What heads do you think
I am building a 454. I am going to use the same pistons as the 525 sc and the same super charger. I am looking at the Dart iron 308 and the Dart Iron 345. What do youll recommend. I am trying to make about 600 hp. I am putting these motors in a 1999 Forumla Fasttech. This boat was a race boat so I am seeing what it will take to hit 85 to 90 mph.

I saw a post the otherday that somebody had an intercooler for the 177 for sale. I have been reading up on this thinking about eventually doing a 525sc clone when its motor time. From what I have learned the 177's make a lot of heat as the boost goes up. The other option would be to use a little bigger blower. The 177s do make a nice whine when you have them spinning

600HP will get you right at 85-91.... If your 353 has the gutted interior/light weight should do better ...... best I have seen this summer is 94mph not even pushing it hard ....Holley EFI shows 66% max throttle ...m
