360 build

To make 350 hp is easy. You dont need 9.5 to 1 compression. Just had your heads milled .010 to clean up and use a steel shim head gasket thats .020 thick. That will yield you 8.5 to 1 and that is all you need!!!! I would run more cam, say a comp XE270. This combo will scream! Dont over think this and waste money on things you dont need. This motor will be a tire smoker. Again just so were clear, dont change the pistons you dont need the extra compression to get the goal of 350hp. Its very expensive and not necessary.
