454 Ho
 

My dad and i just aquired a 454 HO long block. It has the big rectangle port heads all the forged parts roller cam, etc. What can i do to this motor to get some more HP out of it. I already think i am going to get a set of aluminum heads for it. I have the same exact motor in my boat now and i may build it for a spare or for another boat. P.S. Supercharging is not an option. :cool:

Diff Cam Good Aluminum Heads And Change The Compression. Better Exhaust.

Thats what i was looking for what cam and heads would be the best to use? I already have EMI exhaust on the boat.

Pm Rm Builder For Cam Choices. Then Do A Search On Afr There Has Been Alot Of Talk About Them.

I Used The Gm Performance Heads With The 110cc And Went To 10.71:1 Comp.

I Am Sure That You Will Find More Info Than You Will Know What To Do With

I Just Did A Build On Mine Went From 330hp To Around 530hp N/a
