Would BB-5's be better without going to PB1800 Big Duke series

The Magic words,
It's bracket car, weighing 2700 lbs. and appearently on alcohol, IMO the heads are way too small for the most performance out of a 632" motor, but if you already have the heads and intake combo, i would use them unless you have unlimited funds or you are trying to be king of the hill.

__________________________________________________ ___________

I just put together a 476" motor with Brobix 2 plus heads @ 13 to 1 it ran 10.401 @ 128 mph in a 3700 lb car on the 5th pass down the track. The heads are fully ported and on gas 1050 dom.
The cam i think is way too small, the cam i used was a .722 lift. I think you need to be around .760/.780 if you have the converter to handle it.

Kinda funny you mention Holden, i have an Austrailan friend living in Michigan (USA) who has a 1969 holden, who i have sold and bought a few parts from. The car is kind of a cross between a Nova and a Pontiac, but totally different.

What do you mean by apparently.If i wasnt running alcahol i would tell you otherwise so i could get the best out of my application.This is my first Methanol car so im new to it all and would like your opinion not criticism.
Thanks.Have a look on my racing junk profile at the Monaro if you wish.

Tod74

I don't think he was criticizing you at all. Not sure what he ment by apparently but I would bet the farm he meant nothing negative by it at all...he isn't like that from what I have seen on here....always give good knowledgeable advice.

WOO,WOO, my friend, i only assumed you're running alcohol because of the bird catcher. I meant no criticisium, Jesus i've been running alcohol for ever. We run 3 cars & 2 rails on alcohol the cars run in the 5's and the rails run in the 4's, i only meant to offer advice as my own experience. I also have a blown S/BLK. alcohol motor that's been 4.60's @ 2600lbs. My first blown car was 44 yrs. ago which set a world record 42 yrs. ago. My fastest car ran 6.71 @ 217mph 20 yrs. ago.
I now go a little slower, but i'm building a S/BLK 1471 blown alcohol 48 Anglia that should dip into the 4's.
Again i appolagize if you mis understood my post, it was not to be accepted as negative of your setup.

With that said i'll bail out with further advice or comment on this post, i donot want to make enemies, nor do i ever want to be accused of critising someone for what they have or trying to run with their setup.

With that said here is my 358" that went 4.60's @ 2600lbs, don't worry about the smoke it's just a valve cover leak.
And yes i wish you the very best luck and i hope you run as good as you want too, your friend

PS, Tod74 you know you're right i have never critised anyone and will never do that.

I'm behind the camera on this vid, my motor is in my friends car Jeff Russell's ugly Dodge @ 2600 lbs.

In the conventional head world you need them heads I suggest or a big duke.. you could really upgrade them by going to a 3x head instead of 2x. You are very limited by that head and will loose a lot of power with them 450cfm may not be out of the question on certain flow benchs but on a good honest one I just dont see it. Still should make a 1000hp though lot of cubes with plenty of compression.
