Endurance Short Stroke BBC
Beginning to plan out my next engine build for the ol' Formula. Currently have 454's with 500efi cams. Wanting to build a 500+ cubic inch short block to use with my current 310 Merlin aluminum heads. 600hp goal with longevity and reliability in mind. SRP has a piston for 4.560" bore that I could use with new blocks and a 6.385" rod. That makes a 523cid. Does anyone have anything similar with a 310cc cylinder head? Toying around with the idea of a Solid roller cam as well.

That would be a nice combo imo. Solid roller not really needed, being that you mentioned "longevity". That combo, a decent cam, should do 600hp without breaking a sweat using a hydraulic.
That being said, a 523ci, 10:1 solid roller 6500rpm setup, has a nice ring to it.
Vintage chromoly built a 516ci if i recall, made some good power.

Just a good crisp sound. I have the Imco powerflow manifolds and long tailpipes for the TRS.

You can't do that with a HR ? Oh, is your exhaust dry ?

Exhaust is wet but does dump pretty far back in the pipe. I know a Hydraulic Roller would do it. Wondering what effects taking weight off of the valvetrain would be with a solid lifter setup. They will probably end up with 741's or something similar but it doesn't hurt to experiment with the idea of a solid roller.
