Just wanted to post a thank you and high recommendation to Mike Dawson and his crew at JD Machine in Lake Havasu.
I had an uh-oh with my motor right before christmas and told him I just wanted a strong bullet proof motor for our "Triple Sec" Campbell Cuddy Cabin 24l.
They worked with Mike Huston of Huston Marine(also did a great job and was agreat resource) and pulled the motor, tore it down to analyze the damage the week after christmas.
He came up with a full roller 468 Chevrolet combination using new and existing parts, spent a week dialing it in on the dyno (508 HP/525 TQ (avg TQ 500+)) and resolved an exhaust temperature issue that turned out to be my carb.
Motor is back in the boat as of yesterday.
I know they have built multiple other motors for Campbell owners and he listened and delivered when I just wanted a strong cruiser to keep me going up and down the lake all day long
Once again, kudos to Mike and JD Machine
