E street heads are an entry level alloy head pretty much anything should bolt up.

Got Pacemakers fitted to mine.
Don't know how they sound or perform yet as I haven't started the engine, but the fitted well.

You really just need to decide what type you want, shorties, long tube , Tri Y etc. Brands like Hedman are fine their Elite range have thick flanges, reasonable gauge pipe and are ceramic coated etc, depends on the rest of the engine spec some what, etc. Consider coated pipes though they reduce temp in the engine bay a little. Does the car have manual box some interfere with the clutch , some interfere with power steer etc

Running c4

Pretty much anything will be ok with an auto, those heads don't flow a whole lot of air, what is the rest of the engine , cam, intake carb etc considering the E-street heads I assume its a mild build?, Long tube pipes can reduce ground clearance, so if your car is low this is a consideration.

Don't know to much about engines but it's a 750 Holley and it produced 500HP on dyno.can't attach cam card as pic is too large. Let me know what you think??

500 hp with entry level e streets sounds optimistic

As Shaun asked ,need to know the rest of the engine ? Starting with what size is it for starters ? Must be a big stroker hey ? .

usajet66@gmail.com · « **Reply #9 on:** May 28, 2016, 08:30:19 pm »

How can I post dyno and cam card on this forum?

If you email me I am happy to send them through for you to have a look. Would love some honest input.

GLENN 70 · « **Reply #11 on:** May 28, 2016, 08:36:03 pm »

Don't worry about the dyno sheet . Just what size engine ,what intake and what size is the rest of the exhaust . What year mustang is this also ? . Engine specs are quite important but you don't know them so we will just have to do the best we can .

usajet66@gmail.com · « **Reply #12 on:** May 28, 2016, 08:40:13 pm »

65 mustang. Intake? 302 block stroker 347. I don't have an exhaust yet.

Running a 3000 stall and c4

usajet66@gmail.com · « **Reply #14 on:** May 28, 2016, 08:45:55 pm »

Cam intake .576. Exhaust .600

GLENN 70 · « **Reply #15 on:** May 28, 2016, 08:46:21 pm »

Ok we are getting some where now

What intake manifold ? . And now we are talking ,347 stroker and that's a big help . Don't be scared to tell us about your car because we are here to help but its very hard when we don't know what you have . Next you will be asking what size exhaust system should you run

Getting better

I would you tell you everything if I only knew. Got it built by performance unlimited in the states.I know it is risky.

GLENN 70 · « **Reply #18 on:** May 28, 2016, 08:57:06 pm »

Ok that's fine . Sounds like a big cam with that much lift for a 347 . You will need good pipes and exhaust system . What will you be doing with the car ? , a bit of drag racing ? . How low does the car sit ? Because some pipes sit a bit low .

usajet66@gmail.com · « **Reply #19 on:** May 28, 2016, 08:58:53 pm »

Casual steer driving. Not too low.
Know any good painters or car builders?

GLENN 70 · « **Reply #20 on:** May 28, 2016, 09:03:05 pm »

Sorry I don't and I'm in QLD .

usajet66@gmail.com · « **Reply #21 on:** May 28, 2016, 09:06:15 pm »

OK. Thanks. So what extractors do you recommend.

boofhead · « **Reply #22 on:** May 28, 2016, 09:52:14 pm »

Lets assume 500HP. To get that much power your going to need to peek at 7000 RPM with a shift point around 7500 RPM.
Minimum you need 1 3/4 inch long tube primaries, Approximately 30 inch pipes and 3 (if 2.5 system) to 3.5 inch (if 3 inch system) collectors about 12 inches long followed by a mandrel bent dual 2 1.5 inch system (though 3 inch would be better).

Want to come and do my exhaust. Thanks for the great advise. Can't get through to Kerry??

It wont have 500hp with E street heads unless some one has done some serious cnc port work on them they flow like 165 AFRs maybe less, E streets are 170cc in standard form Boofhead I'm pretty sure. Cam sounds like 282 XE or similar, Hasn't been stated if its a roller. If can post the brand and grind number of the cam, what the intake manifold and carb is it would help full. Boof is correct though a strong 347 if thats what it is wannt 1.75" primaries about 28-30" long. Head flow below, they are weak on the exhaust I would think they would struggle above 6000rpm

valve Lift   .100"   .200"   .300"   .400"   .500"   .600"   .700"
Intake     65     121    174   216   242   249   -
Exhaust     42     92    130   150   162   168
