Steve, I think it would be a monster in a 427 with Trick Flow heads and a steep gear. Assuming a good ring set and bore, proper build, my estimate would be around 560 HP and 550 TQ, likely peaking at 6000 for a 6300 RPM shift point. The narrow LSA gives 78 degrees of overlap which should work really well on a short stroke FE with a fast port like the TFS
In fact, if it didn't sell, I was going to play with it in a stock stroke C1 iron head 428 I am building to experiment and likely sell, but it will work much better with the TFS heads and a 427
This is a decent lobe design, Crower is nothing to sneeze at, a custom flat tappet may gain in some areas, cost in others, but this is a pretty good match for your combo. If I was going custom and staying flat tappet, I might sneak a little more lift out of a lobe, but then you are likely going to have to swap springs.
The 1.46 OD Ttick Flow heads will have s decent spring, I'd likely make sure they are no looser than 1.875 for 120 closed, 340 open. It'll be a long way from bind, but it's a good spring, could think about going with .050 keepers for break in and end up at 1.850 as well for a little more pressure
Let me know, unless someone is in the background ready to pounce
the only place it may go is my 428 and I have a few engines to deliver first
