i have a 35 plymouth coupe with a low compression 413 big block kind of rat reddish hot rod car, its got a fully boxed frame roll cage 727 trans ford 9 rear tubbed 16.5 inch wide tires.. the point is I'm building a 440 aluminum heads forged flat tops that brings it to 11 to 1 compression or a touch higher, solid lift 570 duration cam, roller rockers, tunnel ram with 2 holly 4 barrels a 3500 stall converter holly blue pump, high volume oil pump and other odds and ends, when i finish the motor up and put it in the car around how much horse power do you think it will make? just curious

here is a note that might or might not be important. if the trans is a 1965 or older, which if it is from a 413 it will be, the trans does have a rear pump. meaning it can be push started. the 1965 was the last year a 727 had a rear pump. in cars. they did use 413 in motor homes in to the 70s the last year , iam not sure. but the motor home 413 had lower compression. my dad put the motor homes pistons in a 1965 413 bolt in, but not cheap, balance is same. CR goes from 10:1 to 7.5:1. still ran fast, on low octane
