What do you mean, the transmismission won't shift?

Sure, you can make over 400rwhp at 7300, but since you don't shift where peak power occurs you will need to spin it higher.

Ported TBS are shit, plain and simple and stock TBs are a restriction if they reduce power even 1rwhp. Like I saud, an aftermarket TB is beneficial once you hit 370rwhp.

The only difference maker in headers is the primary diameter, but seriously, there are no difference between all of them. Also, spending over 1k for long tubes is ridiculous.

The upper intake on the 99/01 and mach 1s does not present a constraint to making power at all, there are no mods that can be done to it that will make it more efficieint. Tell us one thing that can be done to them that will increase power. I say add a spacer and be done with it.

tremecs dont like being spun that high

stock transmissions don't like to be shifted at 7500rpm and the same goes for TKOs.

[Calogero6685]

A TKO 600 was my alternative to building my 3650, but I guess it doesn't really matter since I think I'm going to leave mine all stock. Ill probably stick with 3.55 once I get the money.

depends who's driving and what your doing when you are spinning it that high. the stock trans and tko both will shift that rpm as well, i have a couple cars doing it. more than that, then upgrades in the trans need to be done. the 3650 gets to be a challenge at 7300. a built 3650 will do 7300 fine, a redone tko will do that and more easy.

ported t/b's are good mod, plain and simple especially if an auto car. no matter what anyone says or proves, you will hold your opinion.

primary diameter and length (depending on design) are factors as well. but seriously, there is a difference. spending a grand on headers is crazy unless its needed.

you can say as you will with the upper intake, and thats your choice. i personally like to go in and do work on them while i do my lower. if i am doing it, then thats me. if you arent, then thats your choice.

you hold your opinion on how you do stuff, and i will on mine. i have done several 4v's both n/a and boosted, plenty of 2v's as well; i'm not just saying this shit just to say it.

how much hp can be gained from a ported TB, or an modded upper?

There are a lot of mods that can be done, some are even very inexpensive like a ported TB. However, those that know me are very aware that I'm all about bang for the buck and doing no mod that adds zero hp. If it takes time or money and doesn't contribute to power production it's not on my mod list.

[SWEET2KSTANG]

how much power added depends on other mods as well. porting doesnt cost me anything since i do it already. when i do customer cylinder head and lower intake porting, i will do the t/b and manifold top free since i am already there.

i am very well aware of who you are, but doesnt change my mind about how i go about modding my vehicles or my customers vehicles.

how do you advise degreeing cams?

Depends on the combo, n/a or fi, manual or automatic trans, LTs or manifolds, etc.

lol, ok I was reall specific. What I was wondering the technique. There are several differing methods out there. And also, how much advance do I need in my intake cams

Use the centerline method and for an automatic trans, heavy car like a Mark 8 set the cams at 106/114. Send me an email and I'll send you directions on how to do it. nasvt at yahoo
