hey guys.. i was just wondering what your take is on the new crower stroker kits?? as you know there are 2.. one that handles up too 650hp and the other over 650 (econo and pro if you will).. i think the diffirences are in the rods.. anyways as you know a certain vendor (gruppe-s) is having a group buy on a short block that is capable to handle 650hp.. not a bad deal for $2700 (with your block halves in trade).. seems like a nicely built motor too.. there is another certain vendor that is selling the crower pro kits for around $2800 and econo for around $2600.. seems prety good considering you are getting a beastly crankshaft, rods, pistons etc.. i do realize in the long run the stroker kit would be more due to misc parts and gaskets and pumps etc.. but would it be worth it?? so i ask you guys would you chose the crower kit (either econo or pro) or gruppe-s' 650 block or other.. please explain why.. thanks guys

ps whats your take on the crower stage 2 cams?? (less than $500 for the whole set)

personally I wouldnt by squat from Gruppe-s. I would go with a crawford block with the cosworth heads...

Personally, I would just get a Cobb Tuner series shortblock for $2300 (no core trade required!). Our motors are incredibly stout except for the pistons. The stock crank and rods are forged. Honestly, we just need to replace the pistons and have the motor assembled correctly by top notch people. The Cobb Tuner series shortblock meets that. Plus, you get to keep your original block.

^^^ i think thats sounds like a pretty good idea too.


if you dont want to do that i would go with gruppe-s block (and def not crawford).

Do you work for Cobb?

No. I just believe that since our cranks and rods are already capable of supporting BIG power, there is no need to replace these while operating in the 500whp range. However, forged pistons are necessary. So, a stock shortblock with forged pistons is the ticket for not spending more money than you need to. Moreover, a company that can assemble a shortblock VERY well and has a very good reputation for doing so is also needed. IMHO, that is the key here. So, what company would you trust to assemble a shortblock and why? I wouldn't trust Crawford with anything after seeing what they did to BruceChapman.

durrrrr... sorry man, the way your post was worded made me think you were saying "our crank and rods" like you were speaking for Cobb's engines.



Are our engine special in some way? Are special tools required to assemble them or do so many people go with tuner shortblocks mainly out of convenience? Personally, I'd rather build it myself.

^^^ if you have the experience to build your own then thats awesome. but for someone like me who doesn't know the first thing about engine building i would certainly want someone who knows what the hell they are doing to properly build my engine. I don't want it to become a $2k+ paper weight.

I've helped friends build their engines. It's not rocket science, but I wouldn't say I have a lot of experience. Have a service manual handy, pay very careful attention to torque specs and tolerances, and you'll come out ok.

For the price of some of the tuner blocks it almost seems like buying a built shortblock is a more efficient route. But if you have the time, the only way to learn is by doing it yourself.

My buddy has an axxis stage 2 short block hes running an fp green on with c16 gas. Has had it for over 2k miles. No complaints from him yet.
Im not going to comment on any of the other companies mentioned since I do not have first hand experience or know anyone with them. It seems to me like my friend got a nice engine,

I heard that AMR Performance is comming out with there own shortblocks. Everything from 2.5L to 2.8. Maybe even bigger im not sure. I have all of there parts on my car right now. There pricing is really good so I think they are going to be very competitive. Knowing what I know now from having there parts on my car, im most likely gonna save up for one of there engines.

[InfamousDX]

Gruppe-S.

i thinkt he other options are great too - axis, cobb, world one, i guess crawford.

Is AMR really doing their own blocks or just using Crawford's?

I think it'd be pretty cool to get a nice, round 3.0. But I'm not entirely sure how realistic that is.

It is very nice that we have so many options though. Hopefully they'll all be around in four years when I'm ready for a better bottom end.

thanks for the feedback guys.. i guess that i assumed you guys would lean towards the strokerkit.. thats all you hear in the v8 world.. if your car has a stroker kit then its automaticly bad ass.. wasnt sure if that would apply here..

I'd have a shortblock built and go to closed deck if you're going to spend the money. Get it balanced to like 9000rpm. If you're gonna go through the trouble, you might as well build something special.
