$999.95 for carb,ignition and dyno tuning.
The rockers on that engine look like a decent set made of ss and from my knowledge the clevite bearings are a good way to go

An exhaust system that allows 500HP to be realized isnt an "extra"

If you are switching from a big block to a small block like the poster inquired about the in the original question -

Where do these "extras" come from?


UD

All these things you qouted.
And I believe he has an old boat that he would probably be upgrading the exhaust too to the get 500hp.
Also I do believe the 454 and sbc mount the same

Uncle Dave

Lets keep going on the basic block-

anyone have a dyno chart with marine headers?

Mounts the same ? Do the parts suppliers think so?

500HP through what headers? what happens to HP on wet headers? ..... lets go back to the specs..

"CNC Hydraulic Roller camshaft"- ??!??! whats the spec?

Whats it idle at?

How many inches of vacuum does it pull at idle?

Solid Lifter Roller Camshaft (add $ 600.00) -

hmm whats the reason for this?



UD

im not 100% sure on the mounts I thought the 454 and 350 mounted the same.
How much difference would wet headers make and why?
I'm guessing you don't know the use of a solid lifter cam then if you are asking. It has no place in the marine world since engines don't rev that high. Solid lifters replace hydraulic lifters in high revving engines. I am not sure of the rpm exactly maybe around 8000rpm when the hydrauliic lifters start to float. The solid lifters compensate for that and they also require alot more adjusting

Uncle Dave

I know - I have a solid lifter set up-
(I said this in an earlier post )


UD

twistedvelocity

what rpms are you running?

Uncle Dave

See post #93

I describe where this combo of parts "comes on" and "lays down".

UD

twistedvelocity

lol making me work for it lol
Why did you choose solid lifters?
Now that I think about the rpms boats run I don't see much of a place for them in boats

Uncle Dave

Doesn't seem to make any sense to pay more for this combo when you saw my RPM range huh?..hmmm
