Will try to, the person doing it is very thorough and I think my results will be much different this time, or at least right, really wish I went this route last time, buddy said if I can find a way to fit a spacer I should, worth a good 10 hp in every case he's seen... Gotta see if I can find space for it... New challenge lol

I don't know why you wouldn't.

You're gonna want to get on it. Dale is busy and your stuff gets worked on in the order it comes in no matter who you are.
I'd have him go through the both carbs and ensure ithey are what ithey are supposed to be. Just like the heads, it's not unheard of for parts to be assembled incorrectly or with the wrong parts.

I had a couple ideas from looking at your bildge pics to gain some clearance... I would make a top pan for your arrestor but i would recess the top of the pan in the center so the top of the nut is even with the top of the pan. It would have a cup so to speak. Also trim some height out of the mesh in the arrestor. And lastly. If the bottom pan has a lip on it so it sits of the top of the carb make a flat bottom pan for it. With all that you could end up with an inch or two. We have a good machinist that custom makes us tops and bottoms on a Bridgeport. He actually has a table the he uses to but a nice raidused lip in the pans. Where there is a will there is a way...

A guy or two over at http://racingfuelsystems.myfunforum.org may know already. If not, by bore size, venturi size, base plate, and booster.

What you mean on top pan? Lost there lol

That being said about the mesh, I figure 3" is pushing it so I did t want to shorten it, wonder if anyone has flowed 3" vs 2" let's say... Hmm can't see it flowing enough but maybe? If I can go 2" I can add a 1" spacer

Such is life. Try building a boat from a bare hull with a 1 1/2 and a3 1/2 year old running around the shop.

On a side note.....we are all going to the track Friday night to blow off some steam and see if we can break our cars. You should blow the dust off the cobra and join us.
Give it some thought, be good to clear your head and burn some rubber!
