Look into some meth injection kits or run alky.
Dont know how feasible alky would be but I bet you could get away with it with some meth injection and some good fuel, conservative timing.

Choose a cam with alot of overlap and a numerically low centerline,then you could probably get away with it.

You are kinda playing with fire. If you have a really good tune and don't run much boost you "may" be ok. You may want to consider going with NOS instead.

Just run a mix of pump/race gas & don't worry about it.
The way to make some serious HP is to run high compression & boost. You just can't do it on pump crap.
By my calculations you'll need 100 octane for 10psi & 26 degrees total timing on this setup.
10psi, 100octane, & a STOCK timing curve & that thing will flat out hual-ass & last as long as the block doesn't split.
Probably the cheapest way to make 100 is to run a mix of leaded fuel & pump gas. (you just can't run cats) I highly recomend Sunoco Maximal (116octane). It's a fast burn fuel with very high anti-detonation properties. Mix 5 gallons of Maximal (~$8.50 a gallon) with 10 gallons 91 octane & you'll have just under 100 octane. Motor octane if FAR more important & this mix will have plenty of it. If premium fuel is $3 a gallon, you'll end up spending an extra $27.50 per tank of fuel. Small price to pay compared to the $$$ in your setup. If it's not a daily driver & you're like me & fill up the car at most once a month.....that's not a lot of extra $$$ to run a bad-ass timing curve & make tons of reliable power.
