651??? made by crane???
curious what are the numbers on this cam??

Sure did...





Would the 651 cam have caused reversion with my wet exhaust ? Seems many who run it run dry exhaust .


As far as the IAT, it was close to 100° in the shop when we dynod and I was feeding the intercooler off the bypass port on the crossover , so the water was heated some by the block.. When it finally goes in the boat it'll likely have its own pickup...

Thank you all. I find it interesting that the power curve of th SC just keeps climbing with that small of a cam and NA it falls off around 5500.

May have pulled even more with the SC we didn't try..
I chickened out due to my Eagle rotating assembly, AND due to the fact it was already well above my target hp anyways..

Sure doesn't sound like 1000+ hp at idle..

A SC and Turbo supplies more air then the motor does NA, thus able to feed the motor at higher rpm's than NA.

My gosh.... It's gotta be hilarious when some fool pulls up to you with his ratty sounding 454/502/540 and you drop the hammer. I would swear that sounds like a 330 or ok maybe a mag but... Good for you. That's awesome.

if the center of the piston is .005 above deck and has .018 out of the bore during cold rock it is .018 above and below center line of piston with a flat top.yes as the piston gets to operating temp it is growing so the .018 rock will be less when at operating temp.so lets say the rock goes to .008 at operating temp,now add .010 for carbon buildup you still need to allow .018 when figuring what head gasket to use.this is why i said i would use a .060 thick gasket.a little extra clearance won,t hurt but not enough clearance will cause all kinds of problem,s.this is how i have done it for 40 years so i guess it is working.don,t forget that the piston rock is .018 during cold running until the piston starts to grow and with the build up of carbon on the piston top one must allow clearance for it.

info is in post 6.

One thing to look at is his IAT is without fuel so he don't show any cooling effect VS a roots supercharger with fuel.

For sure. It still is what it is though. It be pretty cool to see what a non intercooled procharger does, vs a non intercooled roots. I know what the temps are with a non intercooled carb'd 1071 roots at 6k rpm. Still no where near as hot as the internet claims, but about 25-30 degrees hotter than the intercooled version. Im not super impressed with the "superchiller" brand intercooler results. Maybe the whipple ones work better, but they are sure expensive.

The Port EFI isn't getting the fuel cooling effect, but it should offer some help in the fuel distribution if its tuned right.
