so i got the track heat upper and lower on the way as well as a 75 mm throttle body.

im thinking about picking up a set of twisted wedges and a tfs stage 2 cam.

will this work with a stock short block, and what RR's would i need to use?

would this be a good combo, and will it sustain 6500 rpms?

Something I saw in your original post :D

Well ... consider a thought or two about that 6500 rpm desire :)

The roller lifters we use these days are ............ HEAVY :Word:

It don't take too much to go to 6K or maybe 1 or 2 hundred more :nono:

I feel as you move beyond that ... things CAN start to go beyond the typical
street car application as the rpm's climb.

Stiffer springs, lighter vt stuff, ... etc etc etc :bang:

The commitment of money and reliability COULD cause you to to go :eek: :crazy:

Just something I thought I'd throw out there :shrug:

ah, i just went with the 6500 that the intake says.

6000-6200 would be just fine

also i do plan on gong with a 347 in the future i think as well as some boost

havent decided on blower or turbo yet but i love the idea of the boss 302 block.

the custom cam sounds like a good idea designed for a N/A combo as the car will be N/A for a long time, or at least a few years untill i beef up the rest of the car.


i do understand with the VT stuff, i just wanna get the most out of everything

I agree, everything looks swell, except for the camshaft and the valvetrain that needs to match the camshaft's needs.

A custom camshaft would be a great idea.

this is a much better plan than was your other "port my heads and get a tfs stage 1 so i can beat that camaro" plan. :cheers:

you will be much happier when you get where this one will take you

and you shouldn't have much trouble with your old friend either!

i like the stage 2 cam, and it is hard to complain about the price ...

how about injectors and maf ... those 19#ers might not be able to keep up now ... :shrug:

gurus?

well after doing alot more research i figure this would be a better route and lead to better gains, i also found a bunch of chartys graddy posted about different combos and decided to go with the twisted wedges instead.

i was under the assumtion that the cobras came with #24's for injectors?

About a limit of rpm and how the application makes a difference

We all know more serious applications usually will mean higher limits

But ... since most here are focused around a street application

We got mostly daily driver and weekend toy applications

Allow me to speak from a perspective of a Stock or OEM Stang
and
Since we got a lot of members who have NO or Little combo experience :popcorn:

Lets consider the OEM Stang experience :)

It starts to peter out W A Y before 6K :bang: :fuss:

To be a bit more specific :D

I dug up info on a couple of typical Stangs to show the starting point ;)

A stock Fox GT Stang with t5 trans reached peak tq@3200 & hp@4200

Heck Fire ... A 94 bolt on Cobra with pulleys, OR pipe, and shortys could
only muster peak tq@4000 & hp@4700

So you see :D

The power band is really narrow on an unmodified 5.0 Stang :(

This is one of those perspective kind of things :Word:

If you build a combo that will pull to mid 5K or 6K .....

You've extended the power band by a substantial amount :banana:

You really don't have to rev to the moon with a Street Car application
to make a N O T I C E A B L E improvement :nono:

Also ... if you custom tailor the band with an emphasis NOT on peak :nice:

Well ... I guess that would be another time and thread :rlaugh:

Anyway ... something to think about :)

found these at summit,

valves, 1.08/1.60
runner volume 206/96
flow cfm 305/235

intake and exhaust valves raised .5 inches over stock with a max lift of .780
and double springs


sounds pretty sweet to me and at 1140 sound like a steal for complete heads

You are not looking at the Street “Twisted Wedge” heads. They are only 170cc runners and .600" lift and they are only $1378 a PAIR. They flow 251cfm intake, 193cfm exhaust @.600" lift. The "Street heat" Trick flows flow about the same and are $1316 a PAIR. Summit sells a complete Trick Flow kit for the street that has heads,Intake,cam,rockers,bolts,gaskets,timing chain etc for about $2500.

You might be looking at the cnc tw’s or R race head or? But it is different than the street heads that will work well on your 302. Thats why it's per head not a pair.

The heads you are talking about would be way too big and not work very good on a 302 but great on a 408!

This combo should work good for your 302....in the last 5 months you have changed directions with your plans a dozen times it seems like. It would be cheaper to buy parts that will work in the future...the problem is right now...believe me I have been right where you are. I have bought parts that worked for what I had at the time,….then when I went “bigger” I sold them and bought everything again. It gets expensive buying things twice!

yea i change my mind alot, lol. part of this is because i dont wanna do it twice.

im about 90% sure im going to go with a new boss 302 block and a 347

it seems to me that the afrs or twisted wedges work perfectly here between 302 and 347

the reason for the twisted wedges is that you can get good airflow without fly cutting the pistons. but will still have room for both the 347 and forced induction

going to use either a centrifugal supercharger and a turbo setup, still not sure in that department


the 408 was part of my original plan but i dont like the idea of needing all the extra stuff to do the swap. and finding a 4 bolt 351 block seems hard.

it seems that getting a 800 hp capable short block and doing a 408 swap run about the same money (4 grand) so im going with the smaller 302 based engine so if i do end up going nuts i wont need to worry about it
