Good to go. You can build the engine from scratch if you want.

Thanks for the input.  Now I need to decide on the body or team up.

If you are building the engine that close to the class limit and don`t get it sealed prior to the event, bear in mind that you may have to tear it down if/when it gets a record to verify displacement the old fashioned way...so plan accordingly when packaging....

I'm down with that.  I may tweak the bore/stroke to yield 182.96ci if testing shows a head flow increase.  I imagine that is still too close to the mark for a mulligan.  Thank you for that insight.

I was originally focused on some coupe body class, but now I'm thinking lakester, modified roadster or other non-coupe class.  Decisions, decisions.

In addition to ease of certification at the track, perhaps a more important issue is that there is no room for a clean up hone with freshening the engine. I have that issue with an engine that is within 1" of the limit. Everything is custom anyway so is not an issue of finding stock parts to fit but .005" hone would put me over the class limit. Give up an inch or two for the future.

An engine that close to the top of the class will have to have the head pulled at any Bonneville race before we go home to certify the record. Bear in mind if the rain comes hard enough on Wed. to shutdown the meet you and I will have to stand outside in the rain and wind to get your 3 liter record.
