Motor had good compression - 150 on all 4 prior to tear down. installed head gasket & almost new 264's and mudd. 4-3-2-1 is 80-130-80-130.
Lifters are original - 160k - are they taking a dump with these cams?
The car runs like crap. IT IS IN PERFECT TIME. With a general tune today through 3rd gear - no knock - was smooth however it just felt like it was holding back timing. I had 2g maf installed which we thought was the culprit - but after putting 1g maf back on it still sucks. Really rough idle. I had to turn out biss to get the thing to idle. Car has 780's, 255, 14b @ 15psi. #2 spark plug stays black with 2g maf - but the cylinder is dry - so we don't think it's blow-by. ??? Haven't checked the plug since 1g maf went back on.
There's a lot of variables here. I know it needs a proper tune - an afpr would be nice - etc etc etc...
Gonna try swapping lifters between cylinders to see if compression changes also. So you know we've run similar setups and been successful in the past. A little upsetting after seeing that compression...
