Seems that my little 557's need more cam.
The engine builder dyno'd the first one last week and found that the power started to drop off at around 4800rpm.
It still made 837hp but at too low of an rpm.
So its up 10deg. of duration for both sides.
They were 238/[email protected]
He is to get back to me later today with the new pull numbers.

Tell us more - heads, blower, carbs, CR, etc.

Look under thread..."Oh I can't wait any longer" in this FOUNTAIN Forum.

557ci Dart tall decks with Callies cranks, Oliver rods, Ross pistons, Canfield 350 heads, Isky hyd. roller cams...all force fed with BlowerShop 10-71's.
We have a 93 42 Lightning with Bravos...upgrading that to
IMCO boxes with Extreme SC's.

Mark,
How is the project coming? Are you going to be finished for SOTW?

I found my "leak". The drive reservoir cap was not pressurizing. Hope to see you out on the big puddle soon.
