Plate in riser of 496 manifolds...
 

Are these needed for sure? they look small, I thought I read they are not that critical, I want to see if I should run them or not..

take them out you'll be fine, i did it to mine and the motor runs a little better

anyone have some turbulators they are not using? Need a set for a low performance cruiser 454 using the 496 manifolds.

I had 2 sets will check when I get home on Friday just sned me a pm to remind me. If I have them they are yours just pay shipping

Take them out. Makes it sound like a 500. Added 1 mph to my boat.

Arn't they in there to stop reversion?

I still have mine. Took them out this winter when the whipple was put on. There yours if you want then.

like above, took mine out and sounded better and picked up about 100 rpm's

as a non paying cheapo member I can't PM...:party-smiley-004:

GoFastSonic or I DIG IT !! if you could contact me via E-mail [email protected] thanks!

Also, I read here that they are 'probably' there to help catch any condensation drip more than to combat reversion.

I ended up leaving them in for now, iw as told they are for condensation like staed above, I may experiment this summer, I will remove them and see if any gains happen if not I wiill put them back in to be safe, thanks for all the help!!
