I’d run it at 5 lbs you should be good for a street car , I wouldn’t beat on it much. I assume you have a stout bottom end , cross bolt , forged crank ? I run a boss 540 ,14-71 on e85 on the street and m5 at the track . Like you’ve read test test test !!! See how consistent it is per fuel up. Up here in Nd they start switching over to summer blend in april still 2.29 gal at cum and go Very consistent.

Well it gets lonely up here in the oil patch , what you don’t have a gumare ? Lol  no no no been with the same women for 15 years up here . No tepe creeping for me. So no pics of a front motor plate ? We ant to do it rite the first time not pull threads all out of a $7k block . That’s wye I asked about how thick the timing cover backplate is, maybe weld some ears to it . Any ideals are welcome.

Ya I wasn’t sure on manifold for water , but that’s a lot better than having to pull it out back of heads. Now just have to find one , with him not making any more . As for burst panel I’ll have to see if I can pick up a mount from McAmis and fab it into the back of manifold above the runners. Then fab up a fork style chimney . One on each side of blower. I plan on running dominator efi with msd pro 600 I’ll just have make up some brackets for coils and mount them to the blower mount studs. The ones you made up are sweet . As for bore size that’s what I was thinking about 4.375 just wasn’t sure with only having little over 1/4” between bores, that’s why I was thinking offset boring to get a little more space. To bad Shelby didn’t make a compacted graffite block. I’m new to the sohc so any help is nice. One more thing? How thick is timing cover back plate ? Need to figure out a front motor plate and a crank support if possible. Pics of some ? 40 % od is a lot with nothing on front.
