intake manifold
Searching around ebay and I say this...http://cgi.ebay.com/ebaymotors/CHEVY...spagenameZWDVW seem like a good buy to keep the stock BB hood on a 71? or seem like too risky?

I got news for you. That thing isn't going to fit under the stock hood anyway. Edelbrock makes one manifold that will fit under the stock C3 hood.

This is the only dual plane, spread bore, aluminum intake manifold I know of that will fit under the stock Big Block C3 hood. They were used on the '68 and '69 L36 390 horse 427's.

Re the uneven ports in the Performer on Ebay, the Torker II Oval also has uneven ports like that. The discontinued Holley Street dominator oval port manifold will also fit under the stock BB hood.

Holley street Dom?
Hmm, well I have heard both!! 
Some have said that the Holley will fit others say that it will NOT fit. I guess I am just going to have to buy one. I do have a L-36 on the shelf just in case. I would like to hear if anyone has had good experience with the Street Dominator making power in a mild 454 or a more radical 454.... 
I need to swap and tink with the old girl. Usually the Holley intake can be had for ~ $100 on ebay.

Hi. This is a little off-point, but does anyone have experince with the Edelbrock 2 x 4 manifold? I am about to begin to build a 540 inch bigblock for my '75. It will have rectangular port chevy heads and I have been looking at the EB Performer-RPM cam and the 2 x 4 manifold.

Is there and draw backs to using drop downs?

Edit: You may want to purchase a banjo fitting for you carb. The straight out type gas lines can interfere.
