Since I have (4) stg. II Buick alum. heads and feel they could breath freely, on a 4.1L block,(std. bore 3.965), can I put an "ood-fire" crank in there to get rid of even-fire rod off-set ? Destined for "unlimited class", short-course buggy. Off road cars tend to like the "gallup" for traction reasons. Much as I like alum., I choose not to spend $4k for a TA block. I think I got the clutch and mid engine, tranverse 5 spd,(manual) t-axle covered.Thanks, roverman.
