I find a suprising number of 2.6 Ks. Last year, visiting sellers, I drove a number of LeBarons with smooth running 2.6s. All of them are slow from a start, in other words, no kick, but get up to 75 no problem.
Jonah's 81 Reliant is the most smooth running next to last surviving 81 mitsu I every saw and drove. The other 81 2.6 mitsu I drove ran like crap.
