[85monte_ss]

can someone explain what is all needed and how mch of a b*tch it is to put it in a monte carlo keeping the a/c and p/s if anyone has done this and is it worth doing i have a good running sbc in it now and i want to do a mild bbc for cruising and use the sbc in a drag truck please message me with any tips or info thanks

it can be done but good luck getting the p/s valve cover off if they are any taller than stock. Everything else will just bolt in, you will have to change the rear end though to handle the power of the bbc

i already have a 8.5 10 bolt in it with the small block it runs 11.70 on pumpgas

will a big block fit with that HUGE a/c box in the engine bay?

yes but you cant remove the valve covers
