Thanks guys, fast Fred would you leave the two outer exaust ports stock with a mild cleanup or alter them like your port map? You just got to love those 3 cyl. OMC

[Fast Fred]

you want to move them, best to move the out side two up and out to the sides, center up with more height than the outer two. chauffeured is best, the wider the bridges the better thay stay cool = the longer she will last.

the last shot, those are them, them bein what you want yours to look like

Thanks again fast Fred, I will start on it soon. Bought the motor for parts, low compression but then I got the bug and I tore the head off and cyl. wall was nice,
might still get it bored 0.020 over to clean her up.

if you think your hull is light enuff, a set of long rods and pistons may work for you. wiscos, i run them at, the piston +.008, cuzz the pistons goin to grow .004 when i heats them up.

After tearring her down, I notice the piston port windows where work on so I got curious about how she ran when she was healthy and decided to grind the port map with out the finger ports. I got her honed and put new rings and fiber reeds in it. After waiting patiently for a pro 50 clamp bracket with no luck, I've decided to replace my running power head with this one. Now my question is, what jets should I start with?
Thanks. Mike

[Fast Fred]

show a pic of the powerhead for me, so i can see what carbs you got on her and stuff.....
