Here is the cam I am using now.
248/254 @ 50
.600/.604 lift
110 centerline, installed at 106
Is this cam alright? It is a solid roller.

i dont run it on the street yet but i will next summer when everything is togheter..
9.7:1 compression stockstroke 340 with edelbrock heads and a 242/248degre@.050 solidroller
and a twinscrew blower it what i think will make it good..
from what i have been told the fuellines will be costly

That cam should build some decent cylinder preasure, it will not take advantage of the e-85s high octane and cooling ability but it will run very good and make a few more HP than pump gas just because of the extra oxygen in the ethanol. I would not be afraid to bump at least another 2 points compression, personally I like living on the edge and would add another 3 points.

Hey Hotroddave,
The blender pumps that we have here in South Dakota have e10,e20,e30,e40 or 50 and e85. I noticed that the e30 is 95 octane and the e40 is 97.
Since I dynoed my 416 on 93 octane pump gas, will the e30 or e40 give me more boost with the 10.5 cr that I have or will I have to go up?

It can make more power if you tune for it just because e-85 allows you to put more oxygen in the chamber witch allows you to burn more fuel witch makes more power. In order to get the extra power you will need to increase your jet sizes and advance your timing a little. I think at e-30 or e-40 you will not notice the differance in power because it will be small but it will definately help resist detonation.

Even at 8 to one compression e-85 can make more power because of the extra oxygen but it really shines at the higher compression ratios because it is so good at resisting detonation and allows more compression, it does not need more compression to make more power but combine the two and look out
