SN95 1995 Gt Cooling Help

[85fiveohman]

ok guys need help my 95 gt converted to carb has mishimoto radiator( 2 months old) new water pump new belt and has a autometer electric temp gauge the ? is when i am running it hard like getting on the express way or just gasing it pretty good the temp steadly rises, but when i let off and slow down the temp slowly drops back down to 190 or so i am stumped. when setting in traffic or just normal crusing around it runs 190-195 and never gets any higher.

Did you check your timing? It is normal for the temp to go up a little when you hit it. It also could be a lot of carbon buildup. Is there any smoke coming out of the tailpipe when you hit it?

run some sea foam through your motor to clean all the carbon buildup

I don't think timing is off as the car runs fine no miss or anything and I will try sea foam
