If I do the 4.155/4.250 it equals .977 and is still considered by some to be "square" (range of .95 to 1.04) - If I could do a 4.250 bore I would. lol
I'm building another one (a 454) that's 4.185 bore and 4.125 stroke.. that's a combo I like better (bigger bore and less stroke). Now that would be and Over Square engine but it's still 1.014 and technically still "square" (but more square I guess)
BUT.. keep in mind that this block is made to go 4.250 on the stroke and due to the raised cam there's more "room". Also Wiseco is making me up a set of custom pistons. In other words we are keep all this math that makes my head hurt in mind.
Working with COMP, Lunati and Wiseco on this so I'm pretty confident it will all work out.
With the RHS block I was limited to 4.165 bore, but that's a scratch built piston unlike the 4.155. And it was either go 4.25 on the stroke or 4.125. With something this expensive I didn't think it was worth it to just end up with a 447...
I just finished a 440 (LSX iron block) build which had a perfect 4.125 bore and 4.125 stroke.. with a Fast 92 and 235 Trick Flow heads it made 660 hp and 625 lb-ft of torque. On 91 octane CA gas and 11.25:1 compression (but a big ass hyd cam)
