Default To port or not port?

I just finished my 347 a few months ago and have since put about 150 miles on my setup. I was shooting for around 400 rwhp but came up short like I kinda expected. I considered putting a blower back on but really dont want to deal with it and would rather keep it all motor. My current setup is 347 Eagle kit, trick flow street heads, edelbrock victor jr intake, ford motorsport roller rockers, custom hardend push rods,Trick flow camshaft, 42lb injectors, 75mm throttle body,80mm mass air meter, aeromotive fuel rails, 255lph fuel pump,bbk cold air intake. So I'm thinking porting could help me get closer to my goal if not there (which I doubt). I want it to be streetable since thats mainly where its used. Any suggestions on who to use? I'm considering fox lake.

Thanks,
Steve

whats your compression, what TFS cam are you running and you need a 75mm TB and 76mm+ MAF.

you also need 1.75" into 2.5" longtubes, and corresponding mid pipe and cat back.

you'll get there, dont worry.

The compression I honestly dont know, havent checked it. Actually I just checked the car its a 75mm throttle body, thought I had a 70 for some reason. I have a 80mm pro-m mass air meter. The exhaust is 1.75 primarys to a 3" dump system. The camshaft is TFS-51402001 Duration 292/290,Lift .542/.563

Seems low. Did you do any port/gasket matching when you did the assembly?

that's what mine put out with a ****ty tune. I was going to go to lidio as well but there's a few local mustang i know that went there and made **** for power. his tunes are WAY too conservative, i'd suggest getting someone else to mess with it. I know you want it to be safe but there's a safe tune and there's a stupid safe tune which is what i hear lidio does.
one of those local guys went to a guy in mt pleasant, mi(not sure where in michigan you're from) and got another 28hp and 32 ftlbs out of just a tune and it's still very safe.

I would agree with what has been said.

Some trick flow fast as cast heads, and custom cam, then tune would wake it up.

Finally someone else that got the trickflow stage 2 cam haha
