Wow, wish there was more like this post. Great note taking.

Impressive list.

Are you using an automotive air cleaner in place of a flame arrestor?

Are you using the K&N flame arrestor element with this?

[Wouter]

nope; just the air filter that came with the ford racing assembly. Motor box doesn't have insulation and gives just enough clearance (if that's why you are asking)

My thought was more to a backfire and the flammability of the paper element. My 69 Mustang with a tunnel ram backfired through the carbs once and melted down the low profile foam element air cleaners. Fire under the engine cover is never good.

[Wouter]

It's been on there for a while now but you're absolutely right... good catch, hadn't occurred to me

pix of the stang?

Any pics of the engine with the air cleaner? I would think that with an approved filter it would be acceptable to the Coast Guard.

[Wouter]

I see. Not coastguard approved unless it's the K&N Marine Approved per SAE J1928 Flame Arrestor Standard... No USCG over here: wonder if that's riskier in case of backfire? Myabe time to get the K&N one...
