Multiple Carb Question

[Cobrabill]

Dove is a four letter word.
Moving on.......There are way too many people that think intake ports that can swallow a tennis ball are the ticket to power/going fast.
The TP was designed for NASCAR competition.And compete it did.It actually kept up with the Hemi's on short tracks.In the late 60's Pontiac stole the TP design and called it the Ram-Air V.It never made it into a production car as street performance was abysmal.
Velocity is the key in filling the cylinders at lower(street RPMs)speeds.You don't get that with ports you can stick your hand down and feel the carbon build up on the valve stems.

There are always exceptions but in general TP's ain't a good idea for the street.

I run a TP in my car and let me say that it's giving me plenty of performance. I had to do a bit of work to get it running right but now that it is, it's totally awesome. I changed the pistons from 12:5:1 to 10:1 and put in a Crane cam 579-605 lift 280-290 duration. Although I have had MANY manifolds for it, I'm now running a single 4 with a Holley 780 DP on it. Due to the flow of the engine I had to increase the jet size 4 times but the results have been well worth it. The car is at Cobra Automotive right now and I'm going to see if they can put it on a chassis dyno to see where it's at HP wise. The last time they had it there they also had a Kirkam in the shop that they had installed twin turbo's on. They said in their opinion that my TP was just about as much motor as that twin turbo so I think that about says enough...lol. AND, it looks totally awesome too. I'll update my pics in about a week when I get the car back for anyone that's interested in TP pics. Anyhow, that's just my humble opinion of the TP, it's working very nicely for me and I find it to be pretty streetable.

I'm thinking if 6 duces are good an 4 quads are better I might want 8 quads.. Would I stll be able to Idle below 900 rpm?
