Is this chassis too small???

I live in Matlock-Bath, Derbyshire.
I'm on the PPC mag forum alot(i think i'm the 2nd highest poster on there!!)
Betweeen me and my dad we have a vast collection of cars/projects, from Minis to a 150ton Scammell tank transporter!!(via 60's Alvis & Daimler, and a Bentley Turbo R).

I'm building a Haynes Roadster, i'm planning to use a BMW M52 2.8 engine and box. With a few tweaks to the engine(2.5 inlet manifold and larger thottle body), i should see about 220bhp

(I think i'm doing the PPC thing of thread hijacking? D'Oh!!)
