For several years, I used to take the HotRod 360 out of my DD Barracuda, in October, and reinstall it in May, having freshened it during the winter.
The winter-engine was a Smog-era 318 with a TQ on it, a small-port CI 4bbl intake, and I left the TTIs/dual 3inchers/ with 3in-3out Dynomax turbo mufflers, installed.
It ran great, and sounded pretty good.
I think for two winters, I ran a hot-rodded A904 with a 2800stall,
One winter I ran the Regular A833
Sometimes I ran the A833od.
Eventually I got a GVod and slapped that on behind the A833od.
Sometime later , I got a Commando box and ran that with the GVod.
Depending on my mood, any rear gear from 2.76 to 4.30, might be back there.
That 318 had a stock cam, stock heads, stock everything, except:
the 4bbl, some upgraded springs to control the tiny valves at 5500;
adjustable 273 valve gear, and
the 2800stall.........
and the truth is that, for a winter-engine, that low-compression marshmallow was a total hoot.
Did the headers make any more power, than 340 logs (which I had) would have?
Like said:
Don't know/don't care,
but I can tell you that with 4.30s, she did pull real good; and
with Seven usable gears like this;
3.09-2.41-1.67-1.30-1.00-.78od-.54od, 65=1880rpm,
Whatablast!
But, and I did have to run some meaty studded tires all-round.
BTW
to make the most of this 4bbl/combo,
I did have to rework the carb, AND especially the Timing curve.
