305's will support a 540 but you are at the edge of where you want to be. If you have the money, the 315cnc's are going to be a much better choice. Assuming of course that you have the airflow from the carb or efi and the cam to take advantage of the heads. AFR can do some additions to the 305's to make them a bit better than the basic ones, again depending on the dollars you have to spend. You can call AFR and ask them for specifics. I'd tell you who else to call, but then some people on this thread will get into name calling which won't help you.

Well it looks that I misspoke, so with that said- my memory served me wrong and I am sorry. Either way- the only used parts that went into my engines were the cams I purchased from you. I bought just about everything I saw back then if it was a good deal. Whether I was going to use it or not. So it's a little difficult to remember what I paid for every part.
As I'm sure you also know- those emails are from 2012, and right at the very beginning of me planning on what I was going to do with my engines at that time. In the end- using old parts didn't set well with me and I sold off just about every part I bought. So just for the record here is what went into my "junk" engines
Crain Gold Rockers
Morel Lifters
Trend push rods
RPM intakes to later be replaced with Darts
Crane 741 cams
HP 500 Carbs
Holley Fuel Pumps
Isky SP-8005 Springs
Isky Retainers and Locks
Arp rocker studs
ARP head bolts, intake bolts, ect.
Cometic gaskets
Wilson Carb Spacers
Other than the carbs, and the intakes, every thing was new. So there you have it, so now maybe you can stop thinking that the parts I bought from you in 2012, were ever installed in my engines. Again- outside of the cams- nothing ever went in my engines. Also- those cams never made more than 380 hp, They were sad and weak, they worked for the time being, but certainly never produced the 467 hp you thought they would. Over the 330's that were in my boat originally, I gained 3 mph with the same props.

Lets see Tim you have over 7000 posts and 6999 of them are about YOUR 2 boats that have so many failures by your own hands over the past 5 or so years I can't even keep track of them. Now that you have got 1 of them to run for 10 hours you are all about giving advise................BRAVO YOUR THE BEST.............I will PM you later about a new build we are working on so you can teach me the right way.
Go part out that 30,000.00 empty Baja hill you could not sell, I told you that last winter you hated me for pointing out it will not sell and that's what started your hate towards me... Funny my dumb azz was right... As you are now gonna scrap it!!! Hahahahahahahahaha

I ended up buying two sets of crane golds off a buddy. They were low hour ones, he purchased them new in 05, and only like 100 hours on them. Mine, could have very well been from the 80's, as I believe my engines started life as 400HP mercs.
Scorpions endurance were my #1 choice. But since this build has gone way over the initial budget, tryin to save some money here or there!

Wow- so now you are going through all of your old e-mails. You must have a lot of time on your hands. I've used both Crane Golds and Scorpion Endurance rockers. Of the two I prefer the Scorpions. So I really don't know what you are attempting to prove with the last e-mail, but using my opinion and not Bobs, I think the scorpion is a better product. Use what you want, I could careless. Again- what is the point of that post?
Never made more than 387hp ? You dynoed them? As stated. Those cams were in 509s, that made over 500hp NA , and 700hp with 250 blowers. I gave you the specs, you decided to purchase. Please stop insinuating i specd out some junk for your engines. You consulted with bob on them, and he advised going with 1.8 rockers with them. Do not blame me for your lack of engine knowledge, tuning knowledge, or how to set up a boat.
And those lifters you bought from mike tkach, were indeed morel lifters, the street version, which both him and i told you prior to purchase.

The key to this is how you get the air fuel in. The reason that in 2 identical engines, one with 088 heads and one with afr's are going to make different hp. Naturally with the other correct parts.

Id love to hear what you like better about the scorpion rockers over the cranes ?? Is the the geometry with aftermarket taller intake valves ?

gee I don't know. Why would you do port work on 305's to make them flow more air? As far as extras, if you hadn't pissed AFR off by calling their heads junk maybe they should tell you. Or maybe you could just read their website.
