K cam has a useful power band from 2000 rpm to 6500 rpm. So, not that great of a match for below 5K rpm acceleration. Also helps to have more displacement than 2.1 liters with the K, which is why the Penta engine that got the K cam was the AQ145, which was based on the B23E, but with dual carbs.

Personally, I'd swap the A in the B230F out for the B that's in the now-B21A engine. Drop the A cam into the B21A.

1982 242Ti - black, M46. 1985 245Ti - blue, M46 - soon to be for sale.
