intake?
I can't seem to ever get an answer when I posted before, so I figured I'd give it one more shot. Is there any way an aftermarket intake manifold can fit on my 71 big block; be it through drop base air cleaner or whatever? or do I have to have an L88 hood at minimum for one to fit? If there are any what are they and are they any good?

I'm sure there is an after market intake that will fit your big block. Find the one's you are interested in and look them up on the internet or see your local performance shop.

You can usually find them on E-Bay, but they may be a bit pricey.

It's basically stock, so its oval port. The only ones I really know of are Edelbrock and the such and most of them seem to say will not fit under stock hood of corvette, but I seem to remember other posts bout someone being able to do it, but it was always either another year or a small block, so I was just looking for anyone who had tried it.

I think I have seen where other members have gotten the Edelprock Performer series to fit with drop downs....seems like the wing nut will just rub the hood insulation. RPM air will not fit - not even close. This was debated several times in the last year...search may turn something up. Most manufactures give you, or can give you the dimensions of the manifold and how to measure with your current hood to see if they fit...

I seem to remember also that the old style Edelbrock Torker manifold would also clear the hood. Heres a pic of one off E-Bay. They usually sell for pretty cheap.

The Edelbrock Performer will let you lose weight and run a little cooler. For the price, the performance gain is minimal. It would all be low end gain (under 4500RPM)
The Torker is probably best if you have a stick shift and a warmed up engine. Power gains would be more noticeable in mid to high RPM range (2500-6000).
Performer is more "street". Torker is more street/strip.

I have seen a few bb's using the Torker Tarantula - an awsome looking piece.

I do have a stick shift, and a warmed up engine is definately not a problem in this South Carolina heat...but the torker being a single plane manifold wouldn't i lose a lot of low end throttle response and power? Also would the torker 2 fit under the hood if the torker 1 does? Would this be a better manifold?

soccer794: Oops....by "warmed up" I meant with a cam and headers, etc. 
You can keep low end throttle response by using a Holley double pumper carb around 600-650 CFM.
Torker 2 I'm not sure about fit. Have to ask one of the other guys.

I did a lot of research on this topic for my 71 BB
Your oval port choices are:
1. Stock Cast Iron LS5
2. Aluminum L36 ($$$ on ebay)
3. TorkerII - will lose low end
4. Discontinued Holley Street Dominator (single plane but raded from idle to 5500)
I went with #4 because it was cheap, aluminum, and rated better than the Torker. Could not be any happier with the results although I did have to mill my choke tower and get a 2.25" air cleaner. This all barely fits under the stock BB hood..

I'm in the process of getting hooker 1-7/8 headers and it already has a cam, but i don't know the specs cause the previous owner put it in, but its pretty mild. Thats why I'm looking into an intake get more air in and more air out and hopefully soon get a more agressive cam. Any idea to about how much low end i would lose vs how much i would gain up top? Big question I guess is will I still be able to explode off the line at a stop light and put that dinky mustang next to me to shame?

For the double pumper would 600-650 cfm really be big enough? Holley's website seems to recomend something more in the 700-800 cfm range. http://www.holley.com/HiOctn/TechSer...nfo/P225A.html What'd you think?

I'm getting the 1-7/8. http://store.summitracing.com/defaul...earchType=Make
I've been told that going bigger will lose too much low end and I heard they fit perfectly from some and that you have to dimple some of the tubes from others. Those are the ceramic coated ones, non ceramic coated are about $100 cheaper. Not really raining much here today did a llittle earlier just really cloady right now, but still enough to keep the vette garaged
