Does anyone know the difference between a Weiand X-Celerator 7510 and the Weiand 7510? This is for a 340. I see a basic 7510 just has one post for the coil mount and the X-Celerator has two but is there a performance difference or RPM difference etc...
Thanks Ron

I was thinking the small block Weiand X-cellerator intake was a 7545. I know cuz I've been looking for a cheap used one for quite awhile to no avail. class rules require it

I don't know about that, I'm looking at 2 different ones and both say 7510 on them but one also has X-celerator and the extra coil mount.

OK Super Bowl is over anyone????

There is two on the bag, one is 7545 and the other is 7510. I have one in the shop, I'll check it out later. Very good intake IMO.

Would this be a good street car manifold?
I'm reading mixed reviews. Say a 340 from 8.5 -10.1 compression.
Dougs D453 headers and a 650 DP in a 4 speed A-body with 3.55-3.91 gears.

Cam is up in the air also, thoughts are Hemi Grind 474 lift or maybe the Speed Pro CS1019R 443-465lift.

Engine isn't opened yet so don't know what compression or head is on it.
There isn't a J or X by the sparkplug area just what looks like two vertical lines ||.

An educated guess:
The 7510 was a mid-to-late '70s answer to the Edelbrock Torker. Edelbrock's Tarantula started the move to X-type single plane intakes. The Torker was their street version, made for a lower rpm range. The other intake manufacturers followed suit as the X-type was sweeping the nation. I was building a street 350 for a chevelle at the time and I bought a Weiand 7504, which was their version of the Torker for sbc. I used a 221@ 50 lift camshaft and a 600cfm Holley and it ran good and got nice gas mileage, like 19 or 20. I remember the intake as being quite tall.

Weiand would add or change nomenclature to intakes to change with the times. That's where the name X-celerator came from. X-type intake made for acceleration. I would think that the outside part of the casting was all that was changed, the runners are probably identical. When runners changed, Weiand would change the model number.

So they function equally well, would be an okay choice for high performance street, although maybe not quite as good as a Torker 340, but the two brands tended to be quite equivalent on power back in the day.

I ran mine on a 340 that was 11.3-1 with ported Edelbrocks, a Hughes 237/242 hydraulic cam with 3.91 gears and a 28" tall tire. It worked very well. IMO it's a better intake than a torker.

Once you figure your heads out and decide on the intake call Hughes Engines for a cam. They will want to know everything about your combo and it's intended use.

Here's the manifold I'm thinking of buying:

Here's the one that says 7510 X-celerator:

Yes the Performer RPM does look like a good choice with the dual plane plenum.

That manifold had better paint than some cars!!

I have a Edelbrock Torker 2 intake that looks almost identical to that Weiand intake,#5076, its rpm range is 2500-6500. I was selling for $150 shipped in the lower 48, just had it bead blasted,no port work done,no stripped holes etc.
The Edelbrock site says the carb pad height is 5.25" at the front and 6.19" at the rear of the pad.
Didn't mean to hi-jack,figured I'd throw it out there in case you're interested.

IMCA class rules only allow a 7545. I have a torker 2 that looks almost identical & they said no
