I can't decide on an intake manifold i have a SBC 400 with a solid roller cam 4000-7600 a set of the new 215 dart pro 1's and a 850 demon i'd just be quick to say use a vic jr but is there a better intake? under 500 i know theres some CNC intakes out there.

The 2975 Victor Jr. is a good manifold for a 400 with good heads. Your power band should be right were the Victor makes power. You could look into the Weiand Team G series too. These intakes have slightly less plenum volume then the Victor and Super Victor. You might not have to rev your 400 quite so high. Plus the smaller plenum volume could help make more power down low for the launch, without sacrificing top end. Of course with a 400, your going to have nice mid range anyway. Just a thought.... :D

i experimented on a mild 406 with a victor jr and a super victor .. the super victor was by far the best out of the two it would drop from a 1.56 60 foot to a 1.62 but ran 11.60 compared to the 11.73 or the victro jr.. but when i added a 950 hp vacuum secondary it ran 11.40 best . i sold the super victor to try a torklink custom intake and it sucked and i went back to the vic jr because i sold the super and didnt have the cash to buy a super again . then sold car ... but good luck on what evr you decide.

Try one of the 360 intakes 8) http://store.summitracing.com/egnsearch.asp?N=700+400429+307657+115+4294908216&autoview=sku

360 intakes don't have isolated runners. an all out victor sounds like it hurts the 60 ft and thats why i went with 215 runners instead of 230. don't know where you found a 950 cfm vac sec i thought the biggest made was demon's 850 with annular boosters like i have.

timmy the super victor is the intake to use or the brodix the reg victor not enough intake. i have been doing this for lots of yrs and the engine that your building is fine with super vic. i had a 406 in a chevelle pump gas small roller and it made well over 500hp& 500ftq and went 11.30 with the super vic. it's not that much bigger then the reg victor it's tall with better intake runners. there is no way a reg victor will out perform the super on a 400 or larger small block.

the ports on the super vic are to big at the head i'd have to gasket match my heads before i could use that intake. the new darts have been wet tested i don't know if i should mess with them

The Brodix HV1000 intake ports come small so you can match port them to your cylinder heads .They work quite well.

like bowtie and i said use the hv 1000 then but i think the super is matched to a 1205 gasket and the dart 210 are the same. i could be wroung then use the brodix intake. the reg victor intake doesn't work all that well behind 400+ engines. i wouldn't use a vac sec carb either. what size cam is the motor running? the flow numbers for the heads?

i liked the super better. it will pobably 60 foot as good with some tuning. but i bought my 950 vacuum the first years i saw the hp series show up in speedwaymotors.com i tried a 950 dbl and slowed a tenth in qt but i didnt try tuning . it could be that a 950 dbl was too much but a 950 vacuum was good . maybe it would of liked a 850.

I think i'll go with the super victor and i'm gonna send my carb back to jegs since i only bought it last october they'll give me a refund and i'm either gonna buy pt# 778-67200 or 510-o-9379 and i'm gonna return teh wilsons spacer since it won't work on anything smaller than a 850 anyway.

got the super victor intake and bolted it on the heads I'll never buy a edelbrock intake again i think you get what you pay for if you want a nice race quality intake spend over 380 bucks get a nice one. the dividers are a little off center and the ports are to wide in some places. i once bought a trick flow intake for a 302 with afr heads and the ports lined up perfect no porting at all necessary

Sounds like the mold shifted and they just kept on casting, thats the problem with mass produced stuff their QC isnt all that good from time to time, I'd send it back and get my money back and go with a brodix hv 1000 or the dart pro 1 myself, they dont make nearly as many as ole Vic does so the QC ought to be way better.

I did a intake test on track a few years ago. Motor was a 434 SBC afr 227's with work, 670lift roller cam, eagle insides with je 14:1 comp. 950 apd alky carb.
I started with a out of the box pro-products intake that I just gasket matched here in the garage- I paid $150.00 i think for the intake new off ebay-
I then went to a super victor out of the box
and the last one I tried was a dart wilson out of the box.

Much to my suprise the cheap intake was worth a lot of et/mph over the super victor over a tenth was gained with the pro products over the SV intake. But like mentioned above you get what you pay for, the dart wilson was very clean nice intake for being out of the box, and it was another .05 faster then the pro products intake.

On my big block I baught a super victor tall deck, worst intake I've ever seen. My motor builder said the samething, it looked like mountains were growing inside it with all the extra metal.

I run the Super Victor port matched to AFR 227's with Holley HP1000 on a 409 cid SBC with a .630 roller. This is in a 3500 lb car w/driver running mid 1.30 - 60 ft. times and easy low 10's @ 130 plus 1/4 mile. Used to run the Vic Jr. and was just not enough on the big end.

Of course I never buy an off the shelf intake or heads without expecting to do some kind of port work. :)
