Air Filter advice

[rzayas66]

I installed a Chevy V6 60 degree from an 83 S-10 and a Camaro T-5 5 speed in my 79 MGB. Got it all in and it seems to work fine (can't really test too much until the exhaust is installed tomorrow). Used the Classic Conversion kit and some parts from BMC (thanks to Bill and Brian, respectively, for their enormous help and products).

Plan on doing the finishing touches this weekend and have a question:

I have the stock S10 carburetor (Rochester) in there and I need to devise something for the air filter. Bill recommended a modified hood but I just had my MGB painted a couple of months ago and would like to avoid that expense if possible. Any options on building/buying one low profile air filter assembly that might work? I also have a Holley Carb and manifold I was planning on putting in, but that seems higher than the stock one.

At this point, if I must buy the hood, I must, but an option would allow me to save some money.

Thank you,
Ron

How much too tall are you?  If the Rochester has a standard size flange, you can use a drop base.  They come in various diameters & drop amounts.  I've seen 14" ones with as much as a 2" drop.  With a 3" filter you'd only need about 1 1/2 or a little less over the carb to clear the hood.  You could also use less drop & a 2" air filter -- just be sure you allow enough room for the choke to open & air to get into the carb throat.

Here are some examples at Summit Racing.  Jegs & Speedway Motors have some of the same & some different ones.  http://www.summitracing.com/search/Department/Air-Fuel-Delivery/?keyword=drop+base

Edit:[/I]  Come to think of it, even if the Rochester doesn't have a standard size flange you could still probably use one of these by modifying -- just graft in the flang from a filter base designed for the Rochester.

Rob:

good advice. i will do some measuring and then checkout the summit racing options.

Thank you!

One quick way to find out how much room you have over your carb is to put something flat/thin on top of it & then put a ball of playdough or silly putty or something similar on top of that (about where the cross piece is on the hood) & then close the hood.  It'll flatten the ball out & when you open the hood you can measure how thick the flattened ball is & that's how much room you have to work with.
