I've got some 1/4" aluminum plate here that I'm cutting up.  I can trace out a cover for you from a new gasket I've got and then you could trim it to fit the way you want it to.  I've got a 460.

really? thats kick ass!...you mean you'd send me some metal w/ the trace on it? shit how much do you want?....i cant find one anywhere.

How soon do you need it?  Traced???  Hell no, cut out and the holes drilled. Whatever the postage is is all I'd ask.

not super soon, im just going to mount the bottom part of the TR as soon as i get it back next week...but i wont need one for about 2 more weeks...take yer time, and thank you, ill totally hook you up w/ whatever you want, its really appreciated!

okay, that sounds good, so they're not DP's? i think i have another pic of the other side w/ all the action on it...ill post it up soon...thanx for your help bud.

Reid

Technically no, but they are based on the DP carbs and have 1:1 ratio (pri and sec open together), and the acc pump shoots from the center rather than the side. These are race carbs typically, and designed for a 2x4 application. They are good carbs. Most people would still consider them double pumpers...

I've got a question, if you block off the thermostat outlet, how do you keep the top end of your motor cooled off?  I'll have that plate laid out and ready to cut tomorrow, if the wind and rain let up. 

Yes the heater hose outlets are under the thermostat housing.  I just tapped and plugged one, and the other came tapped.  My old manifold I clamped a rubber end over the untapped outlet and it eventually broke, blew off and almost sunk me, twice...

Those carbs could also be 450cfm 9776's with 50cc pumps.  But its hard to tell from the pic.  the 9776's are a stripped down inexpencive version of a 4160 style carb with mechanical secondaries but only one accelorator pump (not center squirters).  Designed for 2 x 4 applications only, decent for the price but the 660's definetly are the hot ticket.

BTW Glenwood makes that block off plate, but it looks like Gregs got ya taken care of.  -Later

glenwood eh? is there a web site? id sure like to let greg off the hook, but hell, if i cant find it at a shop like team C or any others online, shit how am i supposed to find it? thanx for the info, ill look them up!

I agree (I originally thought that too - I have a pair of those 450's on my tunnel ram), but that 50 cc pump made me think otherwise. The 450's (and the 390's for that matter) have such a small verturi bore that the secondary pump is unnessasary. If the pump was bumped to 50cc, it would probably only run right on a really small ci engine (that really over carbed)  - as you would have major bogging out of the hole. That was my thought anyway.

A pic of the other side would really help (the secondary linkage is a tail tell sign) - one without the scoop would be the nail in the coffin. They are probably one of these carbs:

390 mech secondary
450 mech secondary
660 center squirter

The 850 center squirter comes with cathedral bowls so we can eliminate that. 

1:1 Linkage on pri/sec - no acc pump linkage on secondaries - 50 cc pump - non cathedral bowls - definately a 660 center squirter carb in my opinion.

Will the fuel pressure be the same in the second carb with that set up or should there be a pressure regulator with 2 outlets?

I bought the Holley Marine fuel pump kit and it comes with a regulator that is set up for either one or two carbs.  So I would think that it would take care of getting the proper fuel pressure to each carb.  It also had a plug so if you were only running one carb you could block off that outlet.  It is bottom fed.
