4 bbl intake 273
so what ratio do reccomend sir? This car I'm never gonna probably be driving over 80, it does go on he highway so id like about 70 maintable without the engine screaming but also I'd like it to get there faster than it does now. You said 3.55 for first leave the other two
The same? Or do a 3.55, 2.45,1.45 with a 2800 stall? (I'm sure you've guessed by now but all I know about tranny's is I shift and I go faster.)
Jake you are in trouble..
To be happy at 70 you already are maxed out with a 2.73 rear gear. These will get you 70@2720 with zero-slip, so perhaps as much as 150 rpm less on a good day. So you then are stuck with TC to get off the line, where perhaps the biggest time improvement may lie; and/or the aforementioned 4bbl to fill in the speed from 18ish mph to 70mph.
Now if she is fast enough for you to say 20 mph, then the only choice you have is more power. And the 4bble WILL help you with that.It ain't much in your combo, but every little bit helps I guess.
But to get off the line a lil quicker to 20 mph, well, that would be the job of the TC. I like a 2800 with a 318, but that might be a lil much for your 273. IMO, a 2250 will be a big improvement over a 1750. And a 2500 yet better. And neither are a hindrance to fuel economy at 70 mph with 2.73s.
>But I
gotta tell you, a good TC, and a 4bbl set-up could cost you more than a good used 318-2bbl. Which is huge boost in power and torque, and then both the 1750TC and the 2.73 are perfect. Oh, and the 2bbl can stay too.
IIRC there is about a 50 hp difference between these two,similarly built. This would easily be over three times what the 4bbl and the TC could do for the 273.And the increase is from zero mph, all the way to 70 mph, no waiting for the 4bbl rush. There will be a slight economy penalty tho.
