we are going to pinelake today to do a comparison test with a 391 and the new ceo reverse dome piston.i will let you know what i find out.both are bdt ported engines with bdt pipes.so it should be a good test.

well what i can say is it is way more of a managable power delivery.powervalve need to be set just right.alittle less upper power compaired to the 391 but thats expected.really impressed with it so far.

That's awesome to hear. Did bdt port it or was ports left alone? I was wondering if it could be ported or if it should be left alone

I'm sure this is old news by now but I did hear of a 391 CEO from Arlen Being ported but due to lack of availability he's stopped selling ESR cylinders entirely I believe I ended up getting his last CEO Wich was a 350. I'm still confused what makes it a 363 is it just a stroker 350 or what. Mines setup a ESR 350 Wich uses a 86 style piston and cylinder height and I have a 88 crank in it with spacer plate. So is it then a 363 or is it a different cylinder set up entirely

i was testing it against my 363 and reg 391.and we switched to just running the ceo391.had a pipe made for it and it made all the difference.
