finally decided

[autumn_again]

okay, so me and my dad are talking, and we are going to build up a mild n/a motor for my mustang.

302 block, maybe bored to 306.
aluminum heads,
roller rockers
mild cam.
bigger fuel pump
bigger injectors
new maf
long tube headers
offroad x pipe
custom fabbed side exit pipes with spintech pro street mufflers.
msd 6al
smog pump deleted.


i'm trying to make a list of stuff i'm going to need, we're rebuilding the bottom end.

i'm looking at AFR 185s or Trickflow track heat heads.
rockers not sure what ratio size
cam, i'm kinda clueless on.
what size fuel pump am i going to need?
what size injectors?


anything major i'm missing?

ill be running a set of the track heat heads, a 1.6 comp cam steel RR, a 255lph fuel pump, 30 lb injectors, 80mm PMAS MAF, 75mm tb, etc etc...

Are you on a budget? I notice you have a T-trim and cobra manifold waiting to go on. If you are, you might as well just do a budget bottom end rebuild or even pick up a used motor from a junkyard/classifieds. Use your stock heads/cam and upgrade to a 255gph fuel pump, 42lb injectors, and a good tune.

oops my mistake, i didnt even see that he had a t trim for install...

i think i'm going to sell the t trim.

either that, or the drag car we're building we'll throw it on.

i only have the actual charger, and 2 brackets and the power pipe for a foxbody, so all the other stuff i still need.


budget, not really, because i want to do the motor right, i am just going to save up and build. i don't want to have a set plan for the motor, and then decide when it comes time, well i guess this would be good enough.

Save your money on the Might Suddenly Die aftermarket ignition

If in good working order ..........
The OEM ignition is perfectly capable :Word:
of sparking a very powerful NA combo

Sounds like a nice project you and dad are going to do

I'd go with 1.6 rockers and I prefer stud to ped mount

I'm a firm believer in the custom approach when talking cams
You get to be specific with your goals for the power band
You get the benefit of cam guru's knowledge
and more

Of course ... Tried and true ots bump sticks are available
such as TFS1 and the like

I'd do a 255lph pump and 30# inj's

Do it all up with a nice sharp tune to obtain maximum power and drivability

You are going to make substantially more power
therefore
You most likely are gona have to step it up with your cooling system

I run a Stewart High Volume pump and Fluidyne radiator to
keep things cool ... even in hot Texas summers

Just a few thoughts that came to mind ... so far

hm. i got the MSD real cheap, never used, import guy thought it would work on his car, too late to return it, he sold it to me for like 120, think i should still install? or sell?

1.6 rockers, are there any benifit to them over 1.7? i'm only asking because incase i see a set for sale for the cheap, but they are 1.7s, i would wanna know before i jump on them and be dissapointed.

theres a couple big 5.0 guys in the neighborhood, so i never know what i'll see on craigslist.


the main concern i had was the injectors, i was going to go with 24 lb, i wasnt sure if 30's were too big for N/A.


i was thinking of ordering some parts soon, to start getting stuff together for the build.

i was going to go with rockers, fuel pump, injectors, new maf, the throttle body elbow i need to run the intake, and the full exhaust. save up for the heads, and custom cam, and then after that start saving for the bottom end rebuild so this way i'll have time to think it out thoroughly. just got a $1.50
raise today, and more hours, so i should be rolling in cash. :SNSign:

 

[BlownFiveLiter]

Install the MSD if you're installing the T-trim, otherwise, I'd sell it for a quick buck. Going with 30's wouldn't hurt, if you're going HCI. It never hurts to have some room to grow. I have a V2 SQ that I'm gathering a few more parts to install and I'm going 60lb injectors with that! Of course, the Mustang isn't my DD, so when I kill the stock block, I'll start saving for a Dart, or if I can find one, a used A4 or R302 block. I'd find a decent cam and see what rockers it's spec'ed for. Typically, it's for a 1.6 rocker. If using them with stock heads, save your cash and wait until you have heads before buying some rockers. No sense in spending $200+ on some pedestal mount rockers, only to have to buy stud mount when you get some heads. I think Grady has you pretty well covered on just about everything else!

 

[autumn_again]

nah i was going to buy parts and just collect them till i had all the things for the install. i would probably install the exhaust, then the rest just have in a box in my room till i had everything i needed for the new motor. this way its like a whole new beast to me, not just little things at a time, and just get used to it right away.

alright, so i'll hold off on the rockers until i have a cam picked out. maybe i'll buy rockers, heads and a cam at the same time. went into work today and got new hours, so i'm going to be working about 20 more hours a paycheck, with $1.50 more each hour. so within like 2 months i'll be able to get a set of heads and cam and rockers after getting all the other parts.


edit. how is the stock distributor for when i'm making more power?

i just threw a new one on probably 3 months ago, because i desperately needed one, found an oil leak puddled near where the dizzy bolts down, took the cap off, full of oil. so i threw a new dizzy, cap and rotor on. it didn't cost me much because i gave them my old one for a core replacement.

 

[final5-0]

Yes ... Like Matt said

Why buy rr's twice when you can easily plan ahead

Of course ... if talking TFS heads your only choice is studs
but
Some of the other head choices offer peds but I REALLY don't like peds

I focused on the 1.6 ratio simply cause you got more options with em as far
as cam capability as opposed to the 1.7's

About inj size and NA combos

For some reason
A good bit of the time, peeps are reluctant to go bigger on size unless
they see some hard data showing how stressed they are working with
the info usually being supplied to them by a tech while their Stang is on
the dyno.

Couple things to keep in mind here

You can see very mild (OEM h/c/i) NA combos pushing 24's to the limit all
the time if you hang on some of the tuner sites ... AND ... I might add that
is with the owner running elevated fuel pressures

A lot of the time ... when you custom tune ..............

You DO NOT run elevated fuel pressure
so
No matter the size of inj ... its not gonna act bigger at OEM pressure

Honestly ... a lot of this kind of thinking is probably a throw back to the
old Fox days when not much tuning was being done other than twisting
the dizzy and upping the fuel pressure.

These days you have access to the pcm so it is cake to dial back the fuel
a bit at low pulse width conditions with 30's or larger sized inj's

If you go with the SN tb setup

I'd NOT go with the Edelbrock elbow for two reasons
1) It does not present as smooth of a path for airflow as others
2) It is smaller than others

I'd go with the TFS elbow

Finally ... Ignition

Again ... Like Matt said

Forced Induction needs more juice to keep high rpm spark blow out at bay
but
For NA ... The stocker is more than fine for whatever you want to do

For NA ... an aftermarket ignition won't hurt anything
but
Its one of those mods that drains the ole wallet for very little hp gain

[autumn_again]

i was thinking of going with the professional products one, but i dont want to go cheap on something when i may feel i wish i went better originally and buy twice.

so MSD i'll save for another time.

alright. i think i'm going to place an order for subframe connectors, and do the exhaust. then after that probably fuel pump and injectors.


is the stock distributor fine for naturally aspirated combinations?

Yes

The OEM dizzy , coil, and everything else that is part of the OEM ignition

Just as long as it is in good working order ... that is

[autumn_again]

alright cool. that makes me feel better then.

i cant wait to start ripping into the car, making it a beast. hahah.
