5.7 HEMI to 6.7 Stroker (Anyone?) - Dodge Challenger Forum: Challenger & SRT8 Forums

Has anyone done this? Order the block only as a base and put all your stock parts on it and build up from there over time? It seems like a reasonable plan and idea and the cost is not bad, $4,699 right now not counting core charge of 1k. The stock 5.7 parts should work on this right? I plan on doing the work myself until of course I hit a snag.

Any comments?

I imagine a 6.7 liter stroked from a 5.7 would be awfully thin after that wouldn't it? I could see some heat issues coming up.

Seems bad ass though, I love the "410" displacement

Funny, I've actually been emailing "shophemi" to coordinate to have the 5.7 to 410 stroker kit shipped internationally....(forged internals)

And yeah having a base 5.7 block bored out to 6.7 seems risky... I'll keep you guys posted on progress, but it probably wont happen for a few weeks.

Yea that seems very risky!! Why not just bullet proof the 5.7 and boost the **** out of it?

I agree, For a lot less money you can beef the lower end, drop in a cam and some heads and be at 500hp. Add a blower and eat RUSTANGS for breakfast!!!

Oh yeah, trust me, the magnacharger is coming after the stroker kit.

But seriously, that's a good point, bulletproofing the bottom of the block with a good blower/tune should net you at least 550 rwhp... then we start talking about tranny upgrades.....

Well the money it's going to cost you to stroke this motor you could do a lot of upgrades to the 5.7...the 5.7 is a very good motor any way you look at it. Like stated above, forge it, cam it, and boost it...it will be real fun! But you always need to remember, in order to get that power to the ground you need supporting trans/rear end mods along with suspension...

Oh yeah and nitrous, how could I forget about the nitrous!

But to get back to the original topic of this thread, I don't really know anyone who has upgraded to a 5.7 based 410 motor (sorry, just turbo'd imports and bmw's here in germany)....but I would imagine you would have to be real confident about those cylinder sleeves.
