How do you put a Chevy 720 crate engine with fuel injection into a 1979 Chevrolet Monte Carlo?

Answer 1

Well you must do the following things. one if it is a V6 car you must move the motor mounts forward one bolt hole. If it is already a V8 thine you can use the mounts you have. the front suspension will have to be upgraded to a heave front set of springs and a good set of adjustable shocks. now for the fuel inj part. you will have to one replace the gas tank with a unit that is going to have a in tank pump. Cause the one you have now is on the block and is meant to pull not push like the ones for fuel inj. or you can convert to a fuel cell with an in tank pump just call summit or jegs they can steer you in the right direction if they don't have them. You'll have to run a new fuel line also cause the stock line is two small, i suggest at the least a 3/8 line but a 5/8 would be the best. Now you will need all the wiring and ecm's to run the fuel inj. and the knock sensors and all the other electrical components on the motor. you will need atleast a 400 turbo to hold up to the the beast cause of the torque this will put out. The best thing to do is convert over to a floor shifter it is an easy install. You will need to get a custom cross member for the true dual exhaust and headers. I used a cross member from a 66 Chevelle cause it has the double humps in it for the duals. But you have to measure your width of the car and the cross member and cut one end and flatten that end back and drill to new holes for the bolts. Then rempount it. The driveshaft will work with no mods. The headers are your biggest problem. you will more than likely have to have a custom set of headers made at any good exhaust shop. The last thing you will want to do is upgrade to one a bigger rear end or just improve what you have. The one you have is a 7.5 w/26 spline axles. It is the same as the early 80's camaro's and even S-10's, can get the ring and pinion from a junk yard real cheap or buy new. I am running a BLOWN 406 84 MONTE CARLO. Making a conservetive 580lbsft of torque at the wheels and 685 hp at the wheels all to just play around with and haven't had any problems with a stock rear suspension with just an air bag in the passenger rear spring and a rubber block in the front driver spring and i lift the tires 2-3 feet and carry for about 5 feet with 1.4 second sixty foots all on stock components with a stud girdle pan and 3.73 posi. well i hope all this gets you going in the right direction and good luck.
