AFR shows five builds on their dyno website. Check 'em out.......

Look at the fifth build down.
Over 450 lbs. of torque at 2,500 rpm's.
Over 500 hp at 5,500 rpm's.
All this on pump gas and less than 10 to 1 for a comp. ratio.
This is what ever sbc guy needs.
This is as close to perfect for a street rod or muscle as you will ever get I.M.O.
