Im a really big guy - 5'11'' 302lbs (135kg) beast and had to choose a chassis carefully for me to fit in. Check this link where I am seated in car;
http://www.lotus7.co.nz/forum/viewtopic ... 0&start=60 and enough leg space to work the floor mounted pedal box.
First of all, my discharge end does not fit into those silly rigid narrow bucket seats, so I decided on proper seats that are also fully adjustable and wide enough for my stern
(530mm or 21" wide seats and narrow tunnel). Furthermore, since Im decided on a 3SGTE power unit, I also needed space upfront for that and yours truly despise any form of scoop or power bulge on a bonnet.
In the end I decided on the McSorly 442E chassis. As mentioned in the posts thus far is true that the 442 is 4" wider, 4" longer and 2" taller than the book chassis. That said, no one mentioned the fact that their are two versions of 442 and very different to each other.
The difference between the 442 and 442E are as follows over and above the book chassis ignoring the 4" width and 2" taller additions;
442 - The 4" length was added to the cockpit compartment of the chassis and the standard engine compartment length and nose width retained.
442E - The cockpit standard length to book one and the extra 4" length added to engine compartment and the nose made 3" wider which makes for a large engine compartment that will even take some V8's with ease
