1971 360 question

We all know the 340 was the highest performing SBM. The 360 came on the scene in 71 to replace the 340. When the 360 was put in Dusters did it now become better then the motor the 340 was? So would a 72 340, lower compression and what ever detuning was done, beat a 73 360 Duster? I had a 71 340 duster and it was a great motor, but never really saw a side by side comparison of 340 vs 360 back then.

I have often wished someone would build a 340 & a 360 at both having a 10-1 compression and swap top ends and camshaft over to the other using the same exhaust manifolds or headers for the best possible A to B dyno test just to see where the cards fall.

IMO, I think it would be a fun testing.

Some stock small blocks came with 850 cfm thermal quads. 340 Six packs were 1350 cfm. with 444 lift cam same as 4bbl cam and same ports and valves

IIRC, the 6 pack works out to be 955 cfm when converted to the 4bbl measurements.

I think the TQ’s, big or small, work great for what they are due to the small primaries. It’s also my opinion that for a OEM stock carb offering they perform realllllly well.

I miss the days of $20 TQ’s. Crazy cheap to get and rebuild kits were 20/25 bucks. Add in a few tricks and off to the races with a cheap *** kick *** carb bowling the song of my people at WOT!

Ahhhhhh, that soooooogning howling sound.
Mmmmmmmmmmm
