If anyone has built one I would like to hear about engine builders, recommendations, issues, things you learned as you went...etc

Many thanks
I'm running about 350+ hp with big, wide sticky tires & it's pretty manageable. You'll get a lot of varying replies. You'll have a lot less tire on the ground with a slab. I personally think 380 would be a lot, if you aren't cautious behind the wheel.

350 HP in a street roadster is plenty! And for sure you want the .82 with a 3.31. The .64 would be OK with 3.77s or shorter.

FYI we have a customer who put Blockley 205/70x15 tires on his 289 and loves them. very "period" like the Pirellis or Michelins available in the day.
