Magna engine into scorpion

Post by bmxwrx »

Hey guys,

Looks like my engine has shagged the rings again due to sloppy machining. So i'm thinking of getting a new short block from a magna. Block is currently at 60 thou oversize and the pistons slap like all buggery, LOTS of blowby.

Now i know the water feed is on the back of the magna engine compared to on the front of the sigma motor. How have you guys gone about getting a magna engine in to a sigma/scorpion?

Is there any other problems i should know about or should i try and find a sigma engine instead?

Thanks

the GN sigma used the astron 2 ( magna block ) but had a welsh plug banged in the rear water pump hole
you will need a sigma narrow sump front timing to slide a water pump on the front
