John,

I thought the original B1 would (or could be made to)work.

I'm really leaning toward a 440-25 but I can't find any data on it. With these ports and 2-4's I think there could be big gains worth going after upstairs. Besides, I never really had a multi-carb street car!

Bobby, I've got a Eddy TM7 that has been nicely modified to accomodate Max Wedge ports. I have it sized for raised port B/RB heads. There is alot of material above the port that can still be removed. I also increased the runner size on a couple ports, but the work came to a standstill when I found a Wieand dual quad and a heavily modified tunnel ram to suit my heads. If you want some pics, let me know. I'm taking it to a swap meet Saturday with some other stuff I don't plan on using. It likely won't sell in unfinished condition.

Phil,

Hey, thanks buddy!

I'm still a good bit away from getting anywhere near assembly, I actually have a project ahead of the 517 that needs to be finished and the starter just went out on the Charger (defective bendix, I guess)

I'm leaning toward multiple carbs on this thing and that INDY rat roaster looks pretty cool, wish I could find more 'real' info about it.

Can somebody (Mods?) revise the BB head flow chart in the Archives to add these?

I figure it might save Fast and me a bunch of E-mails when people want to remember what they went.

thanks

i'll see what needs to be done , what i need is a post with the numbers you want added so i can give them to tom ...

So where's your 260 #'s? Did Dwayne have 11/32 valves? I'll bet he does, that's standard Indy size too IIRC

indy size is 2.20 at 5.4 ??

haven't sent them up , he never responded if he had the valve when i asked in the post , probably didn't see it ...

Oh, is it 2.200"? My bad, thought it was 2.19".

He can use the indy length or BBC for flow 'checking springs', pretty sure that's what he did with mine.

We know he has the exhaust valve

what did you end up doing for valves ??

Ain't got 'em yet, heck I still only "Have" one head!

I'll wait till Dwayne sends me the other one, probably get a set of Fereas custom cut. I think Chuck had a good Idea....get all the rocker gear first, check/verify all the geometry (I have some 11/32 "dummy" valves...no 2.200" though, sorry! ), then order the valves.

Makes sense to me

i was wondering , i was thinking of goingthe custom route also .

funny , i only have one head also ...

Maybe you can talk FAST into cutting down the 2.25" for you????

i might have a 2.20 valve laying around.
if not, i'd just get a budget 2.25 BBC valve and cut it down.

John,

Did you send Dwayne the 260's yet?

Got mine back from Dwayne on Friday, now the fun begins and the wallet drains

Billet caps will be on the dance card!!

no , i forgot to bring them over to my dad before i went to the nats , i'm going to run them over tonight for him to drop off tomorrow ...

heres dwaynes numbers vs what chapman advertises for the 260cc head

they might get my car deep into the 12's

Those numbers look comparable to the E.M. heads, except they are stronger in the mid-lifts. It would be interesting to have side by side numbers with the same bore adapter.

Are you running these on the EMC 471 Short John???
AL...
