I've heard so many conflicting stories I just wanted some of the GURU'S to voice what you know from actual dyno experience. Some say that domes interfere with flame travel making them a bad choice that flattops are the only way to go, some say thats bullsh#%. Give us you're opinion! Thanks:confused:

I heard the same thing years ago. When I built my 572 I stayed flat top and milled my heads to get the compression up. Lem tells me now that the A heads dont mind a small dome so my new pistons have a small one. Probably has something to do with the combustion chamber as well.

Sometimes big domes on an Ugly girl can be fixed with beer goggles. Alky won't help with the other deal. :)
Big domes, and flat head is a good combo......got somewhere to set peanuts and beverage.
Add quarter slot and a pistol grip ear shifter (folds back 'intake strainers'), combine with beer goggles and throw a flag over the flat top and all is good!!!!

The domes I spoke of are only .215" tall and a good smooth shape . Tall and ugly is a different matter ;-} .





From an engine I was given for helping a guy out. 480" cubic inch limit ( 4.375 x 3.98 ) w/ a Bryant billet crank w 2.100" rod journals BME alumi rods . A-460 heads w/ 70 cc chambers 15:1+ on alcohol.

My new babies for the 565"



13:1 with a 66cc chamber A-460's.

If the question is" "Will a motor make more power with perfect flame propagation than it with with the correct compression?"....put the dome on it and go racing.
Gotcha, I personnaly don't like them for more reasons than one, flame travel being one, weight being another! but was listening to some guy's arguing about them at an engine builders the other day and just wanted ya'lls opinion of them! As for where the post went, enough WILD TURKEY will cover up a whole lotta UGLY! and after about 15 minutes I don't wanna see her again anyway!
