Just remembered its a forged crank and internally ballanced. Ive changed the converter on it and theres no wieghts . werent any on the old one and none on the new one.

Im ordering a few parts for it. SSI cam and lifters from PAW 243 @.050" .508" lift 108LSA, Timing set, and gaskets. I also have a timing chain tensioner. It needs a new chain anyway. When I took the mech. pump off I stuck my finger in the hole. Man it has alot of slack in it. And ive replaced it once already.

I'm also looking at a solid cam 284 adv. 241 @.050" .527" 106LSA. My desk top dyno realy likes this cam. Nice flat torque curve. with 9:1 COMPRESSION SMALL HEADERS AND A DUAL PLANE INTAKE IT SAYS 388 HP @ 6000 AND 387FT,LBS @
I figure if it doesnt make it faster it will atleast sound nasty. :roll: :D

When I get the heads off if they sit way in the hole I'll have them milled a bit. Once I get a set of gears in it, it should move good.

Okay, there is a really good chance you have the high comp. pistons. Find out for sure before putting in a different cam. You gotta at least take the heads off this winter and find out.
