So I have a 347 windsor had It on the dyno it made 303.6 rwhp and just over 1250 lb tractive effort just wondering is this good bad or other will list parts to see if this sounds right to anybody.
Note some parts are procomp and holding strong.

Here goes:
5.0l roller block stroked to 347 (procomp)
190cc alloy heads 2.02in 1.6ex (procomp) all hardware (compcams)
Xfi248hr-14 camshaft (compcams)
Parker funnel web intake
850cfm demon carb
1-3/4 4-1 extractors
Running 42deg total advance
4.11 diff gears
5spd manual.

Issues found at time of dyno:
Too much total timing
Spark plugs too short need .750 reach
Heads stopped flowing at aprox 6500 rpm

Currently fixing issues then will take back to dyno. Again just wondering if these figures seem about right. As car breaks traction accelerating in 4th at 4000rpm

Sounds about right. Best I've heard is 250ish rwkw

Procomp heads are junk and don't flow anywhere near what a good set of AFR's or Trickflows would, so seems about right.

Thanks for the replies. Fixing issues now then putting it back on a dyno in ballarat maybe it was done out daylesford first time (did great job out there and very helpful with questions) he said his dyno is mean and other dynos probably give readings on the happier side but if I fix my issues could net 40-50 hp.
He also said heads in the 215-225 range would wake my combo up so
Question; do I put more money in the heads I have now or buy bare heads and start again?

wait till the dollar go's back up and look on jegs or summit ,places in the usa and get a great set up just type in sbf,i have a set of 185 outlaws on my 302,you could go a good set of 225 will really make a difference or chb heads also use good rockers that are fully adjustable so you dont need to shim

Ok thanks will keep an eye out. Also I need to get a 9 inch made any sugestions on a good place in Victoria as I have gone through 3 borgwarners, smashed LSD centres on all 3 and 2 twisted axles. Thanks again for all help.

just get a 31 spline conversion,or you could get a 9 in 31 spline made to fit your car its gonna cost about 2- 3 g ,their is lots of places on ebay they have a contact info for their shop most of the time that would be a good place to start its just time and research to find what you need for your setup ,both can be done at a good diff shop

Mate, to be honest I would have thought with that intake and carby it should be making a crap load more so those heads are definately holding it back so work towards replacing them.

Even with also turning a 4wd transfer and 32" tyres etc my efi 347 4Runner makes 364rwhp and 510rwnm and without the airbox lid (a restriction) 375rwhp yet it only has a custom mpg cam and idles like a stocker. So in a normal Falcon it would be over 400 no problems.

The engine internals are all good gear with AFR 185's and a TFS Box R manifold, 90mm TB and 90mm Maf.

The 347 needs to be able to breath :D

First things first, s**t parts will make a s**t motor. There is absolutely NO need for a 9" the LSD issues are because the Borg Warner LSD is s**t. TrueTrac and 28 spline axles will more than cope.
