I recently bough a SS Hatch, it runs a 308, 3500rpm stall converter and Trimatic. I can't tell you much about the engine's spec's, I believe that it is running ported HQ style heads, an after market hydraulic cam (fairly lumpy) and factory manifold and Quady. the other week I took it down to Eric at Goodguys Performance Centre for a tune and by the end of the session it was putting out 173rwkw @ 6000rpm according to the dyno. Eric said he believes an after market performance manifold would really wake up the 308 and recommended the Torque Power single plane manifold, as I have a 3500 stally the lose of the low down torque wouldn't be much of an issue.
What do you guys think? What manifold would suit?
How would an Edelbrock Torker go on my combo do you think?
Suggestions for manifold to suit my 308

Thanks for your reply
Who makes Stripmaster, what RPM range do they work in and who stock them?

A Torker should liven it up a bit, But a Performer may do a better job. The Torkers are single plain and i think you need a fair bit or power to make them work to their optimum. Or if you want to go Straight Gas the Torker would be perfect! haha I got a Torker on My motor at the moment, and i think my car would go better with a Performer...

I'd be using the Performer.
FWIW the car that is in your avatar that used your ID for number plates used a Performer to run low 11's years ago.

Run a Performer, maybe add a 1" open phenolic spacer if you want to improve the top end HP.
The Torque Power is an excellent piece, but its more suited to a 355 than a 308.

That is true, be it an extensively modified performer.I'd be using the Performer.

Thanks for the input guys, I think I will give the performer a go and see what kind of a difference it makes.
P.S. Struggler, My SS is the one in the same, with a different engine.

Hey 1BADSS, my turn to welcome you to my digs, this is the spot for Torrie info.
From all the things I've read, the Performer seems to be the best manifold suited to the type of combination your talking about, and most of those seemed to use a spacer as well. Struggler and Bottledup are two of the best blokes to listen to around here when it comes to engine stuff. Worth a try i reckon.
Cheers,

As I said I will look into the Performer but why not a Torker? At the moment it is making 173rwkw @ 6000rpm, wouldn't the Torker suit the higher rpm range?

On an engine dyno the torker was worth identical HP and heaps less torque everywhere compared to an off the shelf Performer on my 308/326 stroker that had a bigger cam and more comp than your combo. The Torker never beat the Performer, anywhere. Closest was within 0.5 HP at 6100 rpm. This was the Torker's peak. Performer with 2" spacer didn't peak until 6300. The torker was tested with a 2" open spacer, without it it was worthless.
Just my experience.

i agree with struggler, the torquer will only show improvement over 6500rpm so you will need a pretty big cam and very good heads to use it. it really comes into its own around 7000rpm+. i remember seeing a combo in a blue lj in a mag years ago owned by a fella named sherif tawaf. it ran a std stroke 308, 288 cam, 750 vac, performer manifold, 2 in open spacer, 1 7/8 pipes. 3500 stall, 3.9 gears it ran constant 11.60s @ 118mph, no nos. also seen a hatch with a performer, std stroke run 11.40s. dont under rate the performer they are a freak on 308s. ive seen it for years and it still amazes me how much power they can make.

Cool. You mentioned a 2" open spacer, does this create any air flow issues with the Performer as it is a duel plain manifold?

The 2" spacer I used on the Performer had a divider running the full height of the spacer, this produced better HP and a truck load of torque more than the same spacer without the divider.

I`d just like to add my performer was junk on my combo and wouldnt rev past 5500. The change to a stripmaster picked up 21rwhp and no noticeable loss down low.
However my stripmaster is now gone and replaced by the torque power hehe

To fly, what engine spec's do you have? how is the Torquepower over the Stripmaster, much of an improvement?
I under stand that you guys have experienced good things from the Performer but could you please explain to me if my V8 is making power up to 6200+rpm with a factory manifold, how the Performer that spec to only deliver power to 5500rpm will suit my combo better than a single plane that will deliver power to the range that my combo is already making power.

Thats where I think the the spacer comes in it, lifts the power range. Better wait for someone with personal experience to confirm that tho...
Edit: Don't know if you've been following the thread on aussiev8 but the new TorquePower hi-rise dual plane might be something that will work for you. I havn't heard enough hard facts to sway me either way yet, but might be something to look into.

Ian Tate has just built me a lovely engine to go racing with.
Dyno sheets show 435 Hp @ 6100 rpm
Manifold ?
Performer.

Im running a redline torker and im pretty happy with that , also running a 1 inch spacer . I used to have a performer manifold on it but when upgrading heads and cam i was advised to change to single. Either way i dont see much down low loss especially now with my 3500 stall. I think you may end up hearing alot of different views Grant but what are you to do, it would be nice to borrow 2 different manifolds and see which seems better and then test them on a dyno. What are your plans for the future?? Bigger heads ? Vn style ? Might be an idea to wait and find out what direction your heading before spending the money on a manifold. I have heard the strip master is a real good manifold but i suppose your engine has to need it before it performs. I hate these decisions , good luck .
PS i still think our hatches should spend the night together hope get some nice offspring.

mate i would not go passed a performer these are some cars i know with them
my lc std stroke 308 / 286 6500rpm 12.1 @112
mates lh std stroke 308 /288 7500+ 11.8@112
mates vk std stroke 308 / 288 7500+11.2 @118ish
so they work on 308s
and 1 quick lj sherry is a mate of mine and that blue lj runs mid 10s these days
