I just took delivery of the cheap speedmaster single plane manifold and at first glance it looks pretty good,for $98 new im gunna take a gamble on it,also comes with intake gaskets,and looks pretty much like the weiand accelerator 2v,also has undrilled bosses in the runners to put NOZ or injection ???.i expect to clean it up inside with the dremel drill so i will sus it out.

decent packaging

Looks good mate, let us know how it works out

What do the ports look like?

 

I think i saw one of these somewhere previously and all the ports were irregular sizing.

[xwagon 168]

gasket looks pretty big, do you have 4v heads?

[gerg 10,871]

It's basically Pro Comp. The runners being different lengths can't be good at high rpm. I've read some horror stories regarding the machining of heads and manifolds so double check the alignment when you fit it, also port matching as Hendix mentioned.

Like i said it was so cheap its good to have something to play with,i also bought a set of 1-3/4 headers off them about 6 months ago for my clevo in the xe and noticed that the felpro 2v gaskets didnt match all that well,they do supply their own gaskets with the headers which i had to trim a bit to fit the 2v factory heads,i belive their gaskets are to suit their 3v stuff thats why they look bigger and the same with the headers,the flange looks like a D shape exhaust port like the ford 4v iron head,tomorrow i will put some more pic's of the inside of the runners but it looks quite alright,i will use this manifold with a larger hyd cam ,buy some y/t roller rockers,and will install in a few months.

I've wondered what their extractors are like, not bad for price

The bad port intake I've seen was there copy of the funnel web.

i just took some more pic's ,check this out ?

long view

[CHESTNUTXE 7,299]

some patient work will do good here,im not intening this to be a all out killer at 7000 plus,just 1500 to 5500 odd with a bigger hyd stick.

[FORD_MAN 1,026]

doesn't look too bad...

tho I'd go a edlebrock performer, will be better every where.

you will lose a chunk of torque with a single plain manifold, a specially in a low reving combo.

[CHESTNUTXE 7,299]

ive got their extractors only thing is they are thin on the tube compaird to more expensive ones.

[CHESTNUTXE 7,299]

With not much to do today i decided to pull the manifold out and port match it to the gasket,but i see a snag straight away with the intake bolts holes are slotted and not like the factory ones,so how true is the gasket going to be ? and how am i going to get it near perfect ? 

[Thom 6,650]

I wouldn't port match that intake unless your heads have already been done or you'll end up with reversion of airflow between the intake and the heads

[CHESTNUTXE 7,299]

i see yes the heads have been done before,but i didnt even think of that good one thom,so anyway i started on cleaning up the casting marks inside with 80 grit roll,and with 200 wet n dry by hand on the long end runners,no wonder these are so cheap so much crap came off just with a light clean.

[CHESTNUTXE 7,299]

The flowbench work's well,lol.

[CHESTNUTXE 7,299]

Havent done any port matching just cleaned up the casting,im glad i did this and not just bolted it on !

[ICEWOLF 53]

How did you go? End up turning out to be any good?

[CHESTNUTXE 7,299]

i sold it,and bought a different one.
