Reply to "Upgrading from 1776 to 2110?"

My suggestion: Change out the cylinders to 94mm.

Get the barrel bases machined down to the 90.5/92mm register size. You can do this, I'm building a 2276(94 x 82) this way that was a 2213(90.5 x 86 stroke). The barrel bases are thin, and can easily be cracked so be careful.

You'll have to get the heads opened up for 94mm but no big deal. I think a 1915(94 x 69) with the cam, rockers, exhaust, and TBs you have would be right at the limit of your exhaust. 120-125 hp, and a NICE upgrade. You probably don't even have to split the case if you do it my way...

A 2110 would probably get choked by that exhaust. But if you must keep it, build a 1915. The cylinders(Mahle please not AA) will easily last 40,000 miles. Is that enough longevity for you?
