i have two 2000 efi long blocks and just bought a set of b+m 420 mega blowers with 850 holleys just wondering how the efi cam will work with this set up thanks

That cam is great with the stock heads and long runner intake on the EFI engine. I wouldn't bother changing it unless I was planning to run lots of boost with the Roots style blower.

We just dynoed a 500EFI engine with a Vortech blower and got 800 HP @ 5500 and 7 psi boost. Stock heads and cam; intake modified to take intercooler.

Nice looking package Tom!

How's the Skater project coming along? Have you tried the new props?

i dont have the efi units, i bought just the long blocks - then i got hp500 intakes and carbs to make them carb hp500s. But then i came across these blowers ( two complete setups ) so things change. im not planing on running more than 5lbs boost i want them reliable.

Then there's nothing wrong with those cams. If the long blocks are in good shape you're good to go.

Hi Kurt: Still waiting for the final prop testing.

thanks tom , yours looks great

Just thinking a little more about this. The stock head gaskets on those engines have given some problems, especially when supercharged. Are the engines fresh? If not you might consider doing the heads and using Cometic head gaskets. That's what we did on the engines shown above. Added ARP rod bolts too for a little more insurance as supercharged engines tend to get revved a little higher.
