440 kit qestions

[TRX01]

ok well my engine took a dump and now it needs a rebuild and i planned on doing a 416 with stage 2 cam.....well as of tonight my dad informs me that he wants to do a 440 kit stage 2 cam, new vavles and HD studs. and HD cam chain, timming chain watever u wanna call it

anyways to get to my question wat are some of the threats i need to be worried about with a 440 kit, like i no cooling would be a problem area so i got that in mind....watelse are somethings that can go wrong and make it fail:confused:

sounds like you have a good plan of attack. main concerns would be head gaskets blowing from head studs pulling. other than that you should have the bases covered from the list that you have. steve

you really need to think about compression thats really the root of reliability

its going to be 11:1

I have had a Wiseco 440 kit with a Cometic gasket on for a year and have had no problems with it.

thnaks man

i also recommend getting a 3 piece headgasket from cometic. they are really nice and probably have the least chance of blowing. steve

id go stage 3 cam on that motor and 12:1 it will still run on pump gas with the stage 3 cam...if installing the HD studs i would also have the head and jug milled .005 inch on both total of .010 inch overall....now this will run on 91 octane at sea level....so if your higher then sea level i would still use 91 but if over 3000 id use 89....the 12:1 will be changed to 12.55:1 but dynamic compression will be 10.15:1.....so with that said you would have a higher hp motor and still run her on pump gas....OR still mill the jug and head to give a fresh flat surface for the head gasket and double up the base gasket to take the 12.55:1 back to 12:1 and run her on 89 at sea level....either way id go witht he stage 3 motor...the stage 2 cam is a minimum cam to flow the 440 motor...the stage 3 just does a better job filling the cylinder and is no harder on the valve train then the stage 2 and in reality its easier on the valve train because the nose is more rounded on the stage 3 where as on the stage 2 its more peaky do relitvly the same lift but shorter duration....justa suggestions parts are the same price might as well get your moneys worthe
