Please point me in the direction to where you buy your parts. Those prices are no where near practical. Unless your buying something that needs completely rebuilt, even then, good luck.

I see where 5spd GT is coming from. The kit may cost more and not net you a big gain over the stock GT40 stuff but you are buying piece of mind too. It is a complete brand new top end for your engine. Not to mention better quality.

FivePointOhh

im with adder on this one. better quality? quality is only as good as it performs. GT40 for only an avg. of 10-20hp less than the very expensive trickslow kit...id save my money and go gt40. trickslowyour thinking ooooh its brand new and shiney aluminum heads and all new parts. GT40 set up is cheap and it works. i called junk yards, they didnt have em in but they told me they sell theirs for 75 per head and intake for 90. it avergaes out almost the same. depends where live iguess. ask anyone on this forum what they make with that trickflow kit its not over 300 thats for sure.....id shyte if i seen a dyno paper than says over 300hp to the wheels on just the top end kit for trick flow

and if you've seen several mustang make over 300 to the wheels what was their power adder because thats the only way they're getting there.

Yeah the trick flow kit is tested on a fresh 306ci engine with 10:1 CR, Big TB and MAF, etc...

It's not going to put down the same numbers on the avg. joe's 100k mile factory 302.

5spd GT

You are buying used parts. You could buy much of the Trickflow stuff used, and you could get that cam for that price NEW.

I got ARP head bolts for $40. You were getting ripped!

The trickflow comes with WHAT YOU NEED. You get a timing chain, new hardened pushrods, new roller rockers, head/intake and all the other misc. gaskets. New valvetrain.

Here is everything you get:

Trickflow H/C/I Combinations:

Street Heat Kits for $2,450:

TFS-K514-350-370 - Street Heat Intake/Street Heat Heads (smog provisions).

TFS-21406700 - Pushrod Set of 16 -6.700�
TFS-51400904 - Head Gasket Set
TFS-51400801 - Cast Valve Covers or TFS-51411801 for Black.
TFS-51400004 - Twisted Wedge/Street Heads, ask for track heat head upgrade confirmation.
TFS-51500001 - 5.0L Track Heat EFI Intake Manifold
ARP-154-3601 - ARP Head Bolt Kit
TFS-51400800 - Oil Fill Kit
TFS-51478520 - Billet Timing Chain Set
FEL-TCS45449 - Fel-Pro Timing Cover Gasket Kit

Extra Notes:
The street heat intake has 15 inch runners and the track heat intake has 12 inch runners.

The street heat heads come with smog provisions and the track heat does not. The track heat heads can be ported a bit more because of this.

Both the street heat and track heat heads come with 3/8� rocker studs and the track heat heads can be upgraded to thicker 7/16� rocker studs. Just call your sales representative to get the upgrade.

Both street heat and track heat versions have the option to come with dual valve springs and 10* locks.

Twisted Wedge and Street Heat Heads are the same, not to be confused with Track Heat.

The trickflow h/c/i packages are more designed for the fox-body cars do to valve cover tallness and throttle body adapter plate not being included.

You are not comparing apples to apples. If you are going to compare, atleast stay in the produce aisle

You have not proven anything, except that you can get heavy iron heads at a junk yard.

If any is refuting the fact that 300rwhp cannot be made with a trickflow h/c/i kit, with supporting bolt-ons, they need to get out of the game

Just google it, and see all the 300rwhp combos out there.

Matter of fact, this should help you.

I would go Holley over T.F

Mustangkiler

Last time i checked out that holley kit it came with a flat tappet cam, although info on summit has been wrong before.

jhall01

If i was gonna buy either one i would go with Holley just because i trust the Holley name more than i do TF. I dont feel like im alone on that one either. Im with Adder too why spend that much more money on something that only gives u a few more HP. Unless u just happened to have that much extra money laying around. I know i dont.

5spd GT

The old holley set had some valvetrain issues if I recall. I believe there are 3 configurations of heads possible from Holley, some coming with a 1.9 or 2.02" head. The valve angle of 17* allows the use with stock pistons.

However, the Trickflow heads are much the same, in valve angle and portability. They are not as 'old school'.

The Holley Systemax is a GREAT intake, but the kit with it's camshaft (hydraulic roller for EFI kit), leavessome to be desired. The Trickflow has a slight edge in cam design for that kit, and the overall packages matches better.
