hi...can i ask you for some info since you sead you run a blowthrou carb

You mean hydraulic lifter preload ? Just making sure as some call it the same and some don’t.

Btw: your distributor in the photos is not marine coast guard approved. It’s an automobile distributor.

O thank you god....i thout you had enough of me

so what do you think...are we going to make it work or not...you are my last chance

Yes...preload

I do preload: back off all rockers.
Starting with cyl #1 rotate engine clockwise until intake valve just about closed adjust exhaust. As you are slowly turning exh pushrod with fingers as you tighten exh rocker arm, right when pushrod resists turning, you are at 0 preload. Tighten exh rocker arm nut 1/2 turn.

For #1 intake valve, do same procedure but when it’s exhaust valve just starts to open is when to adjust the #1 intake valve’s rocker srm.

I’m sure there are many videos and better written instructions, but that’s how you do it . 1/2 turn works on all cam/lifter manufacturers stuff for american v8’s.

ok so i did it wright...what do you think is this engine going to work properly...im doing the modifications on the carb...your advice regarding my procharger...my crank pully is 7.8 and my charger pully is 3.3 inc..what do you think

Sorry I never saw your post if you still have any questions go ahead and ask .
