If anyone has a lead on anyone who has a "takeout" 500EFI cam, please let me know. I'm not in a hurry, and it wouldn't hurt to save a few $$$ over a new Crane cam.

thanks

I'd like to put a small 'plug' in here for carbs.

I've been using the BG 'Sea Demons' (both mechanical sec and vac secondary) for the past few years and absolutely love them. 4 corner idle - glass sight bowls - very little tuning needed if any - built like a 'brick schithouse' - and OSO member Rumrunner is head tech over at BG so he is right here and very reachable if you have any questions.

The 850 has been wonderful on 502's and the 650 on small blocks. Both from very mild to pretty stout engines. Wonderful stuff.

Just my experience which is limited in comparison to many others here.

mech or vacuum secondaries, which do you favor?

Very good question, I really like both of them. The vac secondary carbs have a 2 second (as I call it) quick change secondary spring pod. Awesome btw.

For applications at 1hp per cid or over, I really prefer the mechanical secondary carbs. WOT means WOT.

However, driver / owner has a lot to do with what I pick. The DP's will dilute oil a lot quicker and need a strict oil change schedule. Also, a driver that is 'on/off the gas happy' he/she is less likely a candidate for mech sec's. All those accelerator pumps shots go somewhere other than back to the tank.

A properly sized DP will out run a properly sized vac sec. 98% or more of the time.

BTW: I'll never forget the first Sea Demon I tested. I pulled the bowls to try different jetting and seeing that it had non-stick gaskets put me to my knee's thanking the carb god's !!!

I absolutely dispise taking most Holley's apart for the first time because of the gaskets breaking and being stuck to everything.

Just another plug. Huge in my book !!!

Note about non-stick gaskets: I still advise to have a back up set just in case, especially if doing it on the water on a week-end.

I know, I try and pull them apart before they ever see gas, what would it cost Holley to use the good gaskets?

Or atleast chapstick to coat their gaskets ? LOL.

Chapstick, thats a new one to me, I was told to use Pam spray cooking oil amongst other things. Worked well enough.
