4.310" bore and 7" stroke for a farmall 450, with 11:1 compression and a few "add ons".
Would the "add ons" be a cam and roller rockers?
Would this engine happen to use billet rods?
Why don't you ask the guy putting the package together what the power should be.
Then again, engine RPM, carb modifications, and head modifications can have a major impact on an engine when you get that big.
I would guess 90 hp if you keep the carb and head stock.
I believe the seller of the parts has said that his customers have seen better than 110 hp with the right setup.
