91+ octane

850-950 Holley (does not need aftermarket Holley type)
Dart Oval Intake (Vic Jr oval fine too)
265-290cc AFR's (depends on pocket $$$)
230/236 .600 lift 112LSA (could push this a little further if he wants) 4-5 degrees advanced
Lightning Headers (or Stainless marines) - either with water dumps far back towards tails
V6 module for Tbolt IV or External Coil HEI (the EFI one but without using EFI controls)

bfsc,s .i don,t really pay much attention to them now that we have a/f ratio measurements at our disposal.before we had a/f ratio on the dyno we paid more attention to egt,s and bfsc,s.on another note,it is common practice to prop a boat above max hp rpm and the boat will almost always go faster that way.

lol I like to hear all the info.

ok guys..ive changed my mind on my motor.ive have decided to go with a 540CI.for the budget thing.....go big I guess lol.I have a guy building my motor.he builds drag cars but he has done boats also.going with a merlin block and im not sure what heads yet.i have to find out what he has in mind.he is into using good parts.block,crank,rods and pistons.4,800 bucks so far.

ive looked at a lot of exhausts. a lot of them are rated for HP.whats the best for like 500-700 HP?

Stainless marine or if you can find some, keith eickert cast headers. Brings all the benefits of a header without the leaks. Only real drawback for some is they don't prefer the asthetics. To each their own.
