Would like some constructive criticism on my 302 build.
Well II fans I've come down to a few different choices on my 302 build. I'm going mainly for a Mild Street/Strip Build, not looking to build a monster but still want to pull decent 1/4 miles(13's). This is what I have so far.
GT40 or GT40(P) Heads
Edelbrock Intake Manifold(RPM) (1500-6500)
Edelbrock Carburator in 600 or 650 CFM not sure
A Cam that would work alongside my other options. Open to suggestions would like some lope.
Headers(Suggestions?)
Full exhaust with either SLP/Bassani/Mac Mufflers
3.55/3.80/4.11 rear end gears looking for a decent top speed. 100+
Sparkplugs?
Coil?
Wires?
I've heard a lot about the Duraspark in my 76 and how good of an ignition system it is. Is this true?

would you want to stroke the block and add a bit higher compression to that list?...seems like what you have is all NA Power mods...and that would complement the rest of your components quite nicely. as far as ignition look at MSD.
would you like a list of stoker components? Or fabricators that will do that in your area?

This has been covered many, many times in the 5.0 talk about what 302 combinations would be best.
Need more info like:
still going to be a 302? or bored? or stroked?
decide which heads you want
nice intake choice, keep that one
what compression ratio?
what's the budget for the build?
is smog a concern?

Staying 302 may go S/C some time in future may not.
Going with GT40 or GT40P heads what ever I can find easiest at junkyard.
Stock Comp ratio is 9.5:1 heads would likely make it 9:1
Budget is as cheap as I can have it what I have listed is about what I can afford ATM.
Smog is of no concern.

I was thinking of putting "AFR CNC Alum. Head for 302/351 - 165cc", but for $1,500, I don't know. But besides that I too am looking for help on a Mustang II 302 buildup, but that will be a while.

Heads good Intake good Carb is ok if you know nothing about how to tune carbs, if you do know then a Holley 650 DP or a 750 vac sec. As for a cam, what you have to keep in mind is it a street car, and toque rules the streets not Horsepower, so keep the dur. Around 230@050 and the lift as high as your budget will allow. Headers- Hookers & flowmasters Put as much gear as you can live with and still drive on the freeway Mine runs c4 auto 3000 stall, 3.55 with a 26" tall tire and spins at 3000 rpm @ 60mph Sparkplugs-autolite Wires-MSD Duraspark DIST. W/MSD 6 BOX

I had the same dilemma. I pulled the old block and went with an '87 302 roller block. I also wanted to stay in the 2500 to 6500 rpm range, so I went with Ford's X303 cam, Victor Jr. intake (RPM intake is a good one also) with a 600 cfm carb.(vacuum secondary is better for street use), and a 4000 stall torque in a C4 Trans. with a B&M shift Kit. The car pulls really hard and stays up in the high rpm range. I also went with all MSD ignition, and Hedman hedders, Flowmaster mufflers and all 3" exhaust.

just wondering what your thoughts are, on why a vacume secondary carb is better for the street.

A vacuum secondary would be better for street due to the fact that you are not always going wide open throttle on the street. With only two barrels open, you are using less fuel, and when you go to wide open throttle, all four barrels are open for that increased demand of fuel and air. A double pumper (mechanical secondary) is better suited for drag racing.
A quote from Holley Tech :
"For street cars the vacuum secondary carburetor works best on midweight or heavyweight cars with an automatic transmission. They are more forgiving than a Double Pumper is because they work by sensing engine load. The mechanical secondary carburetor is best on a lighter car with radical camshaft and a lower gear and manual transmission or on a car that is going to be used for racing purposes."
This is a good topic for debate and has been for years. I just found that the vacuum secondary works best for me (more street then strip).

im attempting the same outcome with my build. so far i have a 60's 302 not sure what exactly until i check the numbers on the block, torker intake, e7 heads, holley 750 dp. Originaly came w a holley 600 which was choking the hell outta it, when i put the 750 on it livened it up 100%, just not sure what cam i want, i know i want a pretty good agressive sounding lope. how much better are gt40-gt40p heads, and what r the differences between them. lookin to basically have a great sounding eng and performance as well. doesnt everbody lol

I build mine mainly for the strip but it's fun to drive on the street too. I use a Victor Jr single plane intake as well and love it. I use either a 700 or 750 mechanical on top. Lots of instant punch with mechanical carbs. It works surprising well on the street but you have to have good flowing heads and exhaust. I use old 289 hypo small chamber heads, ported and polished, and machined for larger Chevy (gulp) valves. Good springs and Harland Sharp valvetrain with a 292 Comp Cams shaft. Nice and lumpy. 9.5:1 forged pistons, but compression may be higher with the heads. A 3500 stall lets it idle in drive with a C4 trans. Believe it or not, I built the engine following a basic "recipe" from Jack Roush in an old Hot Rod magazine. Your parts have to work well together. Still use the stock Duraspark with lots of static advance, but the vacuum unhooked to avoid detonation on the street.
The car has 4:30 gears in the 9" so freeway is out of the question, but it worked well when it had a 3:55 rear.
Would like some constructive criticism on my 302 build. 
IT'S ALIVE !!
