Alright i have been contemplating the fact of getting a genesis for a short period of time and i was on the curiousity aspect of wheather or not anyone has tried to drop either a .70 or bigger engine in a genesis if yes how did it work???

The other question does anyone that has a genesis or has seen one in person seen if there is room to drop twin bigblocks in the genesis? has anyone attemted to drop twin rigs in a genesis?
and for the other question is how did it run?
or would you just recommend dropping another .46 in it instead of anything else? if so the reosoning for the keeping the .46.

it seems like the ek4 does really well for speed and torque with either the .70 or .90 in it with a 2 speed tranny. thats why i was wondering if it would be equal to a setup like that with a 3 speed.. any help would be greatlly appreciated thx
