Just got a 80 malibu, it supposedly has a 355, it is a 010 block, it has 305 heads i found, mild cam, mild stall, 400 turbo transmission, and it has the stock 7.5 rearend with 3.08 gears in an open rearend, I was thinkin about throwing a mini spool in for now, it is drivin on the road but not much,i will be driving it to the track, the track opens in 2 weeks and funds are low right now, i'm not gonna run slicks, How bad of an idea is this ? is it gonna brake? How long will i get out of it??? please advise.
