How would you build a low 10’s street car

Well a turbo is not a bad idea but this is another way>
Friend of mine here runs a street '72 Demon, mild 416, iron heads, 3.55's, 8.3/4", hyd. cam, 3500stall, 275 d/radials (26" tall), SS/springs, chassis ties, air-gap, 750DP. Car weighs in the region of 3350 all in. Has run a best of 11.6@114, makes around 400fwhp. If you built a similar [email protected]>10:1 from your 340 but with TF190 heads and a mild solid cam, you could get that up to an easy 450+hp more so near the 500's which would be low 11's@that weight. If you then bolted on an on demand N20 kit and used a good clean tune, a 150hp shot which is quite safe could get you 1 sec off and put you in the low 10's@around 10.1>2's@132 with slicks of course and good shocks. Wouldn't cost a fortune and it would be streetable and still drive ok with a sb with those 3.55's and taller street tyres....my2c's.
