I'm glad Ryan stopped running the engine when he did because the #8 exhaust lifter was about to fail just like the other engine. Blocks have been cleaned up and being honed. Ryan said there is a lot of variation in the sizes of the cylinders. Got the new heads from afr & Ryan is going through them to make sure everything is right. I see the Sultan of Silicone is advertising again.

Who is Ryan - is he building your engines now ?

I'll say it again anytime you see a marine engine builder and or a marine tech using silicone on engine parts or even on the outdrives , its a builder and tech you want to stay away from completely. In the industry they are called shadetrees.

Well if that's true then Bullet Engines must be shade tree.

hAVE TO WOUNDER IF IT WAS RUN ON A dYNO IF A BREAK IN WAS DONE before making power runs. Have seen many engines blow doing power runs without a 5 to 8 hour break in soon after installing in a vehicle. Some with only a few hrs or minits after first use.
Rockers I always used Crane gold rockers didnt know they made blue except ones Crane made for Ford Motorsports. uhjyjjy76 < my cats thoughts on this thik she just cussed out the builder.

If you read the thread this is about two engines that have been in my boat and ran for 2 seasons. The person building the engines now is "Precision" on here. Retter Engine Development, the original builder was Bullet Engines in Kingston Ontario.

Silly question but why have so many manf in the valve train..ive always had great luck with crower and there tech line is great. They will grind anything you want and there roller rockers are great...just my .02

Break in is basically up to temp on a full roller engine... If it's built right it will he fine.... Break in is a thing of the past bud...

im in the middle of my first marine build but i agree with full force. on my mustangs i run them for 3-5 minutes to check for leaks, then i make 3 full 1-4 gear pulls wide open. as little run time as possible at idle. try to hold them around 1500 until i can WOT. they are either right or theyre not. i want to know fast. i treat the isx, m11, B, C, L, N14 cummins engines the same way.

I just found this thread.... i am surprised they ran 100 hours with no issues... Bullet engine seems to be a very unreliable engine builder.. It blows my mind how these guys stay in business!!!!!! I hope people read these threads!!!!

some of the pushrods were 3/16" of the roller rockers on 2 engines he did for me!!!!
