Of course you can get 520 HP but not with the specification of parts that made 447 with the 327.vortecpro wrote: ↑Sun Mar 20, 2022 9:47 pmThink I can get 520 HP? I know I can get 465 TQ, my 327 had 400 TQ for a 100 RPM spread, and 390s for a wide range, should help the launch.skinny z wrote: ↑Sun Mar 20, 2022 9:21 pm My Moroso slide rule says you'll gain about 3/10ths, all else being equal.
That is to say, 1.37 HP/CID.
Always liked your builds, posts and results. Nice to see you and your son getting on with it.
Do you have a thread documenting the 327?
As for advice on how to build the 355, I've got nothing to offer that you don't already know. If heat is an issue, maybe a Air Gap style intake but that's about it.
I'm staying tuned for your next move.
400 TQ from 2000 to 5500 is my guess for the 355. At least that's what my aftermarket Vortecs and small hydraulic roller 357 is predicted to dyno.
So the question is, what will be the next spec? I suspect not out of the box Vortecs.
