8850...sorry to hear of the dilemma with the 347, but I would not chase any ghosts just yet. I would validate the original numbers first on a good dyno with someone who knows Ford stroker motors, combos, etc. Call Steve Drier at Houston Performance...he's just about a 1/2 mile south of the intersection of Tomball freeway and Beltway 8 in NW Houston. He can schedule you some dyno time on their 248C chassis dyno and Michael or Jason do a great job getting you good numbers. Before I did anything at all, I'd confirm the numbers on a good dyno at a reputable shop. They also have a data base their of customer cars and can usually find similar dyno runs with similar mods to make comparisons. They are intimately familiar with the 347 stroker...Highly recommend them!
Also, I had done crunched some numbers a few months ago on mnay combinations using Desktop Dyno 2000 just to get some ideas on which way I was going to go, and with the stroker combos. I noticed HP increase was not huge all other variables being equal, it was the TORQUE figures that skyrocketed!! Check my signature block for all the stuff I run...now with a 347 stroker, the net numbers were as follows:
peak HP @ 5000-5500 was 410 and dropped to 393 and 360 @ 6000 and 6500 RPM respectively. With a 20% loss thru the drivetrain this gave me 328 peak HP at the wheels. For torque, it was a whopping 470 peak at 3500-4000 RPM and with 20% loss netted 376FT-LBS at the wheels. My bet is you are close to these numbers with your combo. Call Houston Performance for some dyno time and professional recommendations. Good luck...Dave in Spring, Texas
