Check it out, im in the process of getting my new motor together and the only problem is is that im running out of time before import vs. domestic. Right now my block is out at golden eagle for sleeves and when it comes back its getting eagle rods, wiseco pistons, acl bearings, and arp hardware. Its also being matched up to my fully built head with ferrear valves and a bisimoto cam with a spa top mount and garrett 57. On the original engine with only pistons and rods it held 25lbs on stock sleeves. This is where the problem is, i have a feeling the engine wont be back in time so iwas going to slap together a d15b and see what happens. Question is how much do u think this block, pistons and rods will hold before it lets go. I would like to go to mir and be competitive and im just not sure if its possible. Need your comments please.
