World Products Single Plain Motown Manifold

[Quarter Flash]

Has anyone seen a dyno test on this manifold? How does it do with a 406 size engine? I bought an engine with this manifold on it. I have a 4600 stall, glide, 600 lift, 255 duration, solid roller, Dart Pro 1 215, 10 to 1 compression. Car will weigh 2600 to 2700 lbs. My thinking is the manifold will not pull on top well enough to get me to 6500. With my stall I need upper end performance. I have not been able to find any real comparrison information on this manifold

Bob,

I haven't seen any tests on one. I considered buying one when I built my motor but I went with the RPM Air Gap since I am street oriented. I would think since you've already got it you could use it and if it didn't work maybe go for a Victor or maybe even a tunnel ram...

I think it would work fine myself. Bill Mitchell puts it on his 427 and 454 crate engines and they make 550 and 600 horsepower respectively.

havent' seen it dynoed, but it looks exactly like the weiand team G on my big block, which is good for 2500 - 7900 rpm. If you need a little more on top end, try a 1 or 2 inch carb spacer with the open center. Not the ones with 4 divided holes - they work for lower rpm's.

If it's the one i'm thinking of ,it's a nock off of the super victor.It's a good manifold for a 400+ cuber.

Thank you for your replies. Here is a pic of the manifold.

Just make sure you run the right intake gaskets. Fel Pro 1206. The intake is a very good piece, but like all others, may need a little work to port match it to the heads.

Am I looking at annular boosters in that carb?

[Quarter Flash]

I did port match and use the 1206 gaskets.

your right on the carb

Thanks I had never seen one of these manifolds before.

Bob,

That looks like a lotta horsepower just sitting there!!! It will look sweet in the engine bay...

Have fun!!

I have been taking pics throughout the project. When I have time I will upload some of them. As I said before this is a ground up drag car using the Jeg's chassis kit. My computer software guestimates I have about 550 hp and 500 pft over 1300 rpm.

the highest I've taken this combo is 8 grand but she still pulling hard just not a strong enuff bottom end to take a big block higher my 02 is the carb needs to be 4500 series thats what made mine come alive

Nice car!! What does it run in quarter, MPH and aprox engine power? How much does your Vega weigh? I am so curious to know what my Monza will weigh when I get it done. I guess I keep working on it until I can weigh it. My engine broke 550 hp and 500 tq on the engine dyno so I know it wont be a pooch. I figure anything below 11.0 is good.

the car weighs 2650 w/ driver 190 lbs driver 496 bbc dyno at 693 hp651 lbs we were running the 1/8 5.80 class with too much gear in the car to slow down to a 5.80 the 5.80 class is the hardest class around here so thats why we are taken weight out of the car now beefing up the chassis (7.50 cert) adding more power tunnel ram two doms new cam port work by yours truely looking for over 1,000 hp and we are gonna start running the texas pro stock class low 5's to high 4's in the 1/8 high 7's to low 8's in the 1/4 we will most likely have to wait til I can afford a new short block to be compepitive but if we can click off some low 5 passes I'll be happy thats without NOS all throttle no bottle
the 693 hp was with stock heads and no vaccum pump as you can see we added al heads an a vaccum pump since then but kept it in the 5.80 class

[DDBBCVEGA]

as a guess bob you should click off a low to mid 10 seconds with all things working right

[Quarter Flash]

That is what I'm hoping for

Thank you
