Trickflow has one that is similar in design to the 98 SVO and Bullitt manifolds. I don't know if it is any good, but it is another one to take a look at.

not saying the conversation hasn't been fun, or that I haven't learned a thing or 2, but this is the only reply that answered my question at all... LOL..

Anyone else know of any others? although the majority seem to be saying stick to the PI until i plan to go FI, i would still like to know what is out there. Thanks again guys for the info and help!

I couldn't tell you. My short block is .030 over, and I have a 3.75in crank. And my car doesn't make that great of power. So the changing of the cubic inch (in either dimension) doesn't give great gains.




And Injected97GT, sorry for us going off topic. lol. If you want my opinion, I say get a "your choice of intake here" and get it port matched to your heads. If you are doing it mostly for the rebiliaty factor, just get which ever one you want. There is no "magical" intake that's going to do leaps and bounds more than the others(yet). If you just want my opinion of only what I've used, the Typhoon is no better than the PI.

BBK is supposedly coming out with an SSI or DSI? manifold sometime in the near future, looks somewhat promising.

Performance wise, the plastic is a damn good manifold for our heads, even stage IIIs. This is what I am doing, larger shots can still blow aluminum manifolds, JayC has a pic floating around somewhere of an aluminum manifold blown up. If that blows up, so is your plastic, BUT the plastics are MUCH cheaper, which I will buy a spare plastic one for the case mine blows up and just replace the plastic one b/c its cheaper than buying another aluminum one.

sounds like a plan... stick to plastic 40 dolar manifolds for now, if going FI get something better flowing and port match it. makes perfect sense from what i have read so far. thanks for all the replies guys, and dont worry about going off topic. i dont give a damn, was just busting your ***** a bit [8D]

another intake choice

The .030 overbore isn't really ment to acutally increase CI (or power). You would be lucky to see a few CI with a overbore.

The reason the 4.6L doesn't benifit from strokers that much is threefold.

The first is the lack of good flowing aftermarket heads for the 2v. Without a better flowing head, the extra CI doesn't get taken full advantage of. The second is the bore/stroke ratio. The ratio is already supposedly bias on the stroke side. Increasing stroke doesn't help this area any obviously. The third is that in reality it just doesn't add that much CI. going from a 281 to a 302 is only 21 CI.. .not that great a gain.

The big bore kits are where its supposed to be at. The big bore kit not only increases the CI, it also unshrouds the valves, which helps out the weak link (head flow) in the 2v. In a big bore kit they go WAY over .030... they acutally make the cylinder walls so thin they have to sleeve the block. The sleeves are either forged or machined steel, and much stronger than cast, so they can be much thinner and still support big power levels.


I agree on the intake manifold... the gains on anything but the most wild setups are minimal with any aftermarket intake manifold on the market. Most don't make power until at least 6500+ RPM, and most loose power underneath this point (not the best idea on a 2v that doesn't make big TQ anyway).

MM&FF has done several intake tests and I have yet to be impressed by any of them. The last one they did was on a 10-12 PSI vorteched stang with aftermarket cams and all the boltons. I think they gained something like 13 WHP, and they stated this was the most gain they has seen on a car without ported heads.

I have been saying it for a long time, the stock 2v PI manifold is a good peice. People complain that its plastic, but IMO thats an advantage, as it does not heat soak. If you have a nitrous backfire, more than likely the aluminum pieces are not going to take it any better than the plastic onees, and in any case PI intakes are fairly cheap, so if it does happen its still cheaper to swap another stocker out than go with a aftermarket one (alot cheaper);

i have the trick flow manifold and its bad ***, picked close to 30 rwhp dyno prove when swapped.

Injected97GT

hmm... 30rwhp on a mod that the majority of people say is useless without FI. What other supporting mods have you done as well? Something isn't adding up here lol.


actualy nevermind, just saw you are supercharged. I plan on staying N/A and on the juice at least for this race season. I am willing to bet your power increases have a lot to do with your supercharger.

You have more power than ZW because you have more compression and can rev higher. We all know that strokers dont make more hp just a little more torque. And the reason i got the typhoon (mine is ported too) is because i had a crack in my stock manifold and wanted to upgrade so i could feel alittle better about spraying in the future
