440 HP Estimate

Hello All,

I have been deciding between a BB and a SB Duster.

Here is what I have for the BB:

Mid 70's 440

452 Heads with a valve job

It will get a rering kit and be run as is. Cylinders look good but I have not mic'd them yet.

Intended build:

Bigger Summit cam and appropriate springs

Template port the heads

.020 gaskets

Stock intake for now

Hooker 1 7/8" headers-fenderwwells

I realize that the compression will be lower than desired but it will have to work for this year.

Fairly stripped 74 Duster with 4.10's.

Any ideas on Horsepower/Et's with this combo? I may be able to spring for a cheap convertor.

Thanks, ROB
