I am currently collecting parts to build a 493 stroker. Wondering what people's opinion is on the route I'm thinking of going. Was planning a 440 build and was about to order parts but a freshly machined 493 block came up for sale so plans changed. Currently I have 99% of parts for short block. Freshly machined 493 block Eagle forged 4.150 stroker crack Eagle beam h conrods Diamond pistons (domed) 917 deep sump Custom headers (2" primary into 3.5" pipe work) Msd billet dizzy, ss blast coil and 6al box I am thinking of of going with a trick flow top end kit (Trick Flow® PowerPort® Top-End Engine Kits for Big Block Mopar 440 TFS-K616-620-576) Holley sniper X efi system Things I am unsure on is A. Is it worth installing a 440 source gridle B. Weather to go for a mechanical or electrical high flow water pump C. To use the trick flow high rise manifold (comes with top end kit) or use torker 2 manifold that I have.
