A 4.75L stroker kit doesn't add enough displacement to make the exercise worthwhile IMO.
OTOH, a 5.0L stroker kit with a 3.80" stroke crank and 3.554" pistons (+0.002") would yield a true 302ci.

 

I've looked into going with a new reciprocating assembly a few times. My thoughts were that the biggest advantage of it would be the forged crank, rods, pistons giving you a good solid base to build on. If you don't want to force feed it you can go with a lot of squeeze in the chamber by choosing the right piston. The longer stroke and larger hole will help facilitate this without hanging such a large chunk of aluminum out the cylinder. Mmr was one of the shops I was considering to buy parts from. There are others. It's actually cheaper to let them build it. But that just goes against my grain. And I've heard mixed results about the delivered product from some of these shops. Research carefully

 

MMR... good luck with that.

 

Lol MMR... the only thing they can build are dildos. Big, forged, aluminum dildos that will **** you over

 

:lol::lol::lol:

 

Dang!

 

I was going to say something but I hate bad mouthing. Mom always said "If you don't have nothing nice to say, don't say anything at all." But I would steer clear of MMR. It's not that they have an issues with parts really, but I would just steer clear. Plenty of other places to get parts from.

A 3.75 with a 20 overbore should net you right around 302 cubes. Kellogg crank and pistons of your choice.

 

Why not a saleen assembly? Theyre fairly cheap from what I've seen, rods look beefy, and youll hit 302CI.

 

Brenspeed blocks are pretty good (B302) they use the Saleen tooling on them or the FRPP 46x were my choices but went with a stock block and all forged internals. You could do a 298 or 302 stoker.

 

You guys make me laugh, as im sure 90% of you havent bought or used anything from mmr.

I would be buying a rotating assembly not a short block. I wpuld assemble the engine myself. The last rotating assembly i bought from them was all manley parts anyways. I have heard horror storys of there own assembled engines. I want no part of that nonsense.


I was only curious to the 4.75 stroker engine they claim. Was curious about the crank.

Who sells a 5.0 stroker rotating assembly kit?

 

I am running the coast high performance 302 stroker rotating assembly in my .020 over stock block. 707 HP turbo and runs great. Wish I had gone with tool steel wrist pins though for future crazy HP.

 

There is a reason none of us would own parts from MMR.

 

I would by name brand parts from them. Manley Pistons, Kellogg crank and stuff like that. I wouldn't count on much for customer service or ever have then build anything for me, but off the shelf parts shouldn't be an issue if they have the better pricing.

 

Ok. Well who makes a good 5.0 crank for these mod motors

 

Eagle or SCAT is an economical choice since Kellogg is no longer making mod motor crankshafts. I would have whatever rotating assembly you get balanced and it should last as long as a Kellogg.

Now if you want a high end billet crank, there's numerous choices.

 

I don't have the funds for it right now, but I've been looking up info on stroker kits. This one seems like a good bundle:

Eagle 302 Stroker Kit for your 2005-2010 Mustang GT

LethalPerformance has some kits too.

 

Eagle = China I think? May be wrong though

 

You definitely want a forged crank with a stroke of 3.750" or 3.800" to reach 5.0L of displacement. I ran a 3.750" crank and 3.700" pistons in my Boss block to achieve 322ci or 5.3L.

I believe Livernois still offers a forged stroker crank, that's where I got mine from.

 

I dont think i wanna go 5.3 doesnt seem like itll last long in my head lol

 

You could go for a Brenspeed 326 stroker short block. It's based on the Boss iron block and should be bombproof.

 

Like 100k miles of semi abuse bombproof?

 

Yup. I know of at least a couple of guys who are reliably running B326 short blocks with over 600rwhp so have no fear.
