'Pop's Engine' another 440 on the dyno.

The 440 is bolted to the dyno so I'm a little nervous and bored. The above post got me thinking about some small block flow figures. RHS LA heads 1) OOTB 1.92 intake, 2) ported 1.94 intake, 3) ported 2.05 intake and then 4) ported "J" 2.02 intake

Lift...........OOTB..............1.94...........2.05.............J 2.02

.100...........57...................77............78.................78
.200..........124.................144...........147...............139
.300..........184.................191...........203...............187
.400..........230.................234...........241...............232
.500..........255.................264...........275...............270
.600..........257.................280...........296...............292
.700..........249.................283...........306...............298

These flows were from years ago and we've learned a bunch since then. So who knows how things might change with some more work. We just haven't done much serious small block work since 2010 with the cracked RHS head (1.94 valve) on the 292ci/273, 440 HP with water roaring outta the exhaust. Welded the head up and put them on the shelf. Someday we'll pull them down and build another small block.

Okay back to the 440. I don't see why the 346 heads won't go over 300 cfm but I think it will take a bigger valve. Maybe we're all, including Cody and I, in for a big suprise as the 346 heads are the one's we've the least experience with. Yet, they are very similar to the 452's really flat port and they've gone over 300 cfm.

I think we'll be breaking in the cam in about 2 hours if all goes well. Hope none of the neighbors were big partiers last night. The exhaust exits the side of the building towards the most distant neighbors, but you never know.
