I guess the 1st. question is, what is the air temp and that of the engine? is it 20 degrees or 80? The colder the engine is the harder it is on the expansion of the moving parts. Meaning start up at a dead idle till you feel any heat on the jugs.

Pro Stock race cars come to the line as cold as they can. They fire up, roll into the waterbox and do a burn out at 9,000 rpm...and they don't have roller bearings...except for the camshafts. They do run the cars up to temp in the pits, but then cool them off as much as they can before they hit the line.
I think the main thing is that you have good oil pressure...and don't go nuts. The EVO's had problems with cylinder base gaskets if you got on them before they were warmed up, but I've never heard of problems like that with the Twinkies..

Those engines get rebuilt on pretty regular basis, don't they?
