Hey guys im new around here and restoring an old kevlar 31 excalibur. The boat was set up for twin bigblocks and trs drives. Im staying bigblocks but converting to bravos. The transom is being filled so i can start over with x dimension. I will be running aluminum 496 exhaust manifolds. Drives are currently set on 33" apart. Does anyone know if twin 454s with 496 manifolds will fit 33"? I heard those manifolds sit wider then the old center riser manifolds. I am converting to offshore mounts and have to set the alignment from scratch so just trying to figure out where to start. Will 33" be ok or will i have to go to say 35"?

thanks for any insite or info!

i am running BBC with trs drives,,,i will measure the distance between drives. i am running stelling headers

they are very tight, i cant get my hand between headers.

I'm 36" with Gil manifolds and its tight but enough room for the hatch ram in between

Mine are 34.5". I wouldnt want to go any tighter than that.

I guess not as tight as I remember, maybe I'm just too big!

36" centers, tall deck, had to use Eickert / Lightning headers as the spacing was too tight for the Stainless Marine Gen III. Would love to go Stellings, but unsure they would fit. Go as wide as you can, 35"min, 36" if possible, your hands will thank you when changing plugs.

That's sexy!

At 33\" you can see i have no room for much! My 496 manifolds look wider then these kodiaks.
