Aaahhh. I guess you'll be getting out the file and/or grinder to make it work. If you want to try the tall stamped steel ones your welcome to them.

Well, hit the track for the first time.

12.79 @ 118.2, 2.39 60ft. Car weighed 3526.

This was with a chip that is pretty damn close. There's a little more tweaking to be done, but not that much.

I'd love something like that in my car! How does it idle with that cam? You think my heads, bowl blended dart II's would be able to make those power levels? I know the car would be slower with the extra 350 pounds.

The car idles great at 950 rpm. I expect the compression has a good part to do with that.

The exhaust ports on the DartII's need lots of work. I wouldn't think the compression with iron heads would work well. It would take more cam to make the same kind of power, taking away from the driveability.

The best thing is that I'm pretty sure there's still some left in it. I'm going to be trying 1.6 rockers at some point. I've been fighting a PCV system that's been putting oil into the intake and leaving the plugs unreadable. After I get that in check, there might be issues with the valve guides but until I rule the PCV out I'm not worrying. With the oil problem in check there should be a couple more degree's of timing left.

This is a hell of a combination. It gets 16 mpg around town on a very conservative cruise tune, 20 + on the highway. Idles in traffic. On a 95 degree day with 90% humidity didn't get over 190 degrees. Cruises at 2000 rpm at 80, and pulls like a freight train from there.

Now all I need to do is figure out which sensor is bad so the AC will be cold. Cool

Why did you go with hypereutectic pistons instead of forged?

Is this an automatic or a standard? If an auto what converter are you running?

I went with the hypers for the weight, added strength over cast, tighter bore fit, and cost.

The car is a 6 speed.

If you don't mind me asking how much did that motor cost to put together? Parts / machine work?

What work did you have to do to the block?

Did you have to run a small base circle camshaft to clear the rods?

Is the block a two bolt or a four bolt?

Sorry for all the questions but this motor really peaks my interest.

btw...how much do you this I could sell a 350 with dart heads long block motor for?

Long block worked out to be about $4500 complete. That's everything. The intake, flywheel / clutch, injectors, exhaust, misc crap for the install added another $4000.

The block is a 4 bolt one piece roller block and the cam is a reduced base circle. The machine shop handled all of the clearancing and short block assembly.

The drivetrain cost me more than the car Surprised
