350 hp out of a fairly stock 340

I won't argue that. I think the main reason a 340 A body does so well against the 383 Road Runners is the weight difference. I had always heard that the driver's side factory exhaust manifold was so restrictive that it really hurt performance. I bet adding headers to one of those back in the day would really have given you a big seat of the pants feeling.
I will
The toad runner 383 was over rated nhra lowered the hp of the 383 dog motor
nhra up the 340 to almost the same as the 383 and higher in the best version
the avg road ruuner was 15.0 the avg 340 was 14.5=sucking the paint off it
you see they want 4spds headers and gears to take the win but still lose
383 727 3.23 in anything cuda road runner is a 15s second turd
stock 340 727 3.23 14.3 97
340 727 3.55 700 dp 13.1 104 otherwise stock 15 cars no headers no 4spd
stock 383 cars were slowwwwwww in any body
wonderfull traction in that 383 4spd 3.55s with headers on e-70s worse 60 foot from stock maybe a 2.5 meanwhile the 340 3.23 car rips off a 2.00 60 foot 5 cars and turns a higher trap spd
about the same as a wheel hop gm big block on those tiny tires up in smoke 5 cars behind in 150 feet race overrrr
how many records does the 340 A- body hold many many
how many records does the 383 any body hold? crickets crickets zip
The ss 396 chevelle trapped 100 mph 400 gto 97 to 100 they also weighed more then a 383 b body the 383 with a 4spd and 3.55s trapped 94 lol
ford 390 mustang was a turd
340 was the baby hemi and smoked many many big blocks the 1st 100 feet the race was over
