1973 360

What was the fastest accelerating vehicle in 1978? Little Red Express pickup with essentially the same motor as the 74 hi-po 360.

The really dog 360s not only had the low compression ratio, but retarded timing, wimpy cam, lean carbs and then catalytic converters. They had way less than 200 horsepower even with a four barrel carb.

That was the later years no doubt. The 340 cam was also used in HP 360’s. Not all 360-4 engines got the 340 cam. (Cali- standards for emissions were also higher thereby reducing HP further.)

For what it's worth, the 74 Duster 360 motor in my 67 Barracuda just ran 13 flat at 106 with the same low compression stock replacement pistons that have been in the motor since 1991 (.100 below deck at TDC), a 450 lift cam that's one step above stock (also been in the motor since 1991) and 3.55 gears.

Nice!

The 74 360 4bbl was rated nearly Identical to the 73 340. except of course the 360 torque-peaked earlier. Those two engines had all the same parts bolted on to them, making the only significant differences, being their strokes.
Furthermore, the only significant differences of the Net engines and the Gross engines was the compression ratios and ignition timing.
IN other words, swap out the 8/1 slugs for 10s, put the timing back, and Shazzam.

You bet! Read on below.

The heads on those 73/74 engines were the same
BTW,
I challenge any streeter, with typical street gears, with one with one of these 1.88valve head cars, to swap out the 1.88 heads for 2.02s, with no other changes, and on the street, find the difference in ETs from zero to 60mph, . Good luck.

I never tried the difference comparison. But this is essentially what I’ve being my 20’s. I took that low compression (‘79) 360 engine and gave it a set of KB-107’s-.030 at zero deck which fixed the compression issue.

With the 1.88 J heads, I installed the Purple 292/.508 cam, Torker II (later switching to a RPM-AG when that first came out.) & headers w/a Holley 600 left over from a 318 build. I later used a AVS which I loved. All in a ‘73-4spd-4.10 Cúda.

Later uninstalled 2.02’s. Then when Edelbrock introduced there RPM head for the small blocks, I grabbed them. I used a heavily modded LD-340 before I gave t the RPM-AG with a big TQ.

Excellent set up by the way. Whipped a modded ‘86-ish Camaro that very night even before I got to the cruise meet spot.
