I have a "Scoop" on my (Street/strip) El Camino and below 25 MPH it doesn't work all that well, That's where a good fan/shroud and good air flow comes into play when low speeds and heavy traffic in town.

My 83 Itasca (454) came stock with a 5 blade fan, Dug up a nice 18 inch 7 blade fan....Have you checked yours?

More than HP though ,I want tourque...wish this engine was a 455 olds with that huge stroke motor!
"Chebby" developed a very good high torque STOCK manifold which works well up to and around 4,400 RPMs, I would leave it alone.
Once you get the air dam in place and create a "Low pressure area" behind the radiator I feel e'nuf cool air will enter the engine area.
Remember, You are running at a higher altitude plus it's not as hot as the climate I live in....
IF you can find a stock thermostat housing with 2 drilled holes in it that's where I would install the digital temp gauge, Or else get a stocker and drill and tap the second hole.

Several rigs back, we had a 31 ft, 83 Pace Arrow. I enclosed the entire area from the front of the "bumper" back to the underneath the radiator. It made a significant difference in the amount of time the fan clutch engaged. With that, I also found I was better off to run a little faster on flat ground.

Even though we have a Ford I really enjoy reading these performance upgrade discussions. Many of the ideas work for mine too...

So how does this engine come out of the chassis? Mine doesn't have a drivers door (don't like that) I heard someone say it comes out he drivers door??

I haven't had much time to look at it since I got it last week. I have to tighten up the fan belts (squeeling) so we'll see how fun it is to work on...

P.S I found a website called "thefind.com..." and they have an 8 blade electric fan from a 96 Pace Arrow...hmmm 119 bucks US. Looks like it has a bracket for it to mount as well...Anyone ever deal with these guys.

I like the idea of the electric fan...quieter,doesn't rob horse power,and faster warm up times...I would keep the fan "in stock" incase the electric one lets me down on the road...

P.P.S- What is the real HP and TQ of this engine? Torque is my main concern.

About 20 horses is removed when the engine fan kicks IN, The trick is in the cooling mod's and keep it OFF.....
230 HP and 360 torque as written is about right which amounts to about 1/2 horse per cubic inch (very lazy engine).
Without tearing into the engine I see NO reason why it cannot be bumped up to 325 horses and 450 FP of torque which is still a pretty lazy engine...

Hi Dave, Yes the "Windshield wiper fuse" would work fine since the ignition key in the OFF position will remove ALL 12V power...
That "Choke unloader" is pretty fussy and might need an ever so slight tweak so use a lite hammer

Back to the cooling issue......When I tore down my 83 to replace ALL/everything that rotated on the engine I took the radiator down to the shop for the inspection...
My, My.....What was found out while it's a 4 row the "tubes" were only 3/8, After a good laugh the critter now has the same 4 rows but with 1/2 inch tubes.
Just thought I would toss that into the mix...

I have feeling I know the answer, but there is a very important adjective missing from the above sentence, between "really" and "the".

My guess is "DROP" or "LOWER"...but the OP should probably confirm for anyone not really sure...
