We had a 540 short block built about 6 years ago with the intention of running it in our TR2 (Former SPOOKY Boat). We ended up using a different set up and the 540 sat in the garage until now. Iíll be putting it in a 21í V-Drive Rayson Craft and wanted to get some suggestions on what needs to change in the set up.
This boat will not be my primary boat, just a water hot rod that Iíll take out on occasion for blasts up and down the river and head into Havasu on occasion. I wonít be doing any watersports behind it, but it will spend some time idling through 5mph zones (in the gorge going to and from the lake). It will be set up with EFI and tuned for 91 octane. The details of what I have are listed below, please let me know if I need to add anything else.
Everything is new and only short block is assembled
JE Pistons PN181990
Eagle 4340 Crank
Eagle CRS63853d Rods
Rotating assembly internally balanced
Brodix BB-2 heads with Port & Polish and valve job by Mike at Sissells Automotive
Manley 221424 valve springs, 250lb seat, 800lb open, .880Ē max lift
Manley severe duty SS valves and Ti retainers
We got the cam from Bill Barnes, Iím guessing this is one of the parts Iíll have to change out?
Lift .775 intake, .740 Exhaust,
Intake opens 31 BTDC, Closes 73 ABDC, max lift 109, Duration 284

Morel Sportsman roller Lifters (we thought these were solid when we purchased them, but realize now after opening the box that theyíre hyd.)
Mildon Gear Drive #12700
Intercooled Littlefield mag 1271. Planned on running around 10lbs of boost
MS3x EFI using modified Enderle Hat as the TB
Ign will be COP with LS truck coils
Not sure if it matters, but it will be running through a TH400
I have a separate thread for feedback on using the Enderle hat with EFI on a cruiser. I know this isnít ideal, but itís something Iím having fun with trying to make it work.
The main issue I see is the cam. Will this work or do I have to swap it out? If swap, what cam does everyone suggest? Iím guessing the cam selection will determine if I use the Morel hyd lifters or sell them for solid (donít mind running valves every once and a while so solid lifters arenít an issue)? What else should I change? If possible with the feedback, Iíd like to know if the suggestions are ďMust ChangeĒ or ďIt will work, but work better if changedĒ so I can try to prioritize the money Iím burning on this project
As usual, I really appreciate all the help from everyone over the years. Makes the sport much more enjoyable for NOOBs like me!
