And it can happen in just second(s) at WOT......6000rpm is 100 per second, and a rod bearing can weld itself to the crank, spin around, and jam it up, get hammered flat, squeeze itself out the side, and make an awful racket. And don't ask Me how I learned that,lol .
If you're gonna spend a lotta time over 6000 then you need to make some oiling mods. I think there is a sticky on that; if not then there should be.
A 276 cam probably peaks around 5500 in a 340. With a regular A727 (close ratio,lol,trans), the shift point is usually about a 1000 rpm higher, so 6500. That will want the mods to keep the rods alive. With the A998(wide-ratio trans) and GVOD, the powerband requirement is only about 1300, so you can shift it at around 6100. That's another good reason to split gears.Now the mods are optional. And if you go the hi-flow aluminum heads/ smaller cam route, then the power peak will drop 200ish rpm and the shift speed as well, so now you're under 6000 with that splitter-deallio.
Yes I know the 200rpm lower peak is worth 20 hp or so.....SO what, the splitter is worth like 40 or more, over a 727.
Ok maybe I'm being obtuse.
What I mean is; OPINION coming;
:is, that the 340; with hi-flow aluminum heads and a 270 cam and the 998/splitter deal,and a 2400TC will trap the qtr as if it had;a 276cam (maybe even 282) cam, X heads,a 727, and a 3000TC. Yeah I'm guessing. I guess I should re-load my DT-Dyno program one of these days; then I'd know,lol.
dual quads have been on the streets for years, nobody say'n they don't or can't work. Just like six pack set ups. They are cool, but it is totally not necessary in todays world to make power. Those that do either six pack or 8 barrel do it for themselves or the wow factor of others. And if the OP wants 400 hp and believes dual quad is the only way, we are just saying it is absolutely not necessary. In fact, today 700-800 hp motors are nicely fed through one carb.
