If its the small block chevy thats sold more units than any other engine , 260 bhp can Very easily be tuned into 350 , and that make the car VERY VERY fast . The ZT handles really well, no idea about the SD1 , as i have never driven one .
The MIGHTY BRITISH BULLDOG SPIRIT LIVES ON .

A bone stock LT1 small-block, as fitted in the current C5 'Vette, delivers 350bhp. Mine has only minor mods (Blackwing and Borla Stinger exhaust) and spits out 370. There are lots of LT1 Corvettes running 600+bhp on the street here.
I'm not sure a 350ci Bow-Tie would fit in that little MG - as stated earlier, more likely to be a 4.6L Rustang engine - Cobra variety with a blower, so not too shabby at all.
