Estimate my 347's HP

[thekid760]

I also posted this in the 5.0 tech section.

My engine setup:
347 kit w/ 5.4 rods, cast steel crank, and Speed Pro hyperutectic pistons.
1978 302 non roller block bored .030 over and clearanced for crank
Stock 78 heads rebuild, and mildly ported by me
1.6 roller rockers
RPM air gap intake
Holly 650 DP carb with mechanical secondaries
Isky solid mech cam Part#: 381358 278 adv duration 244 @.050 .512 lift 108 degree centerline
Hi volume oil pump
stock pan
1 5/8 long tube ceramic coated headers
MSD pro billet distributor
6al ignition box


What would you estimate my setup would make?
This will eventually be paired to an AOD w/ 3000rpm stall and 3.73 rear gears.

Any comments or suggestions?

might get 320-330 hp from it IMO, all that duration is gonna move the powerband into the upper end of the rpm range where the heads will really be hurting you. I dunno.....seems an odd combination of heads and cam, especially on a stroker.

http://airflowresearch.com/articles/ultimate/Group3/Part6/A-P5.htm You did not list CR? I think it should make 350 hp at least. Towards the bottom of the page is proof that stock iron heads are capable of decent power.
