Default Cooling System Upgrades for an 88

Hello all, my 88 vette needs a new cooling system and I was wondering what you all think of my parts list. For the radiator, I was thinking of the Auto Dynasty 3-row full aluminum racing radiator for about $130 on Amazon. For the coolant hoses, I was thinking of the Continental High-Performance Blue Xtreme Kit for about $90 on AutoZone. For the water pump, I was thinking of the GMB High-Performance aluminum water pump for about $74 on RockAuto. Finally, for the thermostat, I was thinking of the FVP 195-degree high-flow thermostat for $4 on RockAuto. Any thoughts on this list, whether or not these parts are compatible with each other, or are compatible with the otherwise stock engine is very appreciated. Thank you!

I don't know those parts per se, my WP is a Stewart Stage 1, my radiator is a DeWitts and I run a basic stock t-stat now and regular old Delco hoses. My fans have been adjusted in the chip and the B4P has a Hypertech sensor/switch upgraded in the head that flips it on earlier.

But the best and most worthwhile part was the DeWitts.

I fully agree. Was worth every penny.

I just checked on the price of that radiator and it's a tad bit out of my price range. Both you and FostersPerformance say it was a worthwhile purchase, but I still need money for the rest of the car. Are there any cheaper alternatives you recommend? Preferably $200 or less.

I would not, this one part alone made more difference than anything else.

If you don't have to replace the WP or hoses, put the money to the DeWitts.

Here is a current picture of my engine, she's in sorry shape.
I do need new hoses, a water pump, and a thermostat, but I trust that you know what you're talking about with this radiator.

I could not stop the overheating problems in my 88.. Went with Dewitts radiator, and Stewart stage 1 pump, and stock thermostat. No issues since.

I’ve been using a champion two row in my 91 L98 and it’s been rock solid minus having to double up the hose clamps on the lower hose
