i bought my 94 cobra with 80k for 6500. those sound like a high priced deal to me? should be able to get a 4v cobra for 10k. it maybe more to mod but the block wont break on you at 500hp . some good rods/pistons you can make a killing amount of power with a blower or turbo. with all the stock cams and such. not fuel system but the rest your good to go
