I just set the engine in my first 'new' modified, Yeah!

The crank center line is about 14 inches off of the ground. Metric front, no weight turned in on the front jacks, 26.5 inch tall hoosiers. Definitely not enough hood clearance as the valve cover breathers are preventing installation/clamping of the hood, clears the old car fine. Intake and carb haven't been installed yet.

I think the centerline in my old mod was about 11-12 inches from the ground. Metric front with the exact same springs. Is the 14 inch cL the latest in technology, or a mistake? Keep in mind that this is before jacking any weight into the front.

Thanks for your input!

Is your new chassis a different brand than your old one.

Do you have the breathers in the front on a cross over deal? If i put the front one on i have to cut my hood to clear them but its under the hood scoop so you cant see it. I also have a metric car.

The older mod is a '93 D&M, the new one was built by a much lesser known manufacture (not sure how long they have been around). I see that they are putting together cars for a few of the local hot shots and claim a 2001 track championship with one of these chassis. The product looks good for the price even though I am finding that some things (shock mounts, drive shaft loop, etc.) will need to be moved around before the car is track ready. They are willing to correct anything that I am not happy with.

I am guessing on how the did this, but to describe the engine location, it looks like the stock frame was fastened to a flat plate (jig). The lower rails were then added (placed flat on the plate/jig) at a point no lower than the bottom of the stock frame.

After a few uprights were installed, a dummy bell housing attached to a motor plate was then placed on top of the flat jig to position the tabs for the motor plate. Essentially the bottom of the bell housing is flush with the lower rails of the metric subframe.

On the D&M the bellhousing dips below the bottom of the stock metric sub-frame.

The tip on hiding the breathers under the scoop is a good one. Both my breathers are on the left cover. I can whittle or hammer everything down to fit, but was a little surprised that everything would need lowering on the top side. My other alternative may be to jack up the rear of the hood. Common rules (UMP,IMCA) say max 3 inch rake with 4 inch side panels and enclose the back of the hood. Either way I am very happy to be this far along in preparation for the 2002 season.

Anyone tried this or know if other mod builders locate the bottom of the bell housing flush with the lower rails on the metric subframe?

if the shock mounts and driveshaft loop need moved sounds like the engine might not be in the correct location . back of engine may be to high.
