Rams Horn Exhausts came with Factory Heat Shields, you could fab up something or buy a set. Your Later model heads are not tapped for the bolts that hold them on, but that problem can be overcome...

The short of it is his current set up cooled his old 350 (5.7 for you Metric Americans) probably around 250-290 hp 330-340 Ft Lbs peak torque when new, obviously less in the condition it was in when it was replaced. And it doesn't cool his current 383 (6.2 Liters) with performance cam, the...

You have a strong running Engine, and a much more heat to dissipate than what was in it before, and cooling it for off-road use is going to be a challenge; be happy you don't have an Automatic then you would have even a bigger problem. :) Yes new engines will run a little warmer during break...

Asmodian your 383 probably has 80-100 More Horse power over your old 350, there is a direct correlation between Horse Power and Heat you must get rid of. If you haven't already done so ask the manufacturer of your Radiator what they rate it for. Off Road vehicles are more difficult to cool when...

I say before the original poster drops a s***load of money on another radiator and fans he should consider eliminating a few things first. Such as removing anything that impedes flow through the existing setup, get it up to speed turn on the A/C and see if the temperature is OK. My guess is it...

Well you said it would "work". Then you made a very reasoned thought out post.

If it doesn't work can the OP send you the Bill ?

The two successful swaps that I have done closest the one we are addressing here are a SBC 383 into a Cj-5 backed by a SM420 and Dana 20 with no A/C; and a 415 SBC Into a 65 Wagoner with A/C and a TH400, that had a performance cam and around 9.5/1 Compression. The CJ has run cool since 1983...

Nice edit job Elbert.

No I have not read all the threads here on engine swaps, I have read a few. I have 40 plus years experience fxxxing around with engine swaps, hot rods, Scouts, Jeeps, low buck round dirt track cars, tractors and god knows what else. And all I have are informed opinions, and an idea about what...

Elbert - respectfully unless you have used the same engine, cam, timing, and Radiator how can you say for certain anything will work ? And perhaps you have and I missed that part. There is quite a difference between a Gen II 5.7 and a Gen I ( I assume) stroker engine. He might even have a...

If you drive at cruising speed and the Temp is acceptable, and turn on the A/C and it gets hot, in my opinion you may have an under sized radiator; or as you just mentioned a serious lack of air flow through the Radiator. If it were mine I would remove the winch and anything else that may be...

asmodion if you drive at a steady 50-70 MPH on a hot day does the rig overheat ?

S/B fit the shroud to the proper fan. I had much better luck with Belt Driven Fans, than with electric Fans, YMMV of course.

asmodion I am new to Toyotas but have some experience with SBC swaps into Older Jeeps, my suggestion is to look at OEM Fans and Fans clutches that are compatible with your engine that were used in Truck Applications. Cooling a V8 in a vehicle not originally equipped with one is always a...
