loose

They do fit loose. They are designed to get the flow moving in the spiral once that happens it will act like a funnel and increase flow.If the baffles fit to tight they can raddle or even make a tone on the side tube. Don't forget you can change the the flow by drilling a hole in the cap. The more horses you have the bigger hole. I have 425hp with a 7/16 holes drilled.

I got them for my 427 sbc, wasn't planning on drilling them out innitially, but maybe I should? It has a 670 lift solid roller in it, think I need to?

I drilled mine out to a 7/8 inch hole. Feels smoother than before during exceleration, and the sound is even better than before. Caught the itch, thinking about making them even bigger.

I've done that, but between shifts the rpms drop off far too fast for my liking. The sound was incredible though.:devil:

You can always put a new cap on if you don't like it. They are just tac welded on and you can get the cap at any auto parts store just size up a freeze plug.

Mine slid right in. Not to tight but not loose enough to where they hung. After installing the allen screws they fit perfect with no rattles. I to am contemplating drilling the cap but My side tubes are stuck tight to the headers pipes. Any tips to getting these things off????

thanks

Pound on one of the mounting tabs from underneith with a 2x4 block of wood and a 3# hammer. Spread open the clamp with a screw driver. Also use mucho amounts of penatrating oil for a couple days prior to the hammer.

Try a little bit of heat from a butane torch. Just on the side tube, not the header.

BAD IDEA...it wil change the colour of the chrome :spanked:
ehh? I said a little bit of heat, heating the side tube slightly with a butane torch isnt going to get any hotter than engine exhaust gasses. Heat it just enough to expand the collar of the tube.
