i wrote early in this post that i knew a guy who bought a complete motor from dynoflo last season...i think it was a 565...after 3-4 passes i saw it being towed back to the pits...he told me something went wrong and dyno flo told him to ship it back and they were going to fix it...well i saw him this saturday at the track for the first time this season and i asked him what happened on the deal....
he stated after 3 passes the 3 bolts that hold the timing gear sheared off the camshaft.he spoke to scott at dynoflow and scott agreed to have it shipped back and repaired.....dyno flow allegedly repaired the motor and shipped it back to my freind...scott stated that they were using a new experimental form of loctite and it was failing and had failed in several other motors.
my freind puts the motor back in and makes a few passes and she runs like crap.he pulled the motor and brought it to a local shop.the local shop found the pistons were pretty banged up and she had 4 bent valves and all the valve guides were wiped.....so what dynoflow did is repaired the cam/timing chain problem but didnt inspect or repair any of the resulting damage....
my freind then decided it would be best to disassemble the whole motor and check everything...basically what they found was that every item that dyno flow said was in the motor was...it had all the good parts that were supposed to be in her...but all the clearances were just wack...they said what they found was if someone purchased all the good parts and then just slapped it together with no regards for clearances,tolerances etc...
my freind stated that dynoflow puts the motor together with top notch parts,the price is very good but the assembly and machine work[if any is done at all] is horrendous.after all was said and done,my freind said with all the money he had invested in the motor buying it and then having someone else fix all the problems,he could have bought an excellent piece from like reher-morrison.
you would think with this poor quality workmanship that this would have caught up to them by now...hopefully spreading the word in this manner it will soon.
