Your question is a little wide spec. Considering this to be a run all day engine...
Based on a GM Mark 4-5-6 type block...
600 or so tops normally aspirated.
upwards of 850 with some form of PSI maker.
Any more than that and you will need a custom block. I would need a home equity line of credit.
That Teague 800 is a real special piece for sho.
