Torsion bar installation question
and that is why I like the thicker torsion bars more than headers, unless it's a "racecar".:steering:
Ima thinking you(A56) know this; but for newbes reading this;
Without headers, the Overlap cycle is sacrificed. All cams have overlap, even the factory 318 cam. Some say that headers put an easy 35 horsepower on an early 340, and that 340 cam sported only 44* of overlap. IDK if that is true, but I could believe it. If you had a 318, even 5hp would be noticed, lol.
But to be fair, the bigger the engine is, in an A-body streeter, the less important this is.
Same as goes with compression or stall.
Since I only have a 367, with a nice-sized street-cam, Headers are very important to me. As is the cylinder pressure, and I have a clutch. and 1.03 bars. And an overdrive transmission, allows me to run any street gears I have a mind to, so I get to exploit that overlap cycle TWICE on the way to 60/65 mph. That cannot happen with an automatic tho, so I see
@A56 's point. I mean it could happen, but you'd have to run a rear gear, something like 4.30or more; which will take your streeter, out to the extreme outer limits, of streetability.
Long live the manual trans!
But again, running a 416, makes this, sortof moot.
