    Frankenstein 454 swap. Overheating at idle.

    Well....turns out it has more than one hole Now that the big hole was plugged, for sure can hear more leaks from the core. This rad is shot. Smh......$50 more up in smoke.

    Its a Frankenstein 454 w/ th400. Once ive recooped some of my $$$ I'm going to put a nv4500 in it and convert to TBI. Lol as she sits she is only getting about 5-6mpg. And thats rough for a daily driven work truck. Under "tech discussion" there is a thread detailing some of the issues ive...

    I like the markers...a lot. Would look super cool on my suburban. Highly doubt that my local PD would stop me for red markers. I've got away with much worse. (69 Lincoln had greed turn signals) The previous owner of my burb gave it a half way decent rattle can paint job that is remotely...

    My 83 burb has the split ambulance door...The mechanism that operates the passenger side has proven to be a bear to find. If you come across one in your searches HMU. I'll keep my eyes peeled for your window motor.

    Frankenstein 454 swap. Overheating at idle.

    So...pressure tested the new old 1ton radiator prior to instillation. And its good I did. Has a good leak around the lower trans cooler port. Going to try amd drop some solder on it tonight and try again.

    Frankenstein 454 swap. Overheating at idle.

    Awesome. I did get the propper size radiator. Its used, but seems to be in pretty good shape. It was originally paired with a 454 in a 1 ton. Got it for $50. Got coolant on sale at Advanced Auto for $8 a gallon. Lol things might be looking up.

    Frankenstein 454 swap. Overheating at idle.

    Could dual fans out of an 05 Tahoe be made to work with my new old radiator? Currently at pick-n-pull with one in hand. The plastic shroud is 34.5 x 20 and the fans are both 16" S blades. The fans plug in....i assume I could just snip the pig tails off and wire into my painless wiring...

    Frankenstein 454 swap. Overheating at idle.

    Found an "80s BBC 1ton radiator" on FB marketplace for $75. Appears to be the same size as the one I pulled out. Does anybody know if there will be fitment issues between a 1ton and 1/2ton?

    Frankenstein 454 swap. Overheating at idle.

    Got the overflow bottle pulled out and flipped So that its actually functional. I bought a new OEM one....but I'm pretty sure the batt is sitting where it would mount up. Looking for universal set ups. Would be nice to actually be able to see the coolant inside. Im def going to rip the baby...

    Frankenstein 454 swap. Overheating at idle.

    Im running a "painless" wiring harness for the fans. This truck has a dual bat set up and I think an over sized alt due to having front and rear AC. But I may be wrong. Looking at replacement fans....most seem to be labled in amps, not wats. Amps x volts = wats correct? Ive found some...

    Frankenstein 454 swap. Overheating at idle.

    Thanks for all the knowledge. I went ahead and added the plastic shroud back on. Had to be trimmed to fit. Then, I taped up the vents in the face of the shroud. Once it dries out im going to tape up the 1/4" gap on the bottom. Truck never got over 210. But the high today is about 45°...

    Frankenstein 454 swap. Overheating at idle.

    Ive wondered about incorrect gaskets. But she really seems to run well. Temps stay at 185 constant when running down the hwy. Even at like 35mph she stays cool. I would imagine my over heating would be worse at speed if gaskets were the issue?

    Frankenstein 454 swap. Overheating at idle.

    Ive done a lot of crawling around looking for numbers of any kind and have come up with squat. Im going to get it out of the snow this afternoon to work on it and I'll do some more checking. I'll bust out the Degreaser and a brush if needs be. But its really not all that dirty. I know the...

    Frankenstein truck headaches???

    I really like the late 60s (buddy has a 69) GMC front ends with the round lights. Otherwise I like the quad square look. But its more headlight adjustments to make.

    Frankenstein 454 swap. Overheating at idle.

    Going to double check the electric fans. Make sure they are, in fact, pulling air. There's certainly not air being blown out the grill. But I guess one of them might have the blades backwords? Im also going to take some aluminium tape to the vents in the shroud. As well as tape off the...

    Frankenstein 454 swap. Overheating at idle.

    I've got a coolant over flow bottle on the way, the bottle on the truck is more home made nonsense. Had a drain cock on the very bottom...that was shut...smh, opening it will just have it pissing coolant all over the place. Idk how detrimental this might be, but I know it's not right. Just...

    Frankenstein 454 swap. Overheating at idle.

    I don't really know how to tell. It seems like they are pulling pretty hard. Its a nearly brand new 3 row aluminium. The gap between the shroud and the fans is minimal. Should I try to fill the space with backer rod?

    She got up too 220 and I shut her down. So....could the pully be too big? Whats the propper size pulley on a chevy serpentine system?

    Got the pump that Bextreme suggested. It has me on the road again. Been running at temp in stop-n-go conditions for about 30 min. Holding steady at 185.

    Frankenstein 454 swap. Overheating at idle.

    Lol guys....I swear to God I did not do this to this truck. My biggest mistake was not knowing what I was looking at when I bought it. But between this truck and my 55' Bel Air im learning a lot about turning wrenches.
