I am about to overhual my car. 1970 Chevelle/Malibu

454 Block
TH 350
12-bolt Car

This combo should be able to kill any damn riceburnner, or current production wimplecar built by the big 3 today.

But it has to be streetable as a daily driver as well. Any opinions?

If you dont get crazy with compression ratios and keep a reasonable rear end ratio such as a 308.1 or something like that, it should be a good but thirsty daily driver.

progress has little to do with speed, but lots to do with direction.

3.08:1 ratio? I was hoping to keep the compression arond 9.0-10.5:1 This may be high, but I have to keep it up there to counteract the weight of the Chevelle. Those riceburneres only weigh about a buck-0-five soakin wet! As far a fuel consumption goes, its a 454. What is FUel economy?

he was speaking of 3.08 rear gear ratio, not compression.

blazingchevelle,

If you are going to use this on the street as a daily driver keep the compression ratio reasonable.
Iron Heads: 9 to 1 max
Aluminum Heads: 10 to 1 max

You'll be happier in the long run as you won't have to run an additive in the gas, and you won't have to retard your timing as much.
