Glad to helpThat's an angle I really hadn't thought of. Thanks. I might just do that.

if I'm looking at the correct cam, the powerband is 1,300-5,600. That's no drag racing cam so it should work just fine in your 340Based on the info I am getting. An XE262 won't work in a stock '70 340.
That's the one. 9.72 SCR brings me to around 8 DCR. I understand that's too much for pump gas. My plan was to build a punchy street engine. Auto with 3.23's. I have a voo doo 268 as well, but the intake valve closing on that one seems less than the xe262 which again raises my DCR.if I'm looking at the correct cam, the powerband is 1,300-5,600.

I'm running a low lift (.421/.443), low overlap, low duration (204/214 @ .050) Erson RV cam with 9.8:1 CR, just use a 30% ethanol mix and you should he just fineThat's the one. 9.72 SCR brings me to around 8 DCR.

What does this mean?just use a 30% ethanol mix and you should he just fine
E30 (30% Ethanol fuel) is a dirt cheap version of 93 octane fuel. It's a 3:1 ratio of E15 (standard pump gas) and E85. 3 gallons of E15 (standard pump gas) to 1 gallon of E85. This will help avoid knock that you would otherwise get with high CR engines that feature a low lift/duration camWhat does this mean?
I don't even know if we have that here?...87, 89, 91 (91 supposed to be E free).E30 (30% Ethanol fuel) is a dirt cheap version of 93 octane fuel.

Do a 1:3 ratio then. 1 gallon 87 to 3 gallons of 91I don't even know if we have that here?...87, 89, 91 (91 supposed to be E free).
So, in your opinion, the engine will run fine with 9.72 static, xe262, and 91 octane?Actually that made no sense on my half. Just run straight 91
I would say so. My combo is that aforementioned RV cam advanced 7 degrees with higher compression. It has a lot of knock variables in it but with a little advanced timing and some higher than pump gas octane fuel and it runs like a raped apeSo, in your opinion, the engine will run fine with 9.72 static, xe262, and 91 octane?
