RE: Higher octane??

Hey Don

I run 87 with no ping. But I'm not sure of the compression ratio of the 1970 440. I seem to remember it being 9.5 to 1. Would putting an aluminum intake on my baby increase the power? I know it would cut down on weight.

I have 9.5-1 compression and steel heads on my 440, must run 93 octane. Will ping on 91 octane. I run 37 degrees total advance.

Just woke up from a snooze and read the responses and have some added questions. What do you mean by cooler plugs? And as far as ping goes, there is none that I recall. Car's been parked for a couple months now for winter. And somebody, I think Mike & Deb, mentioned gear ratio. Well it's a 3:23 gear. Do I need to put a higher stall converter in the tranny? It's the stock converter. And someone also mentioned compression ratio. As far as I know it's whatever the factory ratio was on a 1970 440. 9.5 to 1 if I remember correctly? I know this is a lot of stuff I'm asking but would really appreciate some advise. Thanks

Cory,
What is your gear ratio? If you have no audible spark knock you probably have sufficient octane, yet we know gasoline isn't what it used to be. While we're talking fuel have any members used or have any knowledge of the Aquatune products? Very impressive claims!

Now I think know the answer to this question, but I'm gonna ask it any way. Should I be running higher octane gas in my 440? It's a 1970 engine with a bit of a cam, new rings, and stock heads with high rise exhaust manifiolds. It's in my 65 Polara.

The reason I ask is cuz it just dosen't seem to have the balls I think it should have. I run 87 octane gas in it. The highest octane you can get here in Canada is 91, I think. The reason I've been running this low octane crap is cuz gas is quite steep in price. $1.16 per liter, that's $4.40 per gallon. And that's the cheap crap. I think premium gas is like 10 cents more per litrer.

Having said all that, should I start buying premium gas or just put some octane boost in with every fill? Or should I do both? Also, am I hurting my 440 by running a lower octane? I had a few other questions but I forgot what they were. DAMN!!
