i've always like the edelbrocks. my brother and I are building a gt40 iron powered engine, and he may go with the edlebrock knockoff, typhoon for cheap and port the **** out of it.

from what I understand the cobra is kinda old now, and not the best buy for performance, and I don't know too much about the trick flow.

the cobra isn't bad but if you already have the street heat you will be better off. I ran the edelbrock performer intake on my old ported gt40s.

Which intake is best is not always easy to tell. Take a look at this dyno test comparison - the higher curves are using a stock Explorer intake and the lower curves are a Track Heat. Car had TW heads, AFM N-41 cam, shorty headers, 65mm TB, 73mm MAF.

HP (2,000-5,600 rpm): Explorer - 204RWHP average & 301 peak
Track Heat - 195RWHP average & 275 peak
TQ (2,000-5,600 rpm): Explorer - 276RWTQ average & 303 peak
Track Heat - 264RWTQ average & 307 peak

yep.

i say neither. get the RPM intake and be done with it. then get a 70mm t-body and a 75mm MAF to match. throw on a set of 1.7 rockers with the stock cam and dont sweat it too much.

I believe he charges the same amount as that he charges to do the E7's which is $595 I believe.
