400 stroker - 10/13/17 01:29 PM
Will be building my 1st mopar stroker engine this winter and would like some input. Will be using a 400 block, 440 source heads that have been reworked and flow:
Head flow numbers
100 lift 77cfm
200lift 161cfm
300lift 230cfm
400lift 271cfm
500lift 283cfm
600lift 287cfm
700lift 285cfm
Engine will be going in a 3200 lb car with driver and hoping to get to the 6.2s-6.4s range in the 1/8. Not looking to turn a bunch of rpm, would like to shift around 6000 and not twist it over 6500. Looking to be around 10.5:1 compression. For the moment will probably stay with a mechanical flat tappet camshaft. My questions are:
What are the pro/cons of the 512/500/470 kits?
Obviously more cubic, but would one be better suited than the other for what I'm trying to do?
As far as block prep:
Should the block be atleast partial filled?
Do I need just main studs or main studs and a girdle or go ahead and get 440 source main caps with studs and girdle?
Any other helpful tips and suggestions are appreciated. Thanks.
