Re: Dyno Test: Mod Progression
Just curious, did they say if they port matched the I/H's to the head ports?
nice numbers with out a tune or headers. JMHO

Re: Dyno Test: Mod Progression
Wow only 305. I thought mine was a little weak when it only made 320/320 stock. Most seem to make 330 or so.

Re: Dyno Test: Mod Progression
I am hoping to break 380 with Intake, Plenum and TB porting I currently have in process. Will post Dyno results when this winter's project is complete

Re: Dyno Test: Mod Progression
Do you guys have pictures to share of the ported areas? years ago I used to port match older heads , water pumps , intakes etc.. I would be interested in seeing some finish work- if possible.. For me when I get to the point of porting ,I'll send the heads to one of you Pro's on here. I won't gamble on a LT5 head..
