@gunforme I have never dynode my mustang, but the guy I go to no's what he's doing! I have a video on my page of his 10sec 347 N/A! I have unported cobra upper and lower manifold. gt40p heads unported, hardened push rods. dss 331 stroker, forged pistons, rods etc. 30# injectors 10;1 compresson ratio. Comp cam. 190lp fuel pump, bbk shortie headers, bbk pro-chamber x-pipe no cats, flowmaster 40's. 70 mm throttle body, 75 mm mass hair . cold air! Soon gears and posi!
DId you have a fuel issue? Numbers are low. I know some might think it is the procomp heads since they don't flow as well as TFS, AFR, etc. but procomps are capable of more than what your getting so something else must have been wrong.
my 347 had a tfs stage 2 cam procomp 175cc heads edlebrock rpm2 intake, 30lb injectors, longtubes 75mm t bodie and made 338rwhp 391rwtq. check out mine!!
Is it an auto or standard?? Second either way those 190cc Procomp suck.. You atleat need the 210cc procomps and still have them ported.. then you would probably gain 50 to 60 hp. I bet gt40P heads would even produce more power..
The heads are holding you back man, Pro Comp sucks, I have machined at least 20 sets and they are truly s***t castings, drop the Pro comps and that engine will grow to be a beast.

@Di4bl0Azul326 I'd like to see a dyno sheet on that one. It might be possible, but not without some work. You got a video up showing the dyno sheet?

Why numbers so low. Doesn't add up? I have a 331 stroker with gt40 iron heads that make 350 hp

howd the heads look new? did you have any porting done, milled, etc.? How much did the porting/cleaning up cost?

Those are LOW numbers. I had a stock 302HO short block TFS1 cam. Pro Comp heads and a edelbrock rpm air gap and pulled 399hp and 368lbft.
