Glad I could help. I built the work bench in my clean room just so you could store extra engines underneath it. Actually could use a few more!
www.northerntools.com has a really nice steel wheel caster rated at 1000#, $3.49 for rigid and $3.99 for swivel. 4 swivels would make it easier to store under the bench, but the two rigid make it a LOT easier to steer across the shop...
The motor is a 96 Camaro SS LT1 with CNC heads ported heads and a crane cam. That is the GM Performance parts carbed LT1 intake. I'll get the car running with the carb, then convert to FI when I can afford to do either Commander 950 or DFI Gen VII. The shorty headers are only for show. They don't clear the angle plugs. I have another LT1, and iron headed straight plug motor that will get the carbed intake and shortys and put in my Datsun with a WC T5.
