it was discussed and I believe the part numbers given in another thread on this forum...

Might have to do a bit of searching, but I'm sure you can find it discussed a time or two...

If I run across it I'll link it here...

There is no shorter rod. If you are going to do that might as well build a 12 thats what you will have if you accompliush what you are speaking of. NOW using a 11 crank in a 12 with a custom longer rod will make a killer short track motor. But you will have to find someone to build the rod for you. Allready seen one of these motors and it rocked on the short tracks.

weve been waiting for that rod(11hp crank,avs piston,12hp block)maybe someone from ARC is watching. :wink:  :wink:  so,goerge what cid would that be with a 31 piston?

Why is the shorter stroke engine better on shorter tracks vs. a longer stroke engine?

[Squidd]

Technically, a short stroke motor should/will rev up faster...

But a longer stroke makes more torque...

tory to figure cubic inch the formula used is bore x bore x .7854 x stroke x # of cyls.
