well i kno they dont make aftermarket plenums so i was just gonna port that but i dont kno what to choose for a manifold and runners theres alot of different brands out there which is the best. I want to keep the ltr tpi no superram or stealthram.

 

personally i think the arizona speed and marine runners and the tpis big mouth base are the best out of the box performers

I've been saying the AS&M large tube and Bigmouth combo for YEARS now. I know there are a few old threads out there covering this.

 

Guys, I've been researching for the right manifold runner combination same as greenbird. I'm currently used the edlebrock Vortec manifold with stock runners.

Would the ASM LTRs also be a good runner for this manifold?

Will the ASM LTR increase the plenum height?

I using a Edelbrock Tower brace and it only has about 1/2 inch clearance betweeen the brace and thottle body.

 

Any aftermarket LTR will work with any base. All follow stock height when installed.

 

i was thinking about a tpis (edelbrock) manifold with slp runners since they can be siamesed. But i dont kno if i should pick the tpis manifold or the accel superram manifold which is better?

 

SLP runners and any manifold would be my best bet. Just make sure to port the hell out of the plenum to maximize those slp runners.

 

if you have the money for it.

you would have to get their complete intake, base, throttle body, runners & plenem, but its way bigger than anything else out there as far as TPI goes.

 

anyone have any results using that system?

 

I bought the Edelbrock Hi flow runners and the Hi flow Intake. Then I bought a ported plenum off Ebay. I like it alot. Plus it looks good.

 

wow, that FIRST TPI system looks interesting... anyone hereactually have one? anyone have any flow/hp numbers?

 

The Edlebrock runners are your best bet. They have bigger diameter primaries than SLP . They can be siamesed ( ASM can't ) and ported all to heck . Out of all the runners I have to say they have the most potential. As far as bases go ... the TPIS one is a cleaned up Edlebrock unit . Accelll ...not too sure about .

 

I have the Edelbrock Hi-Flo TPI Intake Manifold Base & AS&M LTRs.

 

Damn, I wish I'd seen that First Injection stuff before I put all mine toghether....

 

Brisk, i believe someone on this site got 1 & did some minor port work on it for a NA 406 & said it pulls hard all the way to 6500 RPM. a search for FIRST inductions or FIRST intakes on the intake board may turn it up.
