just out of curiosity, a question for those of you building your combos's with the heads mentioned. how big is the cam your running and at what compression ratio?

indy legend heads, cnc ported, indy offset crossram intake,heads flows 450 cfm, .737 lift solid roller cam and 11.2:1 compression.runs mid 9's on pump gas and a spritz of 110 race fuel.

I gots me a .466+ lobe lift flat tappet from Barton that will go in first...Then a Old crane grind which has about .475 lobe lift roller. I say this cause i dont know what ration these rocker arms are, some say 1.6 some say less.

Compression is 14:1

Just a friendly debate, I dont get worked up over the internet...I laugh a bunch more than most normal people

Its winter time dang it....and I havent raced but twice in almost a whole year...now im starting to get mad.

Do i win a prize Dan-O for the largest flat tappet on the web site or something...

I guess it would be funny if I was running a .500 lift cam talking about all this flow.

I agree completely with cre!
The flow bench dyno nationals.
They are just tools
I'm running a .650ish" roller. 9.0:1 procharged.

I dont believe I want any of that engine on a dyno contest...I recall what it made power wise..

Had a set of raised exhaust port St.V's done by Jeff @ MCH, 490 CFM int., 326 CFM exhaust. Was going to use .950ish lift and 15.5 comp but sold it all to go another direction

well, if i was going to give you a prize for that flat tappet that'll end up around .755 lift, it wouldn't be anything to be proud of.

by the way, the S/R heads won't even come close to the power potential of the raised port big valve or millenium stage 5's.

the reason i asked about the cams and combo's is because the supposed 10 cfm difference doesn't amount to squat. until you build something of real potential, it's meaningless and not even worth worrying about.

for example, go ahead and run that silly flat tappet cam and somebody else running a well designed roller 10 degree's smaller with 10 less cfm will put you on the trailer. see my point?

Oh
I see..so flat tappet cams are silly...hmm thats a different way of putting it.
Let me ask you this...Do you base all flat tappet cams in the silly category?
So does a Hyd flat tappet cam fall in the stupid column? Or are they grouped together as one big silly family?
To be Honest the only reason im not running the roller is cause I dont have the money for a good set of roller lifters, roller springs etc.. Just to be clear...
Im currently Un-employed. And I currently have the "Silly" flat tappet stuff

BTW how does flow rates and cam style having any thing to do with cutting a light in bracket racing



If Im not mistaken I was thinking that was kind of a Cheap shot towards me Dan..So let me ask you, do you think Im just silly in general?
Your opinion is obviously very important to me
I think I will call up Comp Cams and ask them why they even bother grinding those flat tappet cams..

Now I know the raised port hemi heads rule...kinda why I ask...I was looking for a more In depth answer than just

I dedicate a new sig line just for you Dan-the-man

i guess if every post i make isn't a PC atta boy, you betcha, this is what i should expect.call me and i'll explain it to you.

Naa
I take your advise very seriously Dan, I think honestly you generally want to help people, and offer good advise...

Ill keep the Barton Custom Grind "silly cam" (Bullet Racing)..
He assure me he has some practice developing a max effort solid flat tappet cam...
I would imagine he has spent more time on the dyno testing Hemi cams as about anyone.

Let me ask you this though...
I cant seem to find any were in this thread where I posted any specs other than lobe lift..but your so sure that it's a poor cam choice, and yours would be better correct? How much time honestly have you spent on the dyno with a Hemi engine developing a flat tappet Max effort cam?
He told me he has a fortune in scrap short iron in the attic with tested flat tappet cores.

He actually told me that it works with power brakes. LOL..
He was pretty secretive with the cam profile, and wouldnt actually tell me the valve events until I payed for it LOL..
He also told me this is the cam you get in a few crate engine including a 528 pump gas Hemi with 9:1 compression that makes 650+ hp on 87 octane fuel...
I have also spent some time on the phone with Harold the cam guru that works for Bullet, that designed a bunch of cams for UltraDyne. He worked with those guys in this and a few cams developments.

Thanks for the offer though.

This will be my last post on this topic, and have talked with a few guys through Pm's about what I was trying to get across in this thread. (I will reply tomorrow guys).

In a nut shell, every time these MP heads are mentioned...many comments about how there junk, seats falling out etc...we have all read these comments.
And I dont blame them for being mad or PO'd..But these are not no where near the same head, same casting, same machine work, or even from the same foundry as older versions.
Thats all, just a good quality, cheap alternative hemi head...If not the cheapest available.

okay
most guys won't give out the timing events until you pay for the cam. there's a good reason for that. if your plan is to run 87 octane and make 650HP, good luck with your plan.

sorry to get off the main subject guys. i'll get out of the way now. please continue.

Dont forget about the newer MP/Edelbrock castings

These things flow a ton, and are the best thing out there for a hemi head that is a true SR type deal..stock valve angles, and port locations..

Modern cylinder Ported mine and got 460cfm from them.. The SR Stage V's wont flow that

I have all kinds of pics, and flow sheets..PM m if your interested I will email them too you.
