I am building an L33 5.3L engine for boost. Stock rotating assembly. D1sc procharger. Planning for 600-700 rwhp. I just can decide which fuel to use. i had to drive 30 miles ust to get 91 octane, and 40 miles to get e85. Although if i want to take this car on a triple. e85 will not be available very easily. applicattion is street/strip. Any sugguestions and why?

Also I am thinking about runninig 10:1 compression

you'll need a bigger fuel system (pump/injectors) to support E85, it will burn roughly 25-30% more fuel compared to gasoline. That will effectively make your gas tank 25-30% smaller in relation. So keep in mind if E-85 is not readily available to you in terms of where you live and where you plan on traveling, it'll be a bad day for you if/when you run out. You'll also have to remember the upkeep your methanol tank as well, and I'm sure thats a little less common than E-85 is, but can be substitued for windshield washer fluid, or mixed 50/50 with water if you get M1 or similar grade methanol. Which in reality will only be used when you get into boost, so cruising or low boost wont even use any of it. My best advice is to just stick with whatever you know you can get easier and more commonly.

K, I will probably do 91 with meth than.so if I do that should I run heads that lower compression to 9.5:1 or stick with 10:1
