tell me your 440 combo

Most likely yes most any big block head with some porting will get you 400hp thats a pretty low number for a 440 should be very easy to build a 400hp 440. But i have to agree with gtx if your goal is only around 400hp find a cheap 360 and start from there. 360s will also fairly easily get you 400 hp not as easy as a 440 but all the extra weight will hurt you. A nicely rebuilt 360 with a well chosen cam, intake, carb, headers etc will put you right about where you want to be and make it more driveable and honestly faster than an equal output big block just because of the weight savings Good Luck whichever way you go Justin
