Super Jet 62T with 84mm wiseco

[boostedmax]

I recently got a sn superjet and had a couple of questions on my motor

62T cylinder and cases,64x intake manifold with dual 38mm carbs,61X stator, flywheel and ebox,wiseco 84mm pistons (757M08400)

Should I be concerned about it being 84mm?

should I run dual cooling?

what should I start tuning the carbs at?

64x manifold takes oem 44s only, 62t manifold takes oem 38s only. Look at top of carbs, 38s have 3 bolt tops and 44s have 4 bolt tops.

My mistake it has dual 44's

guess that changes all my settings
