On alcohol and cool nights we have trouble getting our engine up to temp. Would like to run around 200 but sometimes struggle to get to 170-180.

What works better. blocking airflow through the radiator with tape, cardboard etc? Or running say a 180 or 195 thermostat at least until summer months when it warms up.

If your jetted up to rich it is almost impossible to build heat in the engine.You might play with jetting a little bit but use extreme caution a little lean will make them overheat instantly....Hope this helps...towman

I am pretty sure we are not off on jetting as we adjusted it on the dyno. Last time out we taped up almost 1/3 of the radiator and got it up to 180 on the track but just wasnt quite enough. I know just sitting idleing it will never warm up... never has. In the shop or at the track we put cardboard in at idle to build heat. I

Is it hard on the radiator to block air through it? Does it cause hot spots in the radiator which can distort the aluminum?

I have the same problem! I have gone to the 180 termostat and still need to block off the radiator a bit.

Sounds like your never building enough heat to hurt anything, I wouldnt be woried about the radiator at all.I have cut a piece of sheet metal that covers the front of the radiator for warm up in the pits,but be sure and take it out before you go on the track haha.I would go ahead and install the thermostat for now summer is comming....towman
