Crossover kit
Im running two 454 with blowers about 600hp. I recently changed out one of the blocks. Here's the problem I'm using crossover kits and run 120-130 temp. Since I switched blocks its running 100 and below that when I'm going over 2rpms. All I did was change the block out due to a spun bearing. The cooling system stayed exactly the same...so why is the new block running so much cooler? Any ideas?
Thanks

Or maybe a sender issue since most gauges/senders don't register under 100 ?
Or, there was a restrictor under the t stat housing that was not reinstalled ?

No restricters and the stat goes to 100-105 and then when I speed up the needle goes all the way back down as far as it can go. When I idle again it slowly climbs up to 100 again. Sender and stat are also good because I switched motors and tried them

Having the same problem tried everything I could think of for the last month. I am using a harden marine crossover with bypass, stainless marine dry.
I have cold water going in the block on one side of the crossover and hot water leaving the block and out the bypass on the othe side of crossover.
