Thats true I really wish e85 was readily available around here. There are a few gas stations with it but nothing convenient enough to use it for a build.

What You & me are wanting to do does not come without Risks Phil.
Fuel consistency is very important .
Only safe way to tune for E85 is set AFR for 53% alcohol blend initial.
Then keep tuning on the same batch of E85 Fuel.
Could be a real PIA.

Need a Mule test engine without dumping thousands into to it to test and tune and record real world driving and track 1/4 mile results.
If it blows its a simple writeoff failure.

Both the 70 & 71 Pontiac 455's are too hard to come by & Valuable to blow up testing E85 Turbo charging to the limits.
410 sbc I won't use. My late buds Bills Hotrod gift to me as he was dieing of cancer.
No there.

That leaves the Tall Deck BBC.
Longblock is rebuilt .030" over as we know from earlier this summer.
433 ci now.
Total I have in it is $100.00 when I bought in 1999.
Market value is low.
Even bare block Tall Deck 427 not sellling at $500 on fleabay or Craigslist Chicago.

i just was gifted a bare set of iron big block ford heads (d3ve casting) they arent the greatest option for big block ford performance but they were completely free and i am going to try my hand at porting them. finding a big block ford in a junkyard here is fairly common, so basically setting up a bi block ford test mule wouldnt be hard. a bottom end is $150 at the u-pick here locally... i think it could be built up on the cheap.

thanks for that info grumpy... i think im going to try to be real nice to an acquaintance of mine who has a flowbench and does alot of headwork and see if he will peak over my shoulder while i carve these heads up. ultimately any shortblock i sit these on will have an overbore, forged pistons and a set of rods all balanced to a factory crank to keep costs down. so the displacement wont be too radical unless something breaks and needs to be replaced with something better.
