I finished playing with the heads and there getting surfaced and valve job so I can ck the combustion chambers cc's.I did not move much metal in there .so I hope we don't have to cut much . Ill cc them and mock it up to ck the intake alignment angels .It should not be to far because we only cut the deck 10 and the worst head was 6 out so should be about 10 there .The heads dont look like they been cut much. I hope I don't have to cut the heads intake surface I am waiting on the whipple Intake now.He was putting a special kit to gether with the bigger innercooler and leaving out the fuel system and no fuel cooler stuff. I was told they may be some work that needs to be done to the runners on it. sometimes the casting is ruff?will see

I am going to re flow them to see what difference it made But the special valve job that Mark at Precision Marine does should make some difference also. Its a special cuter he has special made for him

i have some more picks of the heads i ll post , the exhaust and combustion chambers was mirror finished

Wow----your engines echo many of the same kind of multiple issues my engines had when they came back from a careless builder I trusted in Charlotte, NC this past year. Lot's of things done cheaply, and carelessly just to get them out the door. When the decks on my engines were cut to zero deck heigth the head gaskets were beginning to leak into the cylinders because the turkey who square decked the blocks cut them too roughly. I had to have the decks recut to correct this and by that time the pistons were sticking out above the decks by 3-4 thousandths. We now have to use a thicker Ferrea head gasket. They also installed too small of a head gasket on each bank of each block. My rods weren't reconditioned at all as I was told they were and all of the small ends were out of round and some of the rods were galled-----they were assembled that way!!! No balancing either. The list goes on and on. My engines were done by some guys who say they DOUBLE and TRIPPLE check everything before it goes out the door to make sure everything is right. Anyway, it's a good thing that you pulled them down when you did. Heck, I didn't even get my engines in the boat---but then it's a good thing that I didn't because the way they were built they wouldn't have lasted long at all. Thankfully, I caught it all before I installed my engines in the boat---whew! Like you, I found several suprises, and had to have corrective action done on several of the machine steps that were either done or supposedly done by these guys. What a fippin' joke!

Anyway, it sounds like you;re on the right track and headed in the right direction with your engines now. At least you can have peace of mind in knowing exactly what you have now, and how things were done. Try and have fun this summer!

Kaama- you don't understand. The engine builder DID double and triple check everything before the motors went out the door. They double and triple checked that the check or credit card were good!

Well I am making some head way now . Waiting on the maching shop and ordered a new Dial Bore gage piston sleave installer. etc . Just waiting Whipples came in so I can ck the intake face angle before we put the head together.Also be waiting on Crane lifters since Nov 1st just got then on the 15th of Feb



Oil galley plugs . The motor came with 2 with holes in it for oiling the timming chain, some say leave it out with the new style chain , I put just one in , figured with the new style oil pump and being a HV should be ok?

The block honed out good no low spots and came up with a .0065 piston to wall clearance . I gaped the top ring at .025 and the 2nd at .030.

Crank

Installed the cam straight up which is 107.I am using the cloyds hex a just , it made degreeing the cam real easy.Ck out the piston stop I made out of angle aluminum . it worked out pretty good . I had bought one from Tivia and when you hit the stop it would flex.This one is stiff.

I bought the Crane 168741 it is one step above the factory cam which is a 169621

The 741 cam #'s are 610-632 lift and 236-244 dur. cut on a 112 and it has 16 degrees of over lap . I am kinda of worried about that.Maybe be better on the pump gas?. the stock cam has 7 degree of overlap.A custom cam would of been better Bob RMBuilder said where leaving some HP on the table .But where going to be pushing it on the outdrives anyway .

This is the new style cam retaining plate .Looks like its a polished stainless steel piece . The cam had .0055 end play with the timing gear installed.
