Got my hands on some TF 240's with flowbench results

Found it so I dropped it here -


"I don't know where the customer acquired them but I was shipped a pair of TF 270's for the upcoming Twin Trq-Storm SC 452 build. I disassembled them as a spring change is in order amongst checking the guides and seat work. Pulled up Trickflow's advertised flow numbers and put one on the SF-1020. I have a doweled plate that mounts the head perfectly as it would be on the block and the bore insert I used was exactly what TF states = 4.350".

Very impressed the flow numbers are pretty much bang on.

.100" 71.7
.200" 154.9
.300" 228
.400" 285 <<<This is a stellar flow rate for a conventional BBM
.500" 319
.600" 339
.700" 351

Well done I'd say. Now I'd like to see the small block TF's--At this point I'd trust the TF claims. J.Rob"
