Theres a 5.7 345cu base vvt motor that is at 427cu. (not 426)
I asked the same thing about how the builder got to those cu and if there was over heating issues, or was it an oil burner. Answer, NO None. ?

Unless I'm mistaken, isn't this similar to the motor that Stack Performance is running in Sam Hubinette's Challenger?

Bringing back an old post. But i didnt read anything about the piston size being different... not just a simple stroker kit. I know the size difference is great but im just curious

Since the 6.4 is a bored and stroked 5.7, is anyone stroking the 6.4? If that's the case, stroking a 5.7 past 400ci shouldn't be a big deal...?

You can bore it...you can stroke it...or you can get real, and bolt on a Procharger and get 100... take it to the bank HP.

Who makes a forged kit to take a 345 to 427? And how much?

Thanks!

What kind of HP and torque are you getting with that engine?

I seen it in the lx forum. Was for sale. I think was 7500 bucks. Had hardly no miles and built by one of our vendors, MM i think. I was going to buy it but it wouldnt make as good of a blower motor as it was built for NA.
The stroke over the bore is what made it not as good for FI from what was explained to me.

The cost to forge a 5.7 or a 410 are about the same FYI the only addianal cost is the machining of the block. Forge Pistons are about the same no matter what the size unless you are looking for something custom.
