Tips for starting engine on the ground

Shoot definitely more work but glad I checked with you guys first, if there is vibration from a misfire etc. it definitely could kick off the stands, come to think of it if I give it a big whack of the throttle it'll probably jump right off the driver-side one lol. I'll have to take a look at the mounts to see where the wood should come to; I'm guessing it would be easier to have it contact the block vertically because the slope of the mount brackets would require a support going down the other side of the "mount" block to support it sideways. Or... I could get the K-member from the car and bolt it up to that and have a dolly or something underneath? That was the original plan it was just tricky to get the K bolted up the engine while it's hanging on a stand or on the hoist.
