Porting 4.6 PI Heads
 

Anybody have this done? Results? Thank you.

I'm considering having this done as well. Very interested if someone has results :)

Who is going to do the porting ?

there is only one shop to goto, Rolling Thunderz. Flowbench, cnc and all the goodies. everyone else is a hack and or ships the heads out to RT and bills you more.

:tup

Any idea on the gains?

Best to call them as they do all the calculations for ya.
You will need a nice combo like MTO. He has dealt with them before...

I believe mto had 100 RWHP gains.. but best to talk to him Jack

Actually I gained more Rick. Remember what it dyno'd stock ? :rolleyes:

It was more like 133 rwhp SAE numbers on the dyno but that was including aftermarket exhaust, intake etc etc and all the other supporting parts.

I'm not all that familiar with modulars though. Paul, you do realize of course that you'd be falling under the old retuning issues after having them ported right?
What, you're not happy with all those ponies you have now !?!?

I was hoping I might gain 50-60 RWHP with cams, porting and tuning. Add a few more suspension upgrades and I'm done. Keep the car for 20 years and it will average out to 5g's a year. :bang


BTW Road Narc...where's my Mosport DVD!

Still in the Stang, stored for the winter :)

I would think you'd be able to gain at least those numbers, but at quite a cost !

hey 2tone
 

You sould like Mel 2 years ago.Didn't he take a set of heads to RT and the car was a stone.Those clowns shouldn't be touch cylinder heads.
I can name you 10 people who they screw,that I know of.
They also like to play games with there flow bench

RT engines------------If it doesn't have NOS its a stone

If you want the true flow numbers then flow it on a superflow 1020
There's only 2 in ontario,and there not at BLUNDERZ
