which built motor?
 

I stuck between dynosty, Full blown, or accelerated to build my motor. My goal is 600hp-700hp which ever this efr7064 can produce. I've spoken to all three shops and they were helpful in explaining the break down of how they build their motors. I'm leaning towards full blown because they have the most motors sold on here an no problems reported. Also they have a company that deals with the piston design our cars came with. Plus there turn around time is reasonable.

You know what my vote will be lol Full Blowners FTW!!! Customer service and quality

Full blown has them on shelf so you wont have to wait for a build. Should be good for your goals.

Call them!

I'm Interested to hear dynosty and accelerated response on built motors because they haven't talked about them on the forums much.

FullBlown. Publicly proven and readily available.

Well I've spoken to all three over the phone. And full blown was the only one to mention that pauter rods are a bit on the heavy side. And if the motor was not balanced correctly then you would have major problems. Also they explained the bearings failing deal to me. What makes them fail and how it doesn't matter if you put different bearings or race bearings. If you get a bad tune and things are not measured and balanced correctly then bearings will fail and other things causing the motor to fail.

How much is full blown charging for their motors? is it a shortblock or longblock?

$2995 short block. $1700-$1900 for heads valves, springs and ported. Does not include the shipping fees which is $200-$400 depending on where you live.

Found the thread about built engines.

Still wonder what core charge is?


Would you mind explaining? Share the knowledge. Am I to understand, that whether OE rod bearings or ACL, the inherent motor design or lack of oil will still cause bearing damage?

@cf6mech How are your ACL race bearings holding up?

Ah cool, just found their post with the price. $2995 + core for the shortblock. So i'm guessing 4500-5000+core for longblock.

$2000 short block core charge I think. I think full blown can explain the bearings issue. Don't want to explain anything wrong.

@FullBlown

There are too many variable to what could cause bearing failure. Here are some..

-improper bearing clearance
-wrong weight oil for bearing clearances
-thermal breakdown of the oil
-unbalance rotating assembly
-motor not up to temp before heavy load
-detonation

Im sure there are more issues that could cause bearing failure. A properly tuned/built motor, should not have bearing to crank contact. A crank should glide between the clearance of the oil pressure, and never ride the bearing.

You can take any high end bearing in the world and pound them out with detonation. If you ignite the fuel and maximum cylinder pressure happens at or near TDC. It will force the rod down, and squish the oil out and wear/flatten the bearing.

A higher grade bearing will withstand that abuse longer but, its only a bandaid for the disaster that is coming if you do not address the actual problem.

Keep in mind, Oem bearings are alot better than they were years ago. We have ran oem bearings in many different platforms. I'm not saying that they are identical in quality to other makes but I wouldn't be quick to blame the OEM bearings.

ACL will eventually make a drop in bearing and we will more than likely use them but until then... We just don't feel the need to experiment with other bearings that weren't made for this motor.

@FullBlown what oil do you guys run/recommend ?
