Choosing a Manifold:SBF
 

I need to pick a manifold to slip between a 600 cfm Holley (This Carb) and a 302 Ford in a 68 Mustang coupe. Holley and Weiland are from the same company, so I thought the Stealth would be a good match, but the Edelbrock Air Gap RPM is well reviewed, too. Both are about the same height, so fitment would be the same. It will be a 1/4 mile drag car that is street legal and must see about 40 miles of highway time to get to the track until I can afford a trailer.

Thanks.

Dale…How much cam, convertor, rear end ratio? Based on your description, I'd go with the Edelbrock RPM. It has a broad RPM operating range and the respond well to carb spacers for additional plenum volume. They make excellent Torque being a dual plane. They work great out of the box. MB.

we stock sell and use a lot of the Wieand 8020 Stealth 180* high rise intakes along with most of the other popular aftrmarket SBF intakes. FYI the Edelbrock Performer is a stone makes zero power over a stock cast iron FoMoCo 4V intake
We have found it to work the best for most mild street applications It is a virtual duplicate of the old Ford muscle parts C90X intake which was the best ever street intake for a SBF and very similar to the Shelby GT-350 high rise intake and it accomodates most any 4150 or 4160 Holley and Autolite/Motorcraft 4 barrel carb. Another plus is that even with a stock air cleaner they'll still fit under most any hood. 219-861-1214 Days OR monymkrssla@aol.com anytime

Alex: Good to hear from you. Do you mean the Weiland is comparable to the aluminum manifold Shelby used for the 68 recall that finally put a good carb on a 302?

Dale…RPM AirGap. Is your engine internally balanced? MB.

Re: Choosing a Manifold:SBF
 

Yes. Eagle crank, Crower rods Keith Black dome pistons. Going to run bracket this year and switch to flat top pistons to get legal in GT for the future.

Re: Choosing a Manifold:SBF
 

Edelbrock Performer and Edelbrock RPM Air-Gap are 2 different intakes. Dale, your engine sounds like much more than a mild street application,, certainly wilder than the 302s built back in the day. With your setup designed for more rpm, cam wise and converter wise, I'd go with the Air-Gap,,, but its your choice, of course. Take care.
