The motor started life as a 1984 3.5l SD1 which gives out 155 as standard. Then for the rebuild I retained the original pistons as they are work hardened so stronger than new "green castings. The bores were honed and new rings fitted. The crank was reground with all new bearings. A piper 270 cam was fitted with an adjustable vernier timing wheel and the cam timing was adjusted to suit the cam. The heads from the original engine had already had some work done but I re seated the original valves. My only regret was not replacing the valve guides. Inside the head ports you could see the valves had waisted stems and the valve guides had been cut right back to remove them rom the air stream completely. The block and heads were skimmed very slightly and composite gaskets were used so as not to increase the compression. A brand new Edelbrock performer inlet manifold and carb were fitted and I blueprinted the inlet to the heads. A Mallory unilite distributor was next with a Hyfire 6 CDI unit and promaster coil to give a big fat juicy spark. Obviously in a wedge it has tubular exhaust manifolds.
I must confess I was surprised at how high the reading came out but Alan Jeffries assured me that their machine was accurate so I'm grinning. If I get the chance I will put it on another machine to campare it.<blockquote id="quote"><font size="1" face="Century Gothic, Verdana, Arial, Helvetica" id="quote">quote:<hr height="1" noshade id="quote"><i>Originally posted by paul w</i>
Awsome Sam,i cant believe how much hp you got from a carbed 3.5
What mods did you say that engine has?
In comparison,my 4.6 is supposed to put out 260 at the flywheel,i recently
re jetted and rodded it (careful now) and have yet to get it back on the
dyno to see how much xtra its gained.
Looks like i need to stage three it to beat ya now!!
See ya. Paul

If it doesn't fit you obviously need a bigger hammer.
