    Overheating Rebuilt 350

    Update: Timing and idle appear to be on point. Purchased a temp gun from Harbor Freight. At idle after about 15 mins, thermostat housing was reaching about 202 degrees. Location around temp sender on driver’s side head was about 220. Stock instrument gauge was showing 230-250. I took truck to...

    Wow, lot of great information. I’ve got a Edelbrock 1406 Performer Series. Similar instructions?

    Will do. I’ll do some research and give it a shot. I did lower idle…just haven’t messed with mixture. Nervous about messing with carb.

    Thank you for the suggestion. I’ll give it a go once I get my coolant system locked in the next day or so.

    Overheating Rebuilt 350

    Yeah, wasn’t expecting that. Adjusted to 10 BTDC and it sounds much better. Temp still climbed to about 215 (guessing on stock gauge) but even slower. I’m gonna get a temp gun to verify. Appreciate you and Rust on the timing education. Didn’t realize how much that factors in overheating. I...

    Timing is retarted at -4.

    Overheating Rebuilt 350

    Update: New reverse water pump, reverse fan clutch and reverse fan installed. With front end lifted; using water; no thermostat; upper fan shroud installed and a fan blowing air in the front of radiator, I was still dealing with overheating, however, not as quick. Was able to finish break in...

    Overheating Rebuilt 350

    It appears you found the culprit…me, ordering a standard flow water pump. It most likely is a coolant flow issue based on whats happening and your keep observation. Much appreciated for catching that and suggestions on purchasing options. I’ll see what my options are between Local, Summit and...

    I’m pretty sure thermostat was installed properly. Just removed. Pic attached.

    Yep, stationary break in. Middle GA. Gets hot, but not enough I’d think would factor in to my overheating issue. It’s in shop, with some air circulation. I’m leaning towards water/coolant circulation issue. Correct fan and fan clutch are a must.

    Good point on fan clutch. Yes, I really like this GM serpentine setup. Very clean and relatively inexpensive…compared to aftermarket. Got the same setup in my Jeep YJ SBC. That and a little research led me to doing this to my K5. The YJ was definitely a good reference point. Just tried to mimic...

    Overheating Rebuilt 350

    As Bennyt pointed out, I have the wrong fan. I’m guessing address that first and try again? Would it still be a good idea to remove thermostat and let it flow for the remaining breakin cycle if all is well with water pump? Yes, RPMs in the 2000s but only for about a combined 15 mins. Thanks...

    You’re correct, I have the stock standard rotation fan, which is wrong for serpentine setup. I need a reverse rotation fan. Good looking out and Thank you! How did you find yours? It looks stock.

    Overheating Rebuilt 350

    Stock fan attached. Some resistance when I spin it with engine off and cool. No box fan was used. Lower shroud only. Same number stamped on water pump associated with pump I purchased. Pics attached. As far as the heads, they’re stock GM (3973487: 68-79). They were rebuilt too. Nuthin fancy with...

    Overheating Rebuilt 350

    Hello. Got an 86 K5. Originally came with a 305/TBI, but a 350/carb was installed back in 97 when I purchased. 350 block came from a 69-79 vehicle, based on my research. Block and heads rebuilt by machine shop this past April. Motor removed and installed by me. First time…somewhat mechanically...
