430 valve lash specs solids

[rttnrandy]

I am tring to find the valve lash specs for the 430, this is in a chris craft just rebuilt the motor can only find for hyd not solid is it 19 and 19

You start with the recommendation of the cam manufacturer. There were no solid MEL applications OEM.

this is a 1960 stock chris craft ,the cam manufacture was lincoln it has gear to gear drive no timing chain, it has never been touched unless possibly by chris craft this was a one owner boat. restoring so did not want to change ,had the cam reground ,so they should know what they ground it to.

The solid lifter application was OEM in the Chris Craft 430... I will look it up for you. Give me a day or so.

thank u

Valve clearance (lash) - engine hot .025 exhaust and intake
Valve clearance (lash)- engine cold .023-.027 intake

This is from the Chris Craft 431 manual reprint #3 June 1967
The 430 in marine application always had solid lifters to my knowledge, but I checked this to be sure in this reprint... answer is yes.

thank you very much,one other thing in the casting on the intake it looks as though the firing order numbers had been chiseled off ,but the word firing order is still very much intact, was there ever any change by cc due to the solids 15426378 is what i got out of a 60s motor manual Thank you once again for the correct specs

The firing order changes based on the rotation of the engine. You have either a RH rotation, or a LH rotating engine. You mentioned a gear to gear timing set up, so you have a RH rotating engine. Keep in mind this is an engine with the flywheel at the front, so a RH rotation engine is running counter clockwise.

I also found the valve adjustment sequence for your solids

Standard rotation engine

With Number 7 cylinder at top dead center, in firing position, the following valves may be adjusted:
Exhaust: 7-1-8 Intake: 7-4-2

Crank engine 180 degrees, this is Number 1 firing position, following valves may be adjusted
Exhaust: 5-6 Intake: 1-8

Crank the engine 3/4 of a turn, 270 degrees, This is Number 3 firing position. The following valves may be adjusted
Exhaust: 3-4-2 Intake: 5-3-6

In this the flywheel is actually in the rear of the engine,is was put in like a vdrive,but the velvet drive connects to the front of the engine on the crankshaft on a big splined dampner,thanks so much for correct sequence

[rttnrandy]

finally figured this out on this motor but still do not know the firing order, took me a min to under stand the right hand -counter clockwise , a chain would turn the same way but gear to gear is rh cc, was there a manual i could buy for this motor application from chris craft
