Default Got the 347 Kit!!! HP estimate???

Well, I got a nice surprise on Friday. Fed Ex showed up and had 3 boxes for me that contained all of the parts to build the bottom end of my stroker. Eagle steel crank, forged rods, forged pistons with floating pins, bearings and rings, Balancer and flexplate. The kit is already balanced so it is ready to install. The reason I was surprised to see it was because the pistons were supposedly on backorder because they are .060 over (so its actually 352 CID) instead of the normal .030 or .040. over. Anyway its here now and Im going to pick up the block on Monday morning and start assembling the motor. I absolutely cant wait to get this thing running! With the Edelbrock Performer RPM heads, and a 284H comp cam (284/296 deg. dur. & .541/.544 lift), and Edlebrock air gap intake and a 650 Demon carb, and of course long tube headers, and complete MSD ignition, how much HP would you all expect to see out of this beast???

I concur,,, about 400 or a little + (425?) at the crank...

It will be a strong runner... it should be a blast to drive!!

Thanks guys! I went with the Edelbrock heads b/c I initially bought the total power package from them, but their cam was a piece of crap- long story, and it rounded off and ruined my whole engine, so now its getting stroked. If I had it to do over I would go with some Trick Flow twisted wedge heads; they are cheaper and are supposed to be a little better. But the Edelbrock RPMs are god heads too from what I hear. A neighbor of mine has a set on his 351, and it is absolutely bad ***!

I would say 400 with the proper tune on it. You know that the cylinders have to be notched to clear the rod bolts right? I just want to be sure you don't put it together without doing that first.

the trickflows ported are nice *** heads no doubt. your current heads will hold back the stroker some
