Sorry guys, It still ran the same.
I went from 5.895@117 to 5.923 all weekend at Pacemakers. I runner upped on Sunday (took 7 rounds and only paid $200r/u 800 win), but it makes me feel silly to have a bbc dragster that runs 5.90's
I think the compression is lower than I thought...
I have world merlin 320 runner heads with 119 cc chambers and a trw pistons with a .580 dome. The pistons had to have .090 cut off for piston to valve clearance with the big 2.300 valves.
I really just dont understand it, my $2000 flat top 406 with a flat tappet cam is faster than this 468 with pop up pistons and a .722 roller...
Wow, I guess I must need a new shortblock?
I had the timing at 36 degrees then bumped it up to 42 and it popped, is 36 a good place to start.
