Don’t buy, useless app. Will be pursuing a refund.

1:38 compression ratio... I don’t think so

I entered 302 specs at 4” bore 3” stroke and 8.206 deck height and it calculated at nearly 500hp and a 1:38 compression ratio..... yeah, this calculator is inaccurate, waste of money!!

I wish I could have landscape

That’s my only rub. And it’s not a big one.
