Interesting thread.
Was looking at buying a couple of big spec cars with low comps, long studded, ported and polished head with a T35 and uprated cams, though I want it to be as driveable as possible and very responsive, as it will be used mainly round town.
I also want at least 400bhp to keep up with my current cars performance, so was thinking of removing T35 and fitting something like a roller T38 or GT30.
