2650 is with me in it as it sits on the line. Maybe I should mention these are small chamber W5's with double quench pads, .032 piston to head.

I'd be happy with 9.70's. I also expect the track to be well prepped as this is a $100/car test session. If it's not I won't be the only unhappy camper they'll hear from I'm sure.  I'm taking jets, drill bits, a timing light and other various and assorted utilities to dial this thing in. I aint wasting my $100.

Yeah, there really isn't a lot of work in them. The chambers were opened up and the ports cleaned up really well. No CNC program or anything like that but my head porters bench is a little stingy too.

The idea was to have enough motor to run 9.70's in the heat and not have to lean on it real hard so it would live until I can get a real block.

Yeah but that 363 was 15 years old, worn out, smoked and was just an MP shortblock to start with. It was a stop gap engine to get me through the last two races of a season and to the finals. It just never missed a beat so it lived there.

And you know what? I must be retarded, the heads flow 330 @ .700 not 230. What a dolt I am. I really shouldn't drink before noon.

I knew something was wrong with that picture. I think 9.60s are a given. with a better converter you could reach 50s or better imo. oh yea say a prayer for the rear.
